PURPOSE: Venous thromboembolism (VTE) is the leading cause of noncancer death following major cancer surgery. Current thromboprophylaxis guidelines do not address procedure-specific risk of venous thromboembolism for urological patients. This project was created to determine the risk and timing of VTE after major urological surgery and to evaluate if surgical procedure was an independent risk factor for VTE after adjusting for previously established risk factors. MATERIAL AND METHODS: The American College of Surgeons׳ National Surgical Quality Improvement Program was used to create a cohort of patients who received major abdominal or pelvic urologic surgery between 2006 and 2014...

We present a case of a patient who took part in a prospective sentinel lymph node (SN) study to investigate the drainage pattern from renal tumors. The patient was treated with laparoscopic radical nephrectomy (LRN), SN and non-SN lymph node dissection (LND) for a clinically node negative (cN0) left renal tumor of 6 cm (cT1b). Histopathological examination revealed a papillary type 2 pT1b renal cell carcinoma (RCC) with two para-aortic metastatic SNs (pN1). No adjuvant treatment was applied. The patient is free of disease at 63 months after surgery...

Background. A single dose of perioperative dexamethasone (8-10 mg) reportedly decreases postoperative nausea, vomiting, and pain but has not been widely used in laparoscopic donor nephrectomy (LDN). Methods. We performed a retrospective cohort study of living donors who underwent LDN between 2013 and 2015. Donors who received a lower dose (4-6 mg)  (n = 70) or a higher dose (8-14 mg) of dexamethasone (n = 100) were compared with 111 donors who did not receive dexamethasone (control). Outcomes and incidence of postoperative nausea, vomiting, and pain within 24 h after LDN were compared before and after propensity-score matching...

Introduction. The prevalence of obesity is increasing worldwide. Obesity can be determined by body mass index (BMI); however waist circumference (WC) is a better measure of central obesity. This study evaluates the outcome of laparoscopic nephrectomy on patients with an abnormal WC. Methods. A WC of >88 cm for women and >102 cm for men was defined as obese. Data collected included age, gender, American Society of Anaesthesiologists (ASA) score, renal function, anaesthetic duration, surgery duration, blood loss, complications, and duration of hospital stay...

Leiomyosarcoma is a rare and aggressive retroperitoneal tumor arising from the smooth muscle of the tunica media. The IVC accounts for > 70% of all leiomyosarcomas, with the renal vein being limited to few case reports (1)(2)(3)(4)(5). Accurate pre-operative diagnosis is rare as the origin is unclear and its involvement of the vessels makes biopsy prohibitively dangerous (6). Treatment involves radical nephrectomy followed by adjuvant radiation and/or chemotherapy, with poor prognosis (7)(8). Herein, we describe the laproscopic dissection of a retroperitoneal renal vein tumor using a robotic approach...

Erosion of surgical materials into the adjacent organs following surgical procedures is a rare complication. Migrations of these surgical materials into the urinary tract like pelvicalyceal system, ureter and bladder have been reported following various urological procedures. We present a case of migrated Hem-o-Lok clips into the ureter following a laparoscopic partial nephrectomy for angiomyolipoma of the left kidney presented with recurrent urinary tract infection. The case was managed with ureteroscopic removal of clips...

Stereotactic brain biopsies for histopathological diagnosis are a common technique in case of intracranial lesions, particularly in those not amenable for resection. Tumor seeding alongside the surgical trajectory after fine-needle aspiration is a known problem in several visceral tumors. Whereas in these cases a complete resection of the biopsy trajectory may later be performed, this strategy is not feasible in stereotactic brain biopsy. We report a case of tumor seeding along the entire biopsy tract after stereotactic biopsy of a brainstem metastasis...

CLINICAL/METHODICAL ISSUE: In the treatment of localized renal cell carcinoma, the lack of randomization in controlled trials on thermal ablation is a major limitation. The latter leads to significant study bias and it ultimately remains unclear whether the improved overall survival in favor of partial nephrectomy can actually be attributed to the treatment method. STANDARD RADIOLOGICAL METHODS: For T1a (≤4 cm) renal cell carcinoma without lymph node and distant metastases, excellent technical and clinical results have been described after imaging-guided radiofrequency ablation and cryoablation...

