Combined laparoendoscopic single-site ureterolithotomy and flexible cystoscopy in the treatment of concurrent large upper ureteral and renal stones

AbstractObjective: The aim of this study was to present the authors’ experience with technical recommendations for the treatment of concurrent large upper ureteral and renal stones.Methods: Between September 2014 and March 2016, laparoendoscopic single-site surgery (LESS) ureterolithotomy with renal stone extraction or holmium laser lithotripsy under flexible cystoscopy was performed on 15 patients who had concurrent upper ureteral and renal stones. The ureteral stone was treated with LESS ureterolithotomy. After the ureteral stone had been removed, a flexible cystoscope was inserted through one of the laparoscopic ports into the renal pelvis and collecting systems. Renal stones were extracted with a stone basket or broken by a holmium laser and then removed. The perioperative and postoperative data were collected and analyzed retrospectively. Patients were followed up postoperatively for evidence of long-term side-effects.Results: Nine patients underwent LESS ureterolithotomy and flexible cystoscope-assi...
