Retinoids signal via nuclear transcription factors belonging to the retinoic acid receptor (RAR) and retinoid X receptor (RXR) families. Inactivation of RARaplpha and RARbeta2 receptors together, but not singly, resulted in renal malformations, suggesting that within a given renal cell type, their concerted function is required for renal morphogenesis. At birth, RARalpha beta2(-) mutants displayed small kidneys, containing few ureteric bud branches, reduced numbers of nephrons and lacking the nephrogenic zone where new nephrons are continuously added. These observations have prompted us to investigate the role of RARalpha and RARbeta2 in renal development in detail. We have found that within the embryonic kidney, RARalpha and RARbeta2 are colocalized in stromal cells, but not in other renal cell types, suggesting that stromal cells mediate retinoid-dependent functions essential for renal development. Analysis of RARalpha beta2(-) mutant kidneys at embryonic stages revealed that nephrons were formed and revealed no changes in the intensity or distribution of molecular markers specific for different metanephric mesenchymal cell types. In contrast the development of the collecting duct system was greatly impaired in RARalpha beta2(-) mutant kidneys. Fewer ureteric bud branches were present, and ureteric bud ends were positioned abnormally, at a distance from the renal capsule. Analysis of genes important for ureteric bud morphogenesis revealed that the proto-oncogene c-ret was downregulated. Our results suggest that RARalpha and RARbeta2 are required for generating stromal cell signals that maintain c-ret expression in the embryonic kidney. Since c-ret signaling is required for ureteric bud morphogenesis, loss of c-ret expression is a likely cause of impaired ureteric bud branching in RARalpha beta2(-) mutants.  (+info)

Observations on some additional abnormalities in situs inversus viscerum. (2/868)

The abnormal findings in a case of Situs inversus totalis are described. The duodenum was placed abnormally and retained its primitive mesentery. The proximal 22 in of jejunum were retroperitoneal. The attachment of the root of the mesentery to the posterior abdominal wall had a 7-shaped appearance, and there was a partial failure of the primitive mesocolon to adhere to the posterior abdominal wall. The common hepatic artery arose from the superior meseneric artery, which also provided a branch to the proximal jejunal loop. The right vagus nerve was found anterior to the oesophagus at the oesophageal hiatus in the diaphragm, and the left vagus was posterior. A double ureter was present on the right side. The findings are discussed in relation to mid-gut development.  (+info)

Dominant effects of RET receptor misexpression and ligand-independent RET signaling on ureteric bud development. (3/868)

During kidney development, factors from the metanephric mesenchyme induce the growth and repeated branching of the ureteric bud, which gives rise to the collecting duct system and also induces nephrogenesis. One signaling pathway known to be required for this process includes the receptor tyrosine kinase RET and co-receptor GFR(&agr;)-1, which are expressed in the ureteric bud, and the secreted ligand GDNF produced in the mesenchyme. To examine the role of RET signaling in ureteric bud morphogenesis, we produced transgenic mice in which the pattern of RET expression was altered, or in which a ligand-independent form of RET kinase was expressed. The Hoxb7 promoter was used to express RET throughout the ureteric bud branches, in contrast to its normal expression only at the bud tips. This caused a variable inhibition of ureteric bud growth and branching reminiscent of, but less severe than, the RET knockout phenotype. Manipulation of the level of GDNF, in vitro or in vivo, suggested that this defect was due to insufficient rather than excessive RET signaling. We propose that RET receptors expressed ectopically on ureteric bud trunk cells sequester GDNF, reducing its availability to the normal target cells at the bud tips. When crossed to RET knockout mice, the Hoxb7/RET transgene, which encoded the RET9 isoform, supported normal kidney development in some RET-/- animals, indicating that the other major isoform, RET51, is not required in this organ. Expression of a Hoxb7/RET-PTC2 transgene, encoding a ligand-independent form of RET kinase, caused the development of abnormal nodules, outside the kidney or at its periphery, containing branched epithelial tubules apparently formed by deregulated growth of the ureteric bud. This suggests that RET signaling is not only necessary but is sufficient to induce ureteric bud growth, and that the orderly, centripetal growth of the bud tips is controlled by the spatially and temporally regulated expression of GDNF and RET.  (+info)

A2B adenosine receptors mediate relaxation of the pig intravesical ureter: adenosine modulation of non adrenergic non cholinergic excitatory neurotransmission. (4/868)

