BACKGROUND: New surgical techniques for nephrectomy mainly related to early diagnosis made possible by advances in imaging studies have been developed in recent decades. However, postoperative renal dysfunction is a constant concern because of the major problems faced by healthcare services and by the patients themselves. To assess risk factors for developing acute renal failure (ARF) in patients submitted to nephrectomy in a university hospital. METHODS: Seventy-seven patients submitted to nephrectomy for benign and malignant diseases in a university hospital were evaluated in respect to preoperative and postoperative creatinine clearance...

Objective To compare the surgical outcomes between resection and enucleation in robot-assisted laparoscopic partial nephrectomy (RAPN) based on the Surface-Intermediate-Base margin score (SIB score). Patients and Methods This study included 282 patients who underwent RAPN between 2014 and 2016. SIB score was macroscopically evaluated immediately after the surgery. We divided the patients into the following two groups: enucleation (SIB score, 1-2) and resection (SIB score, 3-5). To minimize selection bias between the two surgical methods, patient variables were adjusted by 1:1 propensity score matching...

Reninoma is a rare form of secondary hypertension. The present study reported a case of reninoma that coexisted with an adrenal adenoma in a young female with secondary hypertension during pregnancy. The patient, a 31-year-old female exhibiting hypertension for >1 year, developed a mass in the right adrenal gland, which was detected by an ultrasound scan in the 33rd gestational week. In addition, a well-defined solid mass on the left kidney was detected by a magnetic resonance imaging scan1 month subsequent to the termination of the pregnancy...

INTRODUCTION: We aimed to assess the effect of previous abdominal surgery on perioperative outcomes in patients undergoing transperitoneal laparoscopic partial (LPN) or radical (LRN) nephrectomy for renal masses. METHODS: We retrospectively reviewed all cases of LPN and LRN for renal masses at our institution between 2008 and 2014. Patients were divided in two groups, those with and without prior abdominal surgery. Four perioperative outcomes were compared, namely, operative time (OT), estimated blood loss (EBL), length of stay (LOS), and 30-days complications rate...

Patient outcomes for retroperitoneal laparoscopic radical nephrectomy (RLRN) in adults on peritoneal dialysis (PD) have not been described in the literature. This is the first series on the successful application of RLRN for renal cell carcinoma (RCC) among adults with end-stage renal disease (ESRD) on PD. In our series of 5 patients, all were able to promptly resume PD, no wound complications were noted at postoperative visits, and no evidence of recurrence was identified on surveillance imaging at follow-up...

A 67-year-old female was hospitalized with back pain. Computed tomography (CT) incidentally revealed a tumor in her left kidney tumor (33 mm) and bilateral breast tumors. She underwent a breast biopsy and was diagnosed with breast cancer (invasive lobular cancer, cT2N0M0). The renal tumor was suspected to be clear cell carcinoma, cT1aN0M0, based on contrast-enhanced CT. Surgery was considered necessary for both the breast cancer and renal tumor. First, laparoscopic radical nephrectomy was performed for the renal tumor...

BACKGROUND: Renal transplantation is the most successful therapy for improving survival and quality of life for end-stage renal disease (ESRD). Living donor kidney transplantation (LDKTx) has been used as an alternative to reduce the stay on the waiting list of patients with ESRD. Laparoscopic donor nephrectomy (LDN) has become the standard procedure for LDKTx. OBJECTIVE: This study aims to describe evolution of surgical technique with LDN at our institute. MATERIALS AND METHODS: We retrospectively analyzed our experience with LDN performed from January, 2003 to November, 2016, focusing on describing modifications of the surgical technique and devices made during those years...

Peritoneal dialysis (PD) is an effective renal replacement therapy for the treatment of end-stage renal disease. Patients on PD undergoing abdominal open surgery often fail to resume PD. Laparoscopic surgery has recently become a serious alternative to open surgery in patients on PD to treat different abdominal pathologies. However, only a few studies have reported successful procedures without Tenckhoff catheter removal. The aim of this review is to describe how a laparoscopic technique can allow PD patients to deal with abdominal surgery without shifting to hemodialysis...

INTRODUCTION: We aimed to develop a scoring system to quantify the distance between the renal hilum and renal tumour, termed the modified C index (m-CI), and to predict renal functional loss (RFL) following laparoscopic partial nephrectomy (LPN). METHODS: The m-CI was measured by using computed tomography in 113 patients who underwent LPN between May 2003 and June 2014. The RFL following LPN was calculated by examining the estimated glomerular filtration rate (eGFR) and radioisotope renography one year postoperatively...

