V03-11 FLEXIBLE URETEROSCOPY-ASSISTED TRANSPERITONEAL ROBOTIC SURGERY FOR THE TREATMENT OF URETERAL STRICTURES: TECHNICAL ASPECTS AND EARLY RESULTS

INTRODUCTION AND OBJECTIVES:Ureteral strictures represent one of the most serious reconstructive challenges for urologists. In this video we present three cases of ureteral strictures, managed with a combination of endoscopic and robot-assisted approach. The first two cases were iatrogenic strictures due to previous ureteral endoscopic surgery performed for stone disease, while the last one was an acquired stricture in a patient with endometriosis, after a gynecological procedureMETHODS:The first two patients had nephrostomy tube before surgery, while the third patient has double J ureteral stent to avoid obstructive urophaty. The preoperative work-up was performed with a computed tomography scan, renal scintigraphy and diagnostic ureteroscopy with retrograde pyelography to confirm the position and the length of the stricture. In these cases a combined endoscopic and robot-assisted approach was used. The patients were positioned in the standard flank position. Four robotic trocars were placed in line alon...