1. The present study was designed to characterize the adenosine receptors involved in the relaxation of the pig intravesical ureter, and to investigate the action of adenosine on the non adrenergic non cholinergic (NANC) excitatory ureteral neurotransmission. 2. In U46619 (10(-7) M)-contracted strips treated with the adenosine uptake inhibitor, nitrobenzylthioinosine (NBTI, 10(-6) M), adenosine and related analogues induced relaxations with the following potency order: 5'-N-ethylcarboxamidoadenosine (NECA) = 5'-(N-cyclopropyl)-carboxamidoadenosine (CPCA) = 2-chloroadenosine (2-CA) > adenosine > cyclopentyladenosine (CPA) = N6-(3-iodobenzyl)-adenosine-5'-N-methylcarboxamide (IB-MECA) = 2-[p-(carboxyethyl)-phenylethylamino]-5'-N-ethylcarboxamidoaden os ine (CGS21680). 3. Epithelium removal or incubation with indomethacin (3 x 10(-6) M) and L-N(G)-nitroarginine (L-NOARG, 3 x 10(-5) M), inhibitors of prostanoids and nitric oxide (NO) synthase, respectively, failed to modify the relaxations to adenosine. 4. 1,3-dipropyl-8-cyclopentylxanthine (DPCPX, 10(-8) M) and 4-(2-[7-amino-2-(2-furyl) [1,2,4]-triazolo[2,3-a][1,3,5]triazin-5-ylamino]ethyl)phenol (ZM 241385, 3 x 10(-8) M and 10(-7) M), A1 and A2A receptor selective antagonists, respectively, did not modify the relaxations to adenosine or NECA. 8-phenyltheophylline (8-PT, 10(-5) M) and DPCPX (10(-6) M), which block A1/A2-receptors, reduced such relaxations. 5. In strips treated with guanethidine (10(-5) M), atropine (10(-7) M), L-NOARG (3 x 10(-5) M) and indomethacin (3 x 10(-6) M), both electrical field stimulation (EFS, 5 Hz) and exogenous ATP (10(-4) M) induced contractions of preparations. 8-PT (10(-5) M) increased both contractions. DPCPX (10(-8) M), NECA (10(-4) M), CPCA, (10(-4) M) and 2-CA (10(-4) M) did not alter the contractions to EFS. 6. The present results suggest that adenosine relaxes the pig intravesical ureter, independently of prostanoids or NO, through activation of A2B-receptors located in the smooth muscle. This relaxation may modulate the ureteral NANC excitatory neurotransmission through a postsynaptic mechanism.  (+info)

Vesicoureteral reflux in male and female neonates as detected by voiding ultrasonography. (5/868)

BACKGROUND: Vesicoureteral reflux (VUR) is assumed to be congenital, and its early diagnosis is desired in order to prevent acquired renal damage. However, the incidence of VUR in neonates remains to be revealed. METHODS: Two thousand newborn babies (1048 boys and 952 girls) underwent voiding ultrasonography (an ultrasound examination of urinary tract during provoked voiding). Those who showed transient renal pelvic dilation during voiding, who had small kidneys, or who subsequently developed urinary infection underwent voiding cystourethrography. RESULTS: Transient renal pelvic dilation was observed in 16 babies (0.8%), including one boy with small kidneys. Among the rest of the babies, one boy had a small kidney, and nine babies subsequently developed urinary infection. Voiding cystourethrography revealed VUR in 24 ureters of 16 children (11 boys and 5 girls). Dimercaptosuccinate renoscintigraphy confirmed small kidneys, with generally reduced tracer uptake in a total of three boys, all having VUR. Voiding ultrasonography detected transient renal pelvic dilation in 17 (71%) of the 24 kidneys with VUR and, strikingly, 16 of the 17 (94%) kidneys with high-grade VUR (grade III or more). CONCLUSION: This study effectively detected VUR in 0.8% of the neonates (mostly of high grades and predominantly in males) and voiding ultrasonography showed a decided usefulness for the detection of VUR. The male preponderance of VUR in neonates was considered to be due to the occurrence of congenitally small kidneys, with reflux found exclusively in males and easier ultrasound detection of VUR in male neonates because the majority of diagnoses are reported to be high grades of VUR.  (+info)

Tissue inhibitor of metalloproteinase-2 stimulates mesenchymal growth and regulates epithelial branching during morphogenesis of the rat metanephros. (6/868)