INTRODUCTION AND OBJECTIVES: Robotic assisted radical cystectomy (RARC) is an alternative to open radical cystectomy. As experience is gained with the RARC approach the technique is being applied to more complex surgical cases. We describe here our technique for RARC with intracorporeal ileal conduit urinary diversion for a renal transplant recipient. MATERIALS AND METHODS: The patient is a 60-year old man with high-grade muscle invasive bladder cancer. He has a history of renal failure due to polycystic kidney disease and received a deceased donor renal transplant in 2008...

BACKGROUND: Nephron-sparing surgery in the form of partial nephrectomy is increasingly becoming the standard of care in patients with small renal tumours. Oncological outcomes for partial nephrectomy are equivalent to radical nephrectomy, however, clamping of the hilar vessels to allow resection of tumours during partial nephrectomy may cause ischaemic damage to the kidney and result in long-term renal impairment. AIM: We carried out a retrospective review of 43 patients undergoing laparoscopic partial nephrectomy (LPN) and assessed functional and oncological outcomes...

Robotic partial nephrectomy (RPN) is gaining increasing prominence for nephron sparing surgery in the treatment of patients with localized kidney tumors. RPN offers the benefits of minimally invasive surgery with a shorter learning curve compared to its laparoscopic counterpart. While long-term data are awaited, RPN does provide short-term oncological and functional outcomes comparable to open and laparoscopic PN. Further, robotic surgery has facilitated technical innovation including the elimination of warm ischemia, provided minimally invasive alternatives to patients with complex tumors and importantly, has fuelled increased dissemination of PN surgery amongst community urologists...

INTRODUCTION: Variceal hemorrhage from sinistral portal hypertension has never been reported as a complication of live pancreas donation. CASE REPORT: We present a 68-year-old patient who underwent a simultaneous live-donor laparoscopic segmental pancreatectomy and nephrectomy for the purposes of donating to her daughter. Her postoperative course was significant for an episode of acute pancreatitis with a pseudocyst formation. More than a decade later, she presented with variceal hemorrhage from sinistral portal hypertension, which after a diagnostic work-up, prompted a laparoscopic splenectomy...

BACKGROUND: Optimal treatment for established renal failure is living donor kidney transplantation. However this pathway exposes healthy individuals to significant reduction in nephron mass via major surgical procedure. Laparoscopic donor nephrectomy is now the most common method for live donor transplantation, reducing both donor post-operative pain and recovery time. However this procedure exposes kidneys to additional haemodynamic stresses. It has been suggested that donor hydration-particularly the use of preoperative intravenous fluids-may counteract these stresses, reducing subclinical acute kidney injury and ultimately improving long-term renal function...

AIM: To compare laparoscopic and open living donor nephrectomy, based on the results from a single center during a decade. METHODS: This is a retrospective review of all living donor nephrectomies performed at the Massachusetts General Hospital, Harvard Medical School, Boston, between 1/1998 - 12/2009. Overall there were 490 living donors, with 279 undergoing laparoscopic living donor nephrectomy (LLDN) and 211 undergoing open donor nephrectomy (OLDN). Demographic data, operating room time, the effect of the learning curve, the number of conversions from laparoscopic to open surgery, donor preoperative glomerular filtration rate and creatinine (Cr), donor and recipient postoperative Cr, delayed graft function and donor complications were analyzed...

The prognostic role of chromophobe renal cell carcinoma (ChRCC) is still controversial. Here, we report on a patient who lived with tremendous non-progressed renal malignant tumour for eight years. The 32-year-old patient presented to our hospital with a huge renal tumour. Computed tomography (CT) scan showed a tumour 12 cm in diameter at the upper pole of the right kidney. Trans-abdominal laparoscopic right radical nephrectomy was performed. Histopathological examination confirmed this tumour to be a ChRCC...