OBJECTIVE: To characterize changes in surgical assistance patterns over time for commonly performed urologic operations. METHODS: This study used the Medicare Physician/Supplier Procedure Summary Master File to identify cases performed by urologists from 2003-2014. CPT modifiers were used to identify operations assisted by second surgeons and advanced practice providers (APPs). Rates were reported annually for six common urologic operations and average annual rates of change were determined using least squares regression and tested using t-tests (α=0...

PURPOSE: Routine evaluation of kidney donors occasionally reveals an incidental renal mass with an otherwise satisfactory kidney function. The use of such a kidney with an enhancing mass for transplantation is a matter of debate owing to a possible risk of transmission of donor malignancies. We report our experience of kidney transplants from donors with renal cell carcinoma, after ex vivo resection of the renal mass. METHODS: Two women aged 44 and 56 years were diagnosed with enhancing renal masses measuring 0...

A primipara at term was admitted to the labour ward with spontaneously emerged severe abdominal pain in the right flank and kidney. The patient was not known with any obstetric or urologic conditions. An acute caesarian section was performed due to the pain and pathological results of the cardiotocography, and a healthy child was delivered. During surgery, a haematoma was detected in the retroperitoneal space. A computed tomography (CT) of abdomen showed a Bosniak type IV tumour with surrounding haematoma in the kidney...

Internal herniation following laparoscopic surgery is rare. We present a case of small bowel obstruction secondary to internal herniation in a 76-year-old male patient. Presentation was on postoperative day 28 following transperitoneal laparoscopic radical left nephrectomy for suspected renal carcinoma. The herniation was through a defect in the large bowel mesentery identified at exploratory laparotomy. To date, 10 cases of internal herniation following laparoscopic nephrectomy have been described in the literature...

OBJECTIVE: The present study asks whether intraoperative principles are shared among faculty in a single residency program and explores how surgeons' individual thresholds between principles and preferences might influence assessment. BACKGROUND: Surgical education continues to face significant challenges in the implementation of intraoperative assessment. Competency-based medical education assumes the possibility of a shared standard of competence, but intersurgeon variation is prevalent and, at times, valued in surgical education...

Background: Multiple renal artery (MRA) kidneys represent a special challenge for surgeons, during both donor nephrectomy and renal transplantation. AIMS: This study aims to evaluate both donors and recipients outcomes of laparoscopically procured dual renal artery (DRA) kidneys. Patients and Methods: We reviewed the medical records of all living kidney donors who underwent laparoscopic donor nephrectomy between April 2009 and December 2014, and their recipients. Operative details and immediate outcomes of both donors and recipients of DRA kidneys were compared to those of donors and recipients of single renal artery (SRA) kidneys...

INTRODUCTION: Robot-assisted kidney harvesting from living donors is feasible and safe. We report the results of a mono-centric experience relative to 98 consecutive robotic nephrectomies with emphasis on global donor complications. MATERIALS AND METHODS: This is a retrospective cohort study. Donors underwent robot-assisted kidney harvesting. The preferred kidney was the left one even in the presence of vascular anomalies. In the first cases we used a robotic hand-assisted technique, then the totally robotic technique, and finally the modified totally robot-assisted technique...

Renal artery vasospasm can be a troublesome complication during robot-assisted laparoscopic partial nephrectomy. Urologists performing this procedure, especially if utilizing selective arterial vascular microdissection, should be aware of using papaverine for both prevention and treatment of renal artery vasospasm. We present a 33-year-old male who developed severe renal artery vasospasm just with hilar dissection causing the kidney to become ischemic. Papaverine was topically applied on the renal arteries resulting in vasodilation and reperfusion of the kidney...

Laparoscopic surgery is an evolving surgical modality in children, which has been applied to increasingly more complex surgeries and patients, including patients with renal insufficiency. These patients are particularly susceptible to the challenges that laparoscopy imposes on their altered physiology, leading to marked electrolyte disturbances, including metabolic acidosis and hyperkalemia. Hyperkalemia has the potential for marked impairment of cardiac conduction. We report 2 cases where significant, potentially lethal hyperkalemia developed during laparoscopic nephrectomy in adolescents with renal insufficiency...