Development of the embryonic kidney results from reciprocal signaling between the ureteric bud and the metanephric mesenchyme. To identify the signaling molecules, we developed an assay in which metanephric mesenchymes are rescued from apoptosis by factors secreted from ureteric bud cells (UB cells). Purification and sequencing of one such factor identified the tissue inhibitor of metalloproteinase-2 (TIMP-2) as a metanephric mesenchymal growth factor. Growth activity was unlikely due to TIMP-2 inhibition of matrix metalloproteinases because ilomastat, a synthetic inhibitor of these enzymes, had no mesenchymal growth action. TIMP-2 was also involved in morphogenesis of the ureteric bud, inhibiting its branching and changing the deposition of its basement membrane; these effects were due to TIMP-2 inhibition of matrix metalloproteinases, as they were reproduced by ilomastat. Thus, TIMP-2 regulates kidney development by at least 2 distinct mechanisms. In addition, TIMP-2 was secreted from UB cells by mesenchymal factors that are essential for ureteric bud development. Hence, the mesenchyme synchronizes its own growth with ureteric morphogenesis by stimulating the secretion of TIMP-2 from the ureteric bud.  (+info)

The renal lesions that develop in neonatal mice during angiotensin inhibition mimic obstructive nephropathy. (7/868)

BACKGROUND: Inhibition of angiotensin action, pharmacologically or genetically, during the neonatal period leads to renal anomalies involving hypoplastic papilla and dilated calyx. Recently, we documented that angiotensinogen (Agt -/-) or angiotensin type 1 receptor nullizygotes (Agtr1 -/-) do not develop renal pelvis nor ureteral peristaltic movement, both of which are essential for isolating the kidney from the high downstream ureteral pressure. We therefore examined whether these renal anomalies could be characterized as "obstructive" nephropathy. METHODS: Agtr1 -/- neonatal mice were compared with wild-type neonates, the latter subjected to surgical complete unilateral ureteral ligation (UUO), by analyzing morphometrical, immunohistochemical, and molecular indices. Agtr1 -/- mice were also subjected to a complete UUO and were compared with wild-type UUO mice by quantitative analysis. To assess the function of the urinary tract, baseline pelvic and ureteral pressures were measured. RESULTS: The structural anomalies were qualitatively indistinguishable between the Agtr1 -/- without surgical obstruction versus the wild type with complete UUO. Thus, in both kidneys, the calyx was enlarged, whereas the papilla was atrophic; tubulointerstitial cells underwent proliferation and also apoptosis. Both were also characterized by interstitial macrophage infiltration and fibrosis, and within the local lesion, transforming growth factor-beta 1, platelet-derived growth factor-A and insulin-like growth factor-1 were up-regulated, whereas epidermal growth factor was down-regulated. Moreover, quantitative differences that exist between mutant kidneys without surgical obstruction and wild-type kidneys with surgical UUO were abolished when both underwent the same complete surgical UUO. The hydraulic baseline pressure was always lower in the pelvis than that in the ureter in the wild type, whereas this pressure gradient was reversed in the mutant. CONCLUSION: The abnormal kidney structure that develops in neonates during angiotensin inhibition is attributed largely to "functional obstruction" of the urinary tract caused by the defective development of peristaltic machinery.  (+info)

The effect of cyclopiazonic acid on excitation-contraction coupling in guinea-pig ureteric smooth muscle: role of the sarcoplasmic reticulum. (8/868)

1. We have investigated the effect of cyclopiazonic acid (CPA), an inhibitor of the sarcoplasmic reticulum (SR) Ca2+-ATPase on excitation-contraction (EC) coupling in guinea-pig ureter, by measuring membrane currents, action potentials, intracellular [Ca2+] and force. 2. CPA (20 micrometers) significantly enhanced the amplitude and duration of phasic contractions of ureteric smooth muscle associated with action potentials. This was accompanied by an increase in the duration of the intracellular Ca2+ transient in intact tissue and single cells but not their amplitude. However, CPA also slowed the rate of rise, and fall, of the force 1|1|Phiand1Phi Ca2+ transients. 3. Membrane potential recordings showed that CPA produced a small depolarization and a large increase in the duration of the plateau phase of the action potential. 4. Patch-clamp studies showed marked inhibition of outward potassium current in the presence of CPA and an inhibition of spontaneous transient outward currents (STOCs). CPA had no effect on inward Ca2+ current. 5. These data suggest that the SR plays a major role in modulating the excitability of the ureter, particularly via curtailing the action potential duration. This in turn will shorten the Ca2+ transient and decrease force. This negative action on developed force predominates over any small role it may play in initiating force in the guinea-pig ureter.  (+info)

