A 44-year-old male patient visited our hospital with a chief complaint of macroscopic hematuria. Prostate biopsies were performed due to prostate specific antigen (PSA) 11.6 ng/ml, and he was diagnosed with Gleason score 5+4 prostate cancer. Computed tomography showed a left hypoplastic kidney. T2- weighted magnetic resonance imaging showed the left ureter stump with ectopic insertion into the dilated left seminal vesicle. He was diagnosed with high-risk prostate cancer and left ectopic ureter inserting into the seminal vesicle with ipsilateral hypoplastic kidney...

Background. Several factors have been validated as predictors of disease recurrence in upper tract urothelial carcinoma. However, the oncological outcomes between different surgical approaches (open nephroureterectomy versus laparoscopic nephroureterectomy, ONU vs LNU) remain controversial. Therefore, we performed a meta-analysis to evaluate the oncological outcomes associated with different surgical approaches. Methods. We conducted an electronic search of the PubMed, Embase, ISI Web of Knowledge and Cochrane Library electronic databases through November 2015, screened the retrieved references, collected and evaluated the relevant information...

BACKGROUND AND PURPOSE: To describe a novel and pure laparoscopic approach using a custom-made bulldog clamp with modified port placement for management of distal ureter during laparoscopic nephroureterectomy. PATIENTS AND METHODS: Between October 2013 and December 2014, 31 patients found to have upper tract urothelial carcinoma were treated using this technique. After finishing a standard laparoscopic transperitoneal nephrectomy in a 45° to 60° recumbent position, an additional 12-mm trocar was inserted at the lower abdomen to allow the surgeon to continue dissecting the ureter caudally toward the bladder wall without repositioning the patient...

Since the first description of the laparoendoscopic single-site surgery (LESS) in the pediatric urology population, various authors have shared their experiences and results. We aim to provide a review of current studies of LESS and share our experience with this modality. The current literature describes the use of LESS for most surgeries performed in the pediatric urology population with similar results to open and standard laparoscopic surgery. The authors have described their experiences with transabdominal and retroperitoneal nephrectomy, nephroureterectomy, pyeloplasty, orchidopexy, varicocelectomy, and renal cyst decortication...

Controversies exist about the best method for managing the distal ureter during the laparoscopic (LNU) and robot-assisted nephroureterectomy (RANU). Therefore, PubMed, Scopus and Web of Science databases were searched in order to identify articles describing the management of distal ureter during LNU or RANU in patients suffering from upper urinary tract urothelial cell carcinoma. Forty seven articles were selected for their relevance to the subject of this review. The approaches that are usually performed regarding the distal ureter management are open excision, transurethral resection of ureteral orifice (Pluck Technique), ureteric intussusception and pure LNU or pure RANU...

BACKGROUND AND PURPOSE: Prolonged operative time (ORT) is often considered a drawback to minimally invasive surgery (MIS) because of increased morbidity. Limited data exist comparing long laparoscopic ORT with similar or shorter open ORT. This study aims to identify ORT when a minimally invasive procedure becomes inferior to its open counterpart. METHODS: Minimally invasive and open total and partial nephrectomies and nephroureterectomies were identified in the National Surgical Quality Improvement Program (NSQIP) from 2005 to 2012...

INTRODUCTON: Radical nephroureterectomy for upper tract urothelial carcinoma (UTUC) must include some form of distal ureter management to avoid high rates of tumour recurrence. It is uncertain which distal ureter management technique has the best oncologic outcomes. To determine which distal ureter management technique resulted in the lowest tumour recurrence rate, we analyzed a multi-institutional Canadian radical nephroureterectomy database. METHODS: We retrospectively analyzed patients who underwent radical nephroureterectomy with distal ureter management for UTUC between January 1990 and June 2010 at 10 Canadian tertiary hospitals...

Robot-assisted laparoscopic surgery is increasingly used in urologic oncologic surgery. Robotic nephroureterectomy is still a relatively new technique. As upper tract urothelial carcinoma is a rare disease, intermediate- and long-term outcome data are scarce. However, robotic nephroureterectomy does seem to offer advantages to open and laparoscopic counterparts, with comparable short-term oncologic and functional outcomes. Here the authors review the robotic surgical management of upper tract urothelial carcinoma, with a review of the steps and tips on making this approach more widely adoptable...
