Introduction: The surgical standard of care for favorably located, small renal tumors is partial nephrectomy. As the incidence of renal cell carcinoma (RCC) and earlier incidental detection of small kidney masses has steadily risen over the past twenty years, minimally-invasive management of these lesions has become more common. We report our single institution experience with hand-assisted laparoscopic partial nephrectomy (HALPN) as compared with traditional open partial nephrectomy (OPN ...
MEYER, Fernando et al. Early outcomes of laparoscopic donor nephrectomy with multiple renal arteries. Int. braz j urol. [online]. 2012, vol.38, n.4, pp.496-503. ISSN 1677-6119. http://dx.doi.org/10.1590/S1677-55382012000400009.. PURPOSE: We evaluated our experience with laparoscopic donor nephrectomy in patients with multiple renal arteries, comparing operative outcomes and early graft function with patients with a single renal artery. MATERIALS AND METHODS: From January 2003 to February 2009, 130 patients underwent laparoscopic donor nephrectomy at our institution, 108 (83%) with a single renal artery and 22 (17%) with multiple arteries. Donor and recipient outcomes for single artery and multiple arteries allografts were compared. RESULTS: The LDN operative time was similar between the single artery and multiple arteries groups (162 vs 163 min, respectively, p = 0.87). Allografts with multiple arteries had significantly longer warm ischemia time (3.9 vs 4.9 min, p = 0.05) and cold ischemia time ...
TITLE: A Review of Perioperative Complications In 120 Consecutive Community Based Laparoscopic Donor Nephrectomies. INTRODUCTION: Throughout the mid 1990s and early 2000s numerous university programs compared perioperative complications in laparoscopic donor to the gold standard open technique in order to validate the emerging standard of care for nephrectomies. As innovation becomes the norm, an important question yet to be answered in the literature is how the complication rate at a community hospital performing donor nephrectomies compares to the larger academic centers now that laparoscopic nephrectomies are universally performed.. METHODS: All the charts from patients undergoing laparoscopic nephrectomies between January 1, 2006 and December 31, 2008 were reviewed. The examined outcomes were operative time, estimated blood loss, intra-and post operative complications, and length of hospital stay. The results were stratified in order to compare them with national figures using statistical ...
Right donor nephrectomy,especially when conducted laparoscopically,has not been accepted by most transplant surgeons because of the consequent short right renal vein and the possible increased incidence of venous thrombosis and other surgical complications. We have evaluated our outcomes of Hand Assisted Laparoscopic Donor nephrectomy (HALD) and we compared between right and left donor nephrectomy.HALD has been performed at our institution since December,1999.Through May 2014, a total of 1,500 HALD procedures have been performed.We decided to perform right donor nephrectomy when there is complex left renal vascular anatomy, the right kidney has a benign pathology, the right kidney is smaller than the left , 20% or the function of the right kidney is less than the left by , 20%.Right Donor Nephrectomy (RDN) was performed in 272 patients and Left Donor Nephrectomy (LDN) was performed in 1,228 patients. Mean donor age was 40.5(18.8-66.9) for RDN group and 40.9(18.5-68.5) for LDN group, BMI was ...

To assess whether routine postoperative chest radiography (CXR) is required after open nephrectomy for the detection and possible management of a pneumothorax. It has become the standard of care by many urologists to obtain routine postoperative CXRs after open nephrectomy to assess for the presence of a pneumothorax. However, at our institution, very few patients have developed a pneumothorax postoperatively, and, furthermore, the CXR findings almost never affected the clinical management. Methods. Retrospective data were collected on the last 150 open nephrectomies performed by two urologists at our institution. All laparoscopic nephrectomies and thoracoabdominal nephrectomies were excluded from analysis. Results. A total of 150 patients underwent open ...

Partial nephrectomy is most often performed through a flank incision. Whilst keyhole surgery is suitable for total nephrectomy, for technical reasons it is far more difficult to perform a partial nephrectomy via a keyhole approach. Even in the most experienced hands, laparoscopic partial nephrectomy is associated with a higher complication rate than open partial nephrectomy.. After the kidney is exposed, its blood supply is temporarily interrupted by means of specially designed clamps. The kidney is then bathed in ice. This preserves kidney function whilst its blood supply is temporarily halted. This cannot be done via a laparoscopic approach, resulting in a higher risk of losing functioning kidney cells. Once the kidney has been cooled, the cancer is then "carved" out of the kidney and specimens are taken from the kidney for immediate analysis by a pathologist (frozen section analysis) to ensure that no cancer has been left behind. The kidney is then repaired and the blood supply into the ...

