PURPOSE: To determine if segmental ureterectomy (SU) could be chosen for wider oncological indications than low-risk ureteral carcinoma, given the difficulties in accurate preoperative risk stratification determination and kidney-sparing needs for successive therapy. METHODS: Data from ureteral carcinoma patients who underwent open SU or laparoscopic radical nephroureterectomy (RNU) between 2011 and 2016 were retrospectively reviewed. Kaplan-Meier survival analysis and Cox regression model with patients' baseline characteristics (age, bladder cancer history, hydronephrosis), procedure type, and tumor characteristics (site, size, pathological features) as covariates were used to evaluate oncological outcomes...

Purpose: We compared oncologic outcomes of patients with upper tract urothelial carcinoma (UTUC) who underwent open nephroureterectomy (ONU) or laparoscopic nephroureterectomy (LNU). Materials and Methods: Consecutive cases of ONU and LNU between 2000 and 2012 at five participating institutions were included in this retrospective analysis. Clinical characteristics and pathologic outcomes were compared between the two surgical approaches. The influence of the type of surgical approach on intravesical recurrence-free survival (IVRFS), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) was analyzed using the Kaplan-Meier method and differences were assessed with the log-rank test...

PURPOSE: There is a lack of reporting of the bladder cuff pathology in the literature and ongoing debate regarding the role of bladder cuff excision (BCE) in the prognosis in patients with upper tract urothelial carcinoma (UTUC). We aimed to know the risk factors, the survival, and the clinical course of such pathology. MATERIALS AND METHODS: The study was retrospective, from 1983-2013 on 305 patients who had diagnosed with UTUC. Patients were managed by radical open/ laparoscopic nephroureterectomy with bladder cuff excision...

Upper tract urothelial carcinoma is a rare malignancy that has an abundance of surgical treatment options, including open, laparoscopic, robotic, and endoscopic approaches. As advances in technology allow for shorter, less morbid operations, the variation in care of this uncommon disease has raised concerns about compromising oncologic principles. Many institutions have described their experience with promising results; however, there is a paucity of high-quality data that supports the use of robotic surgery as a new gold standard...

Robot assistance has been rapidly adopted by urological surgeons and has become particularly popular for oncological procedures involving the retroperitoneal space. The wide dissemination of robot assistance probably reflects the limited amount of operating space available within the retroperitoneum and the advantages provided by robot-assisted approaches, including 3D imaging, wristed instrumentation and the shorter learning curve compared with that associated with the equivalent laparoscopic techniques. Surgical procedures that have traditionally been performed using an open or laparoscopic approach, such as partial nephrectomy, radical nephrectomy, retroperitoneal lymph node dissection, nephroureterectomy and adrenalectomy, are now often being performed using robot assistance...

PURPOSE: Since conditional survival analysis provides better estimates of survival time at each followup, we assessed changes in conditional intravesical recurrence-free survival rates after radical nephroureterectomy. We also sought to determine how the impact of well-known risk factors evolves with time, particularly in patients with localized upper tract urothelial carcinoma. MATERIALS AND METHODS: We identified 364 patients with Ta-3N0M0 localized upper tract urothelial carcinoma who underwent open or laparoscopic radical nephroureterectomy at 1 of our 3 institutions...

OBJECTIVE: For locally advanced cervical carcinoma, concurrent chemoradiotherapy (CCRT) is the standard treatment, however, CCRT can lead to development of a vesicovaginal or rectovaginal fistula [1]. Treatment options are limited for patients with laterally recurrent cervical carcinoma and fistula formation after CCRT. Chemotherapy with bevacizumab is now used for recurrent or advanced cervical carcinoma, but this treatment is associated with fistula formation [2]. When the recurrent mass is confined to the pelvic cavity, complete surgical resection with negative margins offers the most promise; however, the resectability rate is low in cases of laterally recurrent tumor [3], which may include bony structures, and survival outcomes seem to be poor in cases of a laterally recurrent vs...

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 number of patients and inadequate oncologic follow-up. We provide our institutions experience of this technique. MATERIALS AND METHODS: Data were collected prospectively on 59 patients (37 men) who underwent LNU for a 10-year period at a single center using a standardized technique: initial endoscopic circumferential release of the distal ureter and bladder cuff followed by retroperitoneal en bloc LNU...