Ureteral duplication is the most common congenital anomaly of the urinary tract, with an estimated incidence in the general population of 0.8-5% from autopsy studies [1,2,5]. The congenital malformation consists of two ureters connected to one kidney, resulting from duplication or division of the ureteric bud, the embryonic origin of the ureters [1,3]. The superior bud derives from the upper pole of a duplicated kidney and the inferior bud derives from the lower pole. Generally, superior bud is carried inferiorly along with any derivative of the distal mesonephric duct, so the ectopic ureter drains the upper pole of the duplicated kidney and the two ureters cross each other [6]. Therefore, the orifice of the ureter communicating with the upper pole in the complete type of ureteral duplication is located more medial and inferior than the normal position, but that of the ureter communicating with the lower pole is located more lateral and superior than the normal position, as described by the ...
A nine year old male castrated Siberian Husky presented with a history of cyclic fever, anorexia and lethargy of one year in duration, along with chronic urinary tract infections and urinary incontinence. Initial diagnostics revealed a progressive pneumonia, an intramural ectopic left ureter, and left-sided hydroureter and hydronephrosis. The ectopic ureter was corrected via a ureteral transposition, and the animal recovered well from the procedure. Ectopic ureters are a common cause of urinary incontinence since birth or weaning. They may be unilateral or bilateral, and intramural or extramural. The cause of this abnormality is debated, but it is likely dependant on genetic factors. Ectopic ureters are often associated with other structural or functional abnormalities, which should be identified prior to surgery. Surgical correction may be accomplished via a neoureterostomy and urethral / trigone reconstruction, a ureter transposition, or a nephroureterectomy ...
Kidney development depends on reciprocal signaling between metanephric mesenchyme that differentiates into the nephron, the ureteric bud epithelium that forms the collecting duct system, and stromal mesenchyme that differentiates into the renal interstitium. As the fetal kidney grows, nephron induction and branching morphogenesis occur continuously in the nephrogenic zone in the outer cortex, while further differentiation occurs in deeper regions of the kidney. In the nephrogenic zone, ureteric bud tips generate signals important for survival and maintenance of nephron progenitors while, at the same time, signals from metanephric mesenchyme, which trans-differentiates into the epithelial components of the nephron, induce ureteric bud tips to grow and branch (Grobstein, 1953). Surrounding ureteric bud branches and nephron progenitors, cortical stromal cells generate signals required for nephron differentiation and branching morphogenesis (Hatini et al., 1996; Levinson et al., 2005).. Retinoic ...
The subject of the investigation is the mechanism of autoregulation of blood flow in the intact kidney. The left kidney of the anesthetized dog was exposed via a flank approach. Renal venous outflow was measured during control periods and following separate elevations of renal artery pressure, renal vein pressure, and ureteral pressure. Extravascular pressure (tissue pressure) was estimated by obtaining values of (a) deep vein pressure; (b) needle pressure; (c) and (d) large vein pressure and ureteral pressure elevations resulting in significant decreases in renal blood flow. Results are in agreement with previously reported studies regarding the important role of extravascular pressure in autoregulation. Increases in renal artery pressure result in elevations of extravascular pressure which compress the renal vasculature. Increases in renal vein and ureteral pressures did not decrease renal blood flow until approximating or exceeding resting tissue pressure. Results from carotid artery occlusion
Abstract. Congenital anomalies of the kidney and urinary tract (CAKUT) are among the most common developmental defects in humans. Despite of several known CAKUT-related loci (HNF1B, PAX2, EYA1, etc.), the genetic etiology of CAKUT remains to be elucidated for most patients. In this study, we report that disruption of the Holliday Junction resolvase gene Gen1 leads to renal agenesis, duplex kidney, hydronephrosis, and vesicoureteral reflux (VUR) in mice. GEN1 interacts with SIX1 and enhances the transcriptional activity of SIX1/EYA1, a key regulatory complex of the GDNF morphogen. Gen1 mutation impairs Grem1 and Gdnf expression, resulting in excessive ureteric bud formation and defective ureteric bud branching during early kidney development. These results revealed an unidentified role of GEN1 in kidney development and suggested its contribution to CAKUT. ...
In vitro data indicates that GDNF continues to play a prominent role during early branching (Qiao et al., 1999a; Vega et al., 1996). Transcriptional modulators of GDNF expression also influence ureteric branching. For example, Emx2, a homeobox gene expressed in UB epithelia during early branching, maintains expression of GDNF in the MM. Murine Emx2 knockouts exhibit normal UB budding, but the absence of subsequent branching events leads to rapid mesenchymal apoptosis and renal agenesis (Miyamoto et al., 1997). Similarly, maintenance of localized Ret expression in the ureteric bud tips via expression of RARα, RARβ2, Foxd1 and Pod1 appears to be crucial for proper branching morphogenesis (Hatini et al., 1996; Mendelsohn et al., 1999; Quaggin et al., 1999). Homozygous null mutation of Rara, Rarb2, Foxd1 and Pod1 results in decreased ureteric branching within the embryonic kidney (Table 1).. Although GDNF plays an important role in continued branching morphogenesis, in vitro studies indicate that, ...

