OBJECTIVES: To compare outcomes and survival of open, robotic, and laparoscopic nephroureterectomy (ONU, RNU, LNU) using population-based data. METHODS: Using the National Cancer Database, we identified patients who underwent nephroureterectomy for localized UTUC between 2010 and 2013. Demographic and clinicopathologic characteristics were compared among the three operative approaches. Multivariate regression analyses were used to determine the impact of approach on performance of lymphadenectomy (LND), positive surgical margins (PSM), and overall survival (OS)...

Upper tract urothelial carcinoma is a relatively uncommon malignancy. The gold standard treatment for this type of neoplasm is an open radical nephroureterectomy with excision of the bladder cuff. This systematic review compares the perioperative and oncologic outcomes for the open surgical method with the alternative surgical management options of laparoscopic nephroureterectomy and robot-assisted nephroureterectomy (RANU). MEDLINE, EMBASE, PubMed, and Cochrane Library databases were searched using a sensitive search strategy...

Introduction When performing open or laparoscopic nephroureterectomy (LNU), the optimal way to excise the distal ureter remains controversial. There are concerns that primary endoscopic detachment of the intramural ureter is associated with adverse outcomes. Existing studies have limited patient numbers and inadequate oncologic follow up. We provide our institutions experience of this technique. Methods Data was collected prospectively on 59 patients (37 men) who underwent LNU over a 10 year period at a single centre using a standardized technique; initial endoscopic circumferential release of the distal ureter and bladder cuff followed by retroperitoneal en bloc LNU...

INTRODUCTION: To evaluate temporal trends in the delivery and extent of lymphadenectomy (LND) in radical nephroureterectomy (RNU) performed in upper tract urothelial carcinoma (UTUC) patients. METHODS: We evaluated a multi institutional collaborative database composed by 1512 consecutive patients diagnosed with UTUC treated with RNU between 1990 and 2016. Year of surgery were grouped in five periods: 1990-1996, 1997-2002, 2003-2007, 2008-2012 and 2013-2016. Data about LND were available for all patients and numbers of nodes removed and positive were reported by dedicate uropathologists...

A 68-year-old man underwent an inguinal orchiectomy for a right testicular tumor and the pathological diagnosis was atypical lipomatous tumor. Nine years later, a resection procedure was performed for local recurrence. Five years after that second surgery, abdominal computed tomography (CT) findings revealed a low density mass 40 mm in size on the back side of the right kidney and enlarged fat in the retroperitoneal space. We performed a laparoscopic tumor resection under a diagnosis of lipoma or liposarcoma recurrence, and the pathological diagnosis was well differentiated liposarcoma...

BACKGROUND: Many studies have reported the oncological outcomes between open radical nephroureterectomy (ONU) and laparoscopic radical nephroureterectomy (LNU) of upper tract urothelial carcinoma (UTUC). However, few data have focused on the oncological outcomes of LNU in the subgroup of localized and/or locally advanced UTUC (T1-4/N0-X). The purpose of this study was to compare the oncological outcomes of LNU vs. ONU for the treatment in patients with T1-4/N0-X UTUC. METHODS: We collected and analyzed the data and clinical outcomes retrospectively for 265 patients who underwent radical nephroureterectomy for T1-4/N0-X UTUC between April 2000 and April 2013 at two Chinese tertiary hospitals...

AIM: To evaluate the success of endoscopic deroofing with double J (DJ) stenting as a primary treatment modality of uncomplicated ureterocele. PATIENTS AND METHODS: All babies with uncomplicated ureterocele referred to us between 2005 and 2015 were to be prospectively recruited into the study without any exception. The preoperative management would include ultrasound KUB on a fixed protocol, micturating cystourethrogram, DTPA scan and MRU (magnetic resonance urography) or IVP (intravenous pyelography)...

OBJECTIVE: To report a contemporary series of surgically treated patients with tumors involving kidneys with fusion anomalies. MATERIALS AND METHODS: We retrospectively reviewed the medical records of all 10 patients treated at a single tertiary care institution for tumors involving kidneys with fusion anomalies between the years 2000 and 2015. One patient, diagnosed with lymphoma, did not undergo surgical treatment and was therefore excluded. Data regarding patient, tumor, and treatment characteristics were collected and described...

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...

OBJECTIVES: To examine the effect of surgical approach on regional lymphadenectomy (LND) performance and inpatient complications for radical nephroureterectomy (NU) using a national administrative database. METHODS: The National Inpatient Sample (2009-2012) was used to identify patients who underwent NU for urothelial carcinoma. Cohorts were stratified by performance of LND. Covariates included patient demographics, comorbidity, hospital characteristics, hospital volume, performance of LND, surgical approach (open [ONU], laparoscopic [LNU], or robotic [RNU]), and complications...

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...
