The surge of technological advancements has changed the way we treat diseases. In the realm of nephron sparing surgery there is a raging debate on the role of ischemia in the preservation of renal function. We set about discussing this issue by conducting a literature search of pertinent articles of interest. Our narrative synthesis of these articles sheds light on the matter as well as discusses recent innovation that modifies or even eliminates the use of mechanical ischemia in renal surgery.. ...

BACKGROUND: Living kidney donor selection has become more liberal with acceptation of hypertensive donors. Here, we evaluate short-term and 1- and 5-year renal outcome of living kidney donors with preexistent hypertension. METHODS: We compared outcome of hypertensive donors by gender, age, and body mass index with matched control donors. Hypertension was defined as predonation antihypertensive drug use. All donors had glomerular filtration rate (I-iothalamate) and effective renal plasma flow (I-hippuran) measured 4 months before and 2 months after donation. A subset of donors had serum creatinine measured 1 year after donation or a renal function measurement 5 years after donation. RESULTS: Included were 47 hypertensive donors and 94 control donors (both 53% male; mean age, 57±7 years; and body mass index, 28±4 kg/m). Pre- and early postdonation, systolic blood pressure, and mean arterial pressure were significantly higher in hypertensive donors. Control donors showed a rise in diastolic blood

The effect of short-term (mean 2.4 months), low-dose (5 mg/kg) cyclosporin A (CyA) on renal function and blood pressure was studied in eight patients with psoriasis. Studies were undertaken before, during and after treatment. Glomerular filtration rate (GFR) post-treatment was significantly higher than pretreatment or during treatment (pre, 119 +/- 7; during, 113 +/- 9; post, 133 +/- 11 ml/min per 1.73 m2; pre vs. during, NS; during vs. post, P , 0.01; pre vs. post, P , 0.05); effective renal plasma flow (ERPF) was unchanged (pre, 515 +/- 38; during, 485 +/- 49; post, 560 +/- 45 ml/min per 1.73 m2). There was no change in the urinary excretion of either albumin or the enzymes N-acetyl-glucosaminidase, lactate dehydrogenase, alanine aminopeptidase and alkaline phosphatase. There was a decrease in exchangeable sodium which persisted post-treatment (pre, 56 +/- 3; during, 49 +/- 3; post, 49 +/- 3 mmol/kg LBM; pre vs. during, P = 0.07; during vs. post, NS; pre vs. post, P = 0.06). Blood pressure ...

The effects of a stressful environmental stimulus (air stress) on mean arterial pressure, heart rate, renal sympathetic nerve activity, and renal function were studied in conscious deoxycorticosterone acetate-sodium chloride (DOCA-NaCl) hypertensive rats, sham DOCA-NaCl normotensive rats, and DOCA-NaCl rats with renal denervation. In conscious DOCA-NaCl hypertensive rats, air stress decreased urine flow rate [36% from 17.9 +/- 3.0 microliter X min-1 X 100 g body wt-1 (BW)], urinary sodium excretion (39% from 3.1 +/- 0.5 microeq X min-1 X 100 g BW-1), fractional water excretion (24% from 4.72 +/- 1.00%), and fractional sodium excretion (28% from 5.72 +/- 1.08%) and increased renal sympathetic nerve activity (94% from 8.3 +/- 0.6 integrator resets/min), but no changes occurred in glomerular filtration rate (-15% from 0.40 +/- 0.06 ml X min-1 X 100 g BW-1) or effective renal plasma flow (-7% from 2.50 +/- 0.53 ml X min-1 X 100 g BW-1). Air stress had no effect on these measures in conscious sham ...

The angiotensin-II analogue sar1-ala8- Summary angiotensin II (Saralasin) was administered intravenously in different doses to two patients with unilateral renovascular hypertension. On a sodium intake of 100 meq., infusion of the analogue resulted in a decrease in blood-pressure by 10-20 mm. Hg, a striking sodium retention, and a fall in ... read more effective renal plasma flow. In one patient the analogue infusion was repeated after sodium depletion : blood-pressure fell to normal within 10 minutes. After corrective surgery plasma-renin activity returned to normal within 1 day, but in both patients blood-pressure reached normal values only 2-3 weeks later. These results suggest that two mechanisms are acting jointly in the maintenance of the hypertension in these two cases of unilateral renal-artery stenosis. show less ...

The purpose of the present study was to develop a controllable experimental model in the dog that would consistently and predictably produce a malignant hypertensive crisis, and to determine the sequential changes in renal function, salt and water balance, and hormones that are involved in the transition from benign to accelerated hypertension. Norepinephrine (NE) was infused continuously into the renal artery of unilaterally nephrectomized dogs that were maintained on 50 mEq sodium/day. The infusion rate of NE was increased each day according to the following schedule: 0.05, 0.1, 0.2, 0.3, 0.4, and 0.5 microgram/kg/min. During the first 4 to 5 days of intrarenal NE infusion, there was a progressive decrease in glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), and increases in plasma renin activity (PRA), mean arterial pressure (MAP), and filtration fraction. At the end of this period of benign hypertension, MAP had risen from a control value of 91 +/- 4 to 132 +/- 8 mm ...

1. The effects of prolonged high sodium intake (duration 3 months) and meclofenamate were studied in two groups of male spontaneously hypertensive (SH) rats.. 2. Group 1 (eight rats) received 1% NaCl in water and served as controls, and group 2 received 1% NaCl in water plus meclofenamate (3·5-4·0 mg daily).. 3. Group 2 rats developed higher arterial pressure, renal vascular resistance and left ventricular weight and greater renal histological changes, with lower effective renal plasma flow, renal blood flow and glomerular filtration rate, than group 1. No differences were observed between the two groups in heart rate, body weight, fluid intake, urine volume, UNaV, UKV and right ventricular weight.. 4. The results suggest that the combination of high sodium intake and meclofenamate exerts a greater damaging effect on the arterial pressure and renal function of SH rats than salt alone.. ...