The transforming growth factor-β (TGFβ) family signaling pathways play an important role in regulatory cellular networks and exert specific effects on developmental programs during embryo development. However, the function of TGFβ signaling pathways on the early kidney development remains unclear. In this work, we aim to detect the underlying role of TGFβ type II receptor (TβRII) in vitro, which has a similar expression pattern as the crucial regulator Six2 during early kidney development. Firstly, the 5-ethynyl-2′-deoxyuridine (EdU) assay showed knock down of TβRII significantly decreased the proliferation ratio of metanephric mesenchyme (MM) cells. Additionally, real-time Polymerase Chain Reaction (PCR) and Western blot together with immunofluorescence determined that the mRNA and protein levels of Six2 declined after TβRII knock down. Also, Six2 was observed to be able to partially rescue the proliferation phenotype caused by the depletion of TβRII. Moreover, bioinformatics analysis and

In addition to its growth-promoting function, BMP4 has another effect on the branching ureter, i.e., inhibition of ectopic budding in the stalk of the ureter. Although the incidence is low, of 64 Bmp4+/- newborn mice, 4 were found to have a distinctive phenotype of duplex kidney with bifid ureters. The duplex collecting system is thought to be attributed to additional ureteral budding from an aberrant position in the WD or the ureter during early stages of kidney and urinary tract development (18). Indeed, in 2 mutant embryos at E11.5, we could capture the initial process of extra budding from the main stem of the ureter, a site where buds normally never emerge. The mechanism for limiting the site of the budding to the tip of the branching ureter in wild-type animals has heretofore been largely unknown. Although the tightly regulated expression pattern of c-ret and its ligand GDNF may be part of the mechanism to specify the site of branching, both c-ret and GDNF are expressed surprisingly ...

Ectopic ureter (or ureteral ectopia) is a medical condition where the ureter, rather than terminating at the urinary bladder, terminates at a different site. In males this site is usually the urethra, in females this is usually the urethra or vagina. It can be associated with renal dysplasia, frequent urinary tract infections, and urinary incontinence (usually continuous drip incontinence). Ectopic ureters are found in 1 of every 2000-4000 patients, and can be difficult to diagnose, but are most often seen on CT scans. ...

Most of us are born with two ureters, one to drain the urine from each kidney into the bladder. But some babies are born with 2 ureters that drain a single kidney. In these cases, one ureter drains the upper part of the kidney and the second ureter drains the lower part of the kidney. As long as they both enter the bladder, this extra ureter is usually not a problem.

Background: Aberrant methylation of genes is one of the most common epigenetic modifications involved in the development of urothelial carcinoma. However, it is unknown the predictive role of methylation to contralateral new upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU). We retrospectively investigated the predictive role of DNA methylation and other clinicopathological factors in the contralateral upper tract urothelial carcinoma (UTUC) recurrence after radical nephroureterectomy (RNU) in a large single-center cohort of patients.. Methods: In a retrospective design, methylation of 10 genes was analyzed on tumor specimens belonging to 664 consecutive patients treated by RNU for primary UTUC. Median follow-up was 48 mo (range: 3-144 mo). Gene methylation was accessed by methylation-sensitive polymerase chain reaction, and we calculated the methylation index (MI), a reflection of the extent of methylation. The log-rank test and Cox regression were used to identify ...