The purpose of this study is presenting a method to predict the presence of an open urinary tract and the position of the opening in laparoscopic partial nephrectomy from three dimensional (3D) computed tomography (CT) images by using novel image segmentation and visualization techniques. From CT images of patients who underwent laparoscopic partial nephrectomy, 3D regions of the kidney, urinary tract, and tumor were segmented. For each patient, multiple virtual resection planes of the kidney with different surgical margins (1 mm to 5 mm, every 1 mm) were generated and the presence of an open urinary tract and the position of the opening were predicted from the images. We compared the predictions with actual operations in 5 cases by using recorded video of the operations and operative notes. In terms of the presence of an open urinary tract, agreement of the predictions and the intraoperative results was obtained in all patients. The expected positions of the openings were close to those in the actual

Objectives: Based on imaging features, nephrometry scoring systems have been conceived to create a standardized and reproducible way to characterize renal tumor anatomy. However, less is known about which of these individual measures are important with regard to clinically relevant perioperative outcomes such as ischemia time (IT), estimated blood loss (EBL), length of hospital stay (LOS), and change in estimated glomerular filtration rate (eGFR) after robotic partial nephrectomy (PN). We aimed to assess the utility of the RENAL and PADUA scores, their subscales, and C-index for predicting these outcomes. Materials and Methods: We analyzed imaging studies from 283 patients who underwent robotic PN between 2008 and 2014 to assign nephrometry scores (NS): PADUA, RENAL and C-index. Univariate linear regression was used to assess whether the NS or any of their subscales were associated with EBL or IT. Multivariable linear regression and linear regression models were created to assess LOS and eGFR. ...
BACKGROUND: The two major life-threatening complications associated with laparoscopic live donor nephrectomy are sudden severe bleeding and intestinal injury. A combined technique-hand-assisted and retroperitoneoscopic (HARS)-reduces the risk of these life-threatening complications. In this study, we report on our experience from the first 75 consecutive HARS operations. METHODS: The data has been collected prospectively according to intention to treat and includes all consecutive donors operated with the HARS technique. Warm ischemia time, operating time, and blood loss were recorded. Complications, convalescence, and allograft outcome were followed postoperatively with a mean follow-up of 701 (range 60-1438) days. RESULTS: The mean operating time was 138 (range 85-260) minutes and the mean warm ischemia time 175 (85-510) seconds. The operative time was significantly longer in male donors. The mean bleeding was 176 (50-700) ml. There were no conversions to open surgery. Major complications ...

Sirs,. We read with great interest the study by Neuhaus et al. reporting on live kidney donors (that had donated by open nephrectomy) and their high degree of satisfaction with the predonation decision-making process, along with improved postdonation relationships with their partners and the recipient children [1].. One question that this valuable and insightful study was unable to answer was whether the recent introduction of the less invasive laparoscopic technique (which has rapidly become the standard of care) [2, 3] has had any additional effects on the decision-making process and postoperative family dynamics and quality of life of those donating a kidney to a pediatric recipient. Interestingly, in adult-to-adult live donor kidney transplantation, several studies have demonstrated that laparoscopic live donor nephrectomy does not only significantly decrease postoperative morbidity [4], but may therefore also have contributed to the steady increase of live donor kidney transplants... ...