GSK1349572 is an integrase inhibitor being developed for the treatment of human immunodeficiency virus (HIV)-1 infection by GlaxoSmithKline (GSK) on behalf of Shionogi-ViiV Healthcare LLC. In healthy subjects and in dose-ranging clinical trials of GSK1349572, subjects showed a small, reversible increase in serum creatinine concentrations as compared to the control groups; this occurred early during study drug administration and did not progress over time. In vitro data demonstrate that GSK1349572 inhibits the organic cation transporter (OCT2), which mediates the tubular secretion of creatinine; drugs such as cimetidine with similar effects on OCT2 lead to a nonpathological increase in creatinine with no effect on glomerular filtration rate (GFR). The current study is designed to confirm the mechanism behind the increase in serum creatinine observed during GSK1349572 therapy; specifically, the study will determine whether GSK1349572 has any effect on GFR or effective renal plasma flow. Absent ...

Central distribution of body fat is associated with a higher risk of renal disease, but whether it is the distribution pattern or the overall excess weight that underlies this association is not well understood. Here, we studied the association between waist-to-hip ratio (WHR), which reflects central adiposity, and renal hemodynamics in 315 healthy persons with a mean body mass index (BMI) of 24.9 kg/m2 and a mean 125I-iothalamate GFR of 109 ml/min per 1.73 m2. In multivariate analyses, WHR was associated with lower GFR, lower effective renal plasma flow, and higher filtration fraction, even after adjustment for sex, age, mean arterial pressure, and BMI. Multivariate models produced similar results regardless of whether the hemodynamic measures were indexed to body surface area. Thus, these results suggest that central body fat distribution, independent of BMI, is associated with an unfavorable pattern of renal hemodynamic measures that could underlie the increased renal risk reported in ...

The mechanism of action of prazosin hydrochloride, a new antihypertensive agent was studied in 14 patients with essential hypertension. Mean supine blood pressure for the group fell from 148/102 +/- 3/2 (SE) mm Hg at baseline to 139/91 +/- 5/4 after eight weeks of therapy (P less than 0.05). No significant postural hypotension was noted in the patients who responded to therapy. Glomerular filtration rate (endogenous creatinine or inulin clearance) and effective renal plasma flow (PAH clearance) remained unchanged during therapy as did supine and stimulated peripheral plasma renin activity. Cardiac output did not change significantly although plasma volume increased in ten out of 12 patients in whom it was measured (P less than 0.025). Among the patients whose mean blood pressure fell 10 mm Hg or more, peripheral vascular resistance fell significantly (P less than 0.025), and the change in plasma volume was not statistically significant. Among the patients whose mean blood pressure changed less ...

In the physiology of the kidney, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1.1 L/min in a 70-kg adult male. RBF is closely related to renal plasma flow (RPF), which is the volume of blood plasma delivered to the kidneys per unit time. While the terms generally apply to arterial blood delivered to the kidneys, both RBF and RPF can be used to quantify the volume of venous blood exiting the kidneys per unit time. In this context, the terms are commonly given subscripts to refer to arterial or venous blood or plasma flow, as in RBFa, RBFv, RPFa, and RPFv. Physiologically, however, the differences in these values are negligible so that arterial flow and venous flow are often assumed equal. Renal plasma flow is the volume of plasma that reaches the kidneys per unit time. Renal plasma flow is given by the Fick principle: R P F = U x V P a − P v {\displaystyle RPF={\frac ...

Normal aging is accompanied by renal functional and morphological deterioration and dietetic manipulation has been used to delay this age-related decline. We examined the effects of chronic administration of diets containing 5% lipid-enriched diet (LD, w/w) on renal function of rats at different ages. Three types of LD were tested: canola oil, fish oil and butter. Mean systemic tail-cuff blood pressure and glycemia remained within the normal range whatever the age and the diet of the animals. Proteinuria began to rise from the 8th month in the groups ingesting LD, while in the control group it increased significantly (above 10 mg/24 h) only after the 10th month. With age, a significant and progressive decline in glomerular filtration rate (GFR) and renal plasma flow was observed in the LD groups but after 6 months of lipid supplementation, the decline in these parameters was more marked in the butter and fish oil groups. By the 18th month, the lowest GFR level was observed in the group ingesting ...

1. To elucidate the mechanisms by which cyclosporin A diminishes proteinuria, we studied 20 patients with severe nephrotic syndrome. Biopsy-established pathologies included minimal change disease (n = 5), membranous glomerulopathy (n = 6), membranoproliferative glomerulonephritis (n = 5) and focal segmental glomerulosclerosis (n = 4). Before, at the end of a 90 day course of cyclosporin A, and finally 1 month after stopping cyclosporin A we determined 24 h protein excretion. Measurements of glomerular filtration rate, effective renal plasma flow, fractional clearance rates of albumin and immunoglobulins with different charges and the transglomerular sieving of uncharged dextrans of broad size distribution were used to study the effects of cyclosporin A on renal perfusion and the glomerular filtration barrier. The findings were analysed with a theoretical model of solute transport.. 2. Among the different forms of glomerulopathy the response to low-dose cyclosporin A (trough levels 32.0-36.9 ...