Upper tract urothelial carcinoma is a disease with rapidly changing management. Though rare, recent multi-institutional collaborations have allowed for study of its biology and treatment outcomes in greater detail than ever before. In coming years physicians treating ureteral cancers will have an expanded armamentarium of treatment options and better data on which to base treatment decisions. Currently there is exciting work underway both in terms of developmental therapies, including neoadjuvant chemotherapy, as well as improved prognostics allowing for better utilization of nephron-sparing approaches where applicable. We present a review of current management techniques and the data on which to base management choices for surgeons treating upper tract urothelial carcinoma. The ultimate goal is improving outcomes for patients; with recent developments and current work in the field, there is reason to be optimistic for the future in this rare, challenging disease.. ...

There was exciting news in the field of bladder cancer treatment at the 2018 Genitourinary Cancers Symposium, held in San Francisco, CA. Speaking from the meeting, Alison Birtle, MRCP, FRCR, MD, of Lancashire Teaching Hospitals NHS Foundation Trust, Preston, UK, discusses the findings from the POUT trial (NCT01993979), a Phase III randomized study that determined the efficacy and the safety of adjuvant chemotherapy following radical nephroureterectomy, as well as its effect on the quality of life, for patients with upper tract urothelial carcinoma (UTUC). With such promising data from the POUT trial, Dr Birtle expresses her hopes of adjuvant chemotherapy becoming the standard of care for patients with UTUC.

Objectives: The main challenge of laparoscopic nephroureterectomy is the management of distal ureter, which also will have an important repercussion in the oncological outcome of many cases. We present our experience in such aspect, considering that we performed the last five laparoscopic nephroureterectomies in forced Trendelemburg position, resulting in a more comfortable and safe management of the distal ureter. Methods: Between August and December 2006 we performed five purely laparoscopic nephroureterectomies with bladder cuff positioning the patient in forced Trendelemburg, a position similar to that of laparoscopic radical cystectomy or prostatectomy. Results: Mean surgical time was 182 minutes (170-210). Mean blood loss was 100 cc and no patient required transfusion. Mean hospital stay was four days. ...
The ureter may be absent entirely, or it may end blindly after extending only part of the way to the flank. These anomalies are caused during embryologic development, by failure of the ureteral bud to form from the mesonephric duct or by an arrest in its development before it comes in contact with the metanephric blastema. The genetic determinants of ureteral bud development and the causes of bud abnormalities are being elucidated and it is known that GDNF signaling via the RET receptor is generally required (Michos et al, 2010). In any event, the end result of an atretic ureteral bud is an absent or multicystic dysplastic kidney. The multicystic kidney is usually unilateral and asymptomatic and of no clinical significance. In rare cases, it can be associated with hypertension, infection, or tumor. Contralateral vesicoureteral reflux is common, and many clinicians recommend a voiding cystourethrogram as part of the initial workup. There has been a concern about the risk of malignancy in these ...

Presentation Authors: Kevin K Yang*, Ziho Lee, Aeen M Asghar, Randall A Lee, David M Strauss, Philadelphia, PA, Toshiyuki China, Tokyo, Japan, Michael J Metro, Daniel D Eun, Philadelphia, PA. Introduction: Primary excision of a ureteral stricture followed by ureteroureterostomy (U-U) has been well reported for focal mid- and proximal ureteral strictures. For a distal ureteral stricture, U-U was historically less favored due to limited visualization in the deep pelvis and concerns about periureteral blood supply. We believe that the enhanced optics and fine dexterity of the robotic platform allow distal U-Us to be technically viable. We present our series of distal U-Us for focal distal ureteral strictures in conjunction with a representative case.. Methods: In a prospectively maintained ureteral reconstruction database, we followed patients who underwent a robotic-assisted laparoscopic distal U-U for a focal distal ureteral stricture. The latter was defined as any stricture at or distal to the ...

