Abstract
We describe a method of robotic ureterocalicostomy (RALUC) with the Da Vinci Single Port (SP) platform and present clinical outcomes in our cohort of patients. We retrospectively reviewed all patients undergoing RALUC with the SP platform in a single-institution, IRB-approved database between 2020-2023. Demographics, preoperative, intraoperative, and postoperative outcomes were collated. Surgical success was defined as freedom from hardware, avoidance of additional surgical reconstruction, and no obstruction on follow up imaging/ureteroscopy. An incision is made 1/3rd the distance from anterior superior iliac spine to the umbilicus. The retroperitoneal space is entered and SP Access Port is placed. The psoas is identified and concomitant ureteroscopy is used to identify the ureter. The ureter is dissected to the most proximal aspect and transected. The remaining proximal ureteral stump is suture ligated. The lower pole parenchyma is removed to access the calyx. Absorbable barbed suture is used to control parenchymal bleeding and evert the mucosal edge of the calyx. Barbed suture is then used for the ureterocaliceal anastomosis over a ureteral stent. Six patients underwent RALUC. Retroperitoneal approach was used for 5/6 cases. Prior ureteral surgery had been performed in 4/6 patients. Fifty percent of cases included an additional procedure with a median operative time of 248 minutes. One patient required nephrostomy tube placement postoperatively. Median follow up was 10.35 months with surgical success rate of 67%. SP RALUC is a safe and feasible option for proximal ureteral reconstruction in patients with unfavorable upper urinary tract anatomy or in salvage cases.
