Materials And Methods: The study included 75 patients with high anesthesia-related risks for conventional surgery (TURP). All patients were surveyed for symptom burden, using IPSS and quality of life score.
Objective: To assess the safety and efficacy of emergency ureteroscopy (URS) compared with elective URS.
Methods: We conducted a retrospective analysis of patients who underwent URS for isolated ureteral stones in a single center from October 2001 to February 2014. Our patient cohort was divided into two groups: an emergency URS group (Group A), which consisted of patients who underwent URS within the first 24 h of admission, and an elective or planned URS group (Group B).
Robotic radical nephroureterectomy (RRNU) may offer advantages over laparoscopic radical nephroureterectomy (LRNU). The purpose of this study is to evaluate the overall survival (OS) of patients with upper tract urothelial carcinoma (UTUC) who underwent RRNU LRNU and identify factors that account for differences. The National Cancer Database was queried from 2010 to 2016 for patients with American Joint Committee on Cancer 6th/7th edition Stage I/II/III UTUC.

Introduction: Laparoscopic preparation of the ureter is a challenging part of upper urinary tract reconstruction, due to limited depth perception provided by the camera and lack of wristed motion of most laparoscopic instruments needed for adequate spatulation and scar tissue removal. One solution has been to perform the more difficult portions of the surgery in an extracorporeal manner. A hybrid intracorporeal-extracorporeal approach to upper tract ureteral reconstruction facilitates ureteral preparation at the stage of mastering the technique.