Osr1 is the earliest marker of the intermediate mesoderm, which will form the gonads and kidneys. This expression is not essential for the formation of intermediate mesoderm but for the differentiation towards renal and gonadal structures.[14][15] Osr1 acts upstream of and causes expression of the transcription factors Lhx1, Pax2 and Wt1 which are involved in early urogenital development.[14] In normal kidney development, activation of the Pax2-Eya1-Hox11 complex and subsequent activation of Six2 and Gdnf expression allows for branching of the ureteric bud and maintenance of the nephron-forming cap mesenchyme.[16] Six2 maintains the self-renewing state of the cap mesenchyme.[17] and Gdnf, via the Gdnf-Ret signalling pathway, is required for attraction and branching of the growing ureteric bud.[18] Within the developing kidney, Osr1 expressing cells will become mesangial cells, pericytes, ureteric smooth muscle and the kidney capsule. The cell types that Osr1 expressing cells will differentiate ...
Apoptosis has been linked in several systems to connecting discrete epithelial structures. We determined whether apoptotic remodeling may play a role in luminal interconnection by examining cleavage of the proapoptotic enzyme caspase 3, an early event in the apoptotic program, using antibodies specific to the cleaved apoptosis promoting protein, and through terminal deoxynucleotidyl transferase-mediated digoxigenin-deoxyuridine nick-end labeling (TUNEL) of fragmented DNA, a late event in apoptosis.24 Whereas an occasional scattered apoptotic cell was detected (arrows in Figure 3, D1 and D2), none were observed specifically within the distal segment of the RV derivative or the adjacent ureteric epithelium. Thus, apoptosis is unlikely to play a significant role in epithelial interconnection in the renal system.. To look more closely at the cellular organization of the distal RV derivative preceding interconnection, we immunostained tissue sections with antibodies recognizing key components ...

The kidneys are exposed to hypoxic conditions during development. Hypoxia-inducible factor (HIF), an important mediator of the response to hypoxia, is believed to have an important role in development. However, the relationship between HIF and branching morphogenesis has not been elucidated clearly. In this study, we examined whether HIF regulates kidney development. We harvested kidneys from day 13 rat embryos (E13K5) and cultured the organs under normoxic (20% 02/5% CO2) or hypoxic (5% 02/5% CO2) conditions. We evaluated the kidneys based on morphology and gene expression. El3K5 cultured under hypoxic conditions had significantly more ureteric bud (UB) branching than the E13Ks cultured under normoxic conditions. In addition, the mRNA levels of GDNF and GDNF receptor (GFR-alpha l), increased under hypoxic conditions in E13K5. When we cultured E13Ks( with the HIF-1 alpha inhibitor digoxin or with siRNA targeting HIF-l alpha under hypoxic conditions, we did not observe increased UB branching. In ...

Introduction: A number of randomized trials and meta-analysis in patients who underwent ureteroscopic stone removal investigated the effects of placing a ureteral stent at the end of the procedure on complication rates. However, none of these investigates the stone diameter and its possible influence on complication rates and, as such, if it should be considered a possible variable in the decision process of placing or not a ureteral stent. Materials and methods: A bibliographic search covering the period from January 1990 to March 2012 was conducted in PubMed, MEDLINE and EMBASE. This analysis is based on the fifteen remaining studies which fulfilled the predefined inclusion criteria. All statistical evaluations were performed using SAS version 9.2. and by RevMan 5.0. Results: A total of 1,416 patients were included. All the studies were published after 2000.

A ureterocele is when part of a ureter right near the bladder becomes larger and bulges. This happens because the ureters opening into the bladder is too small and blocks urine flow.
During the fifth week of gestation, the mesonephric duct develops an outpouching, the ureteric bud, near its attachment to the cloaca. This bud, also called the metanephrogenic diverticulum, grows posteriorly and towards the head of the embryo. The elongated stalk of the ureteric bud, called the metanephric duct, later forms the ureter. As the cranial end of the bud extends into the intermediate mesoderm, it undergoes a series of branchings to form the collecting duct system of the kidney. It also forms the major and minor calyces and the renal pelvis. The portion of undifferentiated intermediate mesoderm in contact with the tips of the branching ureteric bud is known as the metanephrogenic blastema. Signals released from the ureteric bud induce the differentiation of the metanephrogenic blastema into the renal tubules. As the renal tubules grow, they come into contact and join with connecting tubules of the collecting duct system, forming a continuous passage for flow from the renal tubule to ...
Megaureter is a ureter that is much wider than normal. A ureter that is wider than 10 mm (3/8 inch) is a megaureter. A megaureter may not drain urine normally. This can lead to infections and kidney damage.
Reflux nephropathy is kidney damage (nephropathy) due to urine flowing backward (reflux) from the bladder toward the kidneys; the latter is called vesicoureteral reflux (VUR). Longstanding VUR can result in small and scarred kidneys during the first five years of life in affected children. The end results of reflux nephropathy can include high blood pressure, excessive protein loss in the urine, and eventually kidney failure. ...