Technical considerations: The study included 506 patients, mean age of 63.3 years, with histologically proven benign renal lesions originating from 5 European centers. Retrospective data from each hospital were retrieved and merged into a common database for analyses. OS, American Society of Anesthesiology score, and renal functions were measured in relation to surgical technique. The Mann-Witney U-test, the paired t-test, and Coxs multivariate analysis were used.Patients treated with radical nephrectomy had significantly reduced renal function postoperatively compared with nephron sparing surgery (NSS). OS was significantly reduced after radical nephrectomy compared with NSS (P = .012), a survival difference that remained ...
TY - JOUR. T1 - Robotic Partial Nephrectomy for a Peripheral Renal Tumor. AU - Cooper, Caleb A.. AU - Shum, Cheuk Fan. AU - Sundaram, Chandru. PY - 2018/5/1. Y1 - 2018/5/1. N2 - Partial nephrectomy (PN) is the preferred surgical treatment for T1 renal tumors whenever technically feasible. When properly performed, it allows preservation of nephron mass without compromising oncologic outcomes. This reduces the postoperative risk of renal insufficiency, which translates into better overall survival for the patients. PN can be technically challenging, because it requires the surgeon to complete the tasks of tumor excision, hemostasis and renorrhaphy, all within an ischemic time of preferably below 30 minutes. The surgeon needs to avoid violating the tumor margins while leaving behind the maximal parenchymal volume at the same time. Variations such as zero ischemia, early unclamping, and selective clamping have been developed in an attempt to reduce the negative impact of renal ischemia, but ...
Renal cell carcinoma (RCC) is a tumor with clinically apparent immunologic phenomena, such as response to immunotherapies (interferon, interleukin-2, immune cellular therapy etc), spontaneous regression, and sometimes indolent behaviour. Nephrectomy itself influences the prognosis of advanced RCC patients as shown in 2 randomised trials, and could have an immune basis. We previously reported on the variability of clinical behaviour in advanced RCC patients who had not received systemic treatment after debulking nephrectomy (Debulking Nephrectomy Followed By A Watch And Wait Approach In Metastatic Renal Cell Carcinoma .Wong A, et al. Urol Oncol, in press). The clinical significance of this includes the avoidance of toxic systemic therapies after nephrectomy, or the possibility of using non-toxic vaccine approaches in metastatic patients after cytoreductive nephrectomy. In this research proposal we would like to analyse the immune related gene expression profile on nephrectomy tumor samples and ...

Chemical nephrectomy - What exactly is a partial nephrectomy? Kidney surgery. Partial nephrectomy refers to surgical removal of part of the kidney, usually because of a small tumor/abnormal growth of the kidney. A radical nephrectomy (total kidney removal) is done for larger tumors, or if the partial nephrectomy is not technically possible.
Objectives: To present our experience demonstrating the feasibility of off-clamp laparoscopic partial nephrectomy (LPN) for hilar tumors and evaluate intermediate oncologic and renal functional outcomes. Patients and Methods: A retrospective review of LPN cases in nine patients was performed. Hilar lesions were defined as renal cortical tumors in direct physical contact with the renal artery, vein, or both as identified on preoperative imaging and confirmed intraoperatively. Although the renal hilum vasculature was isolated for possible clamping if needed, tumor extirpation was performed off-clamp, eliminating warm ischemia time (WIT). The clinicopathologic parameters, perioperative course, complications, and long-term oncologic and renal functional outcomes were analyzed. Results: Nine patients underwent off-clamp LPN for complex hilar tumors. The mean age was 60.5 years, mean American Society of Anesthesiologists physical classification (ASA) score was 2, and mean BMI was 27.7kg/m(2). The mean tumor

To evaluate the role of three-dimensional (3D) reconstruction technique in renal function protection and ipsilateral parenchymal mass preserved after laparoscopic partial nephrectomy (LPN) in patients with complex renal tumor (R.E.N.A.L.score ≥ 8). A retrospective study enrolling 49 patients who suffered from RCC and underwent LPN at our center, from October 1, 2017, to October 31, 2018. Twenty-one patients (group A) underwent LPN with the 3D reconstruction technique before surgery, and the other 28 patients (group B) not. Preoperative and postoperative ipsilateral parenchymal mass volume and ipsilateral glomerular filtration rate (GFR) were analyzed 3-5 days prior and 3 months after PN. In order to compare the two groups, Mann-Whitney U test and chi-square tests were performed. The main limitation of this technique is that the volume calculations are partly performed manually. All patients median renal score was 10 with no difference between the two groups (P = 0.89), and the median tumor size of

Robotic partial nephrectomy appears to be a reasonable option for certain renal masses, provided that an experienced surgeon performs the procedure at a center that can manage postoperative complications, researchers concluded after conducting an analysis involving nearly 1,800 individuals. Participants had cT1a (n=1358), cT1b (n=379), or cT2a (n=41) renal masses. Investigators looked at how intra and postoperative outcomes in patients with cT2a masses compared to those with the other 2 mass types. Among the results:

INTRODUCTION & OBJECTIVES: Several reports demonstrated that nephron sparing surgery (NSS) better protects renal function relative to radical nephrectomy (RN). However, controversies exist whether NSS may also affect other-cause mortality (OCM). In the current study, we aimed to report the long term (more than 10 years) survival and functional outcomes of NSS vs. RN after accounting for clinical characteristics, comorbidities and individual patients cardiovascular risk. MATERIAL & METHODS: A multi-institutional collaboration among five European Tertiary Care Centers allowed collecting 1189 patients with a clinical T1a-T1b N0 M0 renal mass and treated between 1988 and 2004. Patients underwent RN (n=678, 57%) or NSS (n=511, 43%) and showed normal estimated glomerular filtration rates (eGFR) before surgery (defined as a pre-operative eGFR≥60ml/min/1.73m2). Descriptive, univariable and multivariable Cox regression analyses were used to predict the risk of OCM and chronic kidney disease (CKD, ...

Radical nephrectomy is the surgical procedure that involves removal of the entire kidney. This is usually required in case the kidney is affected with renal (kidney) cancer or if the kidney is severely damaged, or diseased, and fails to function normally.. This procedure might also be performed prior to a kidney transplantation to remove the diseased kidney and replace it with a healthy donor kidney.. The procedure may be performed using conventional open-type surgical method requiring large incision, or it can be done in the more modern way using a minimally invasive laparoscopic method. This minimally invasive (laparoscopic) method requires less number of incisions as well as the smaller-sized (keyhole) incisions. The main aim of the radical nephrectomy surgery is to remove the entire kidney while leaving the connecting tissue intact in case a future chance of transplanting a donor kidney arises.. ...

Hi wendyleigh -. I was first diagnosed with cancer in early March, and after getting a second and third opinion, I felt comfortable in my decision to have surgery as soon as I could get everything in order.. My Urologist and Surgeon first performed a cystocopy 2 weeks before the scheduled nephrectomy. The purpose of the cystocopy was to look closely at my bladder, right kidney as well as the right ureter. He suspected that cancer had invaded my right kidney along with the right ureter even though the CT Scan showed the tumor actually positioned on top of my right kidney. His suspicions were correct and this decision really helped him fully plan out the surgery well beforehand. I had my surgery on April 6. The two anesthesiologists for my surgery recommended an epidural, and I agreed, because a friend of mine has a cousin who worked at Memorial Sloan-Kettering Cancer Center in New York City and he said to ask for one as recovery right after a radical nephrectomy can be quite painful without ...

TY - JOUR. T1 - Minimally invasive heminephrectomy. T2 - Feasibility and outcomes. AU - Sobey, Steven. AU - Hakimi, A. Ari. AU - Faleck, David. AU - Ghavamian, Reza. PY - 2012/7/1. Y1 - 2012/7/1. N2 - Background and Purpose: Laparoscopic partial nephrectomy (LPN) has become a well-established treatment for patients with selected renal malignancies. As the skills of urologic laparoscopic surgeons have increased, more complex and larger tumors are now being approached in this manner. Laparoscopic heminephrectomy (LHN), defined as the resection of ,30% of a kidney, is described in this article. Standardized nephrometry scoring is used to grade tumor complexity; complications, renal function, and perioperative outcomes are discussed. Patients and Methods: One hundred forty-five patients underwent minimally invasive partial nephrectomy. Parameters studied included patient demographics, tumor characteristics, operative time, estimated blood loss (EBL), length of stay (LOS), clamp time, change in renal ...
In most cases in which preoperative imaging is optimized and the correct incision is used, partial nephrectomy can be performed in situ. Temporary arterial occlusion and regional hypothermia are often... more
Pre-transplant nephrectomy is performed to reduce risks to graft and recipient. The aims of this study were to evaluate (1) indications, surgical approach, and morbidity of native nephrectomy and (2) the effects of kidney removal on clinical and biological parameters. This study was designed as a single-center retrospective cohort study in which 49 consecutive patients with uni- or bilateral native nephrectomies were identified from a total of 126 consecutive graft recipients in our pediatric kidney transplantation database between 1992 and 2011. Demographic, clinical, and laboratory details were extracted from charts and electronic records, including operation reports and pre- and post-operative clinic notes. Of the 49 nephrectomized patients, 47% had anomalies of the kidneys and urinary tract, 22% had cystinosis, 12% had focal segmental glomerulosclerosis, and 6% had congenital nephrotic syndrome. Nephrectomy decisions were based on clinical judgment, taking physiological and psychosocial aspects into
