Abstract

Objective: To describe the technical aspects of robot assisted laparoscopic ureteral reimplantation (RALUR) for the management of primary obstructive megaureter (POM) and report initial outcomes, safety, and feasibility of the procedure. Methods: Using an IRB- approved robotic surgery registry, we performed a retrospective chart review of patients undergoing RALUR for POM between April 2009 and May 2019. Results: A total of 18 patients underwent RALUR using a modified Lich-Gregoir technique for management of POM and 7 (38.9%) of these underwent intracorporeal ureteral tapering at the time of surgery. At median follow up of 27.5 (IQR 11-50) months, no patient required reoperation for recurrent obstruction and all patients had improvement in hydronephrosis postoperatively. 30-day complications were low with 1 Grade I, 2 Grade II and 1 Grade III Clavien-Dindo complication. The most common issue postoperatively was febrile urinary tract infection, occurring in 6 patients (33.3%), at an average of 3.2 months after surgery. Increased operative time was the only significant difference between the tapered verses nontapered group. Conclusion: We present the largest series of RALUR for POM to date. Based upon our initial experience with this technique we believe it is technically feasible and reproducible with good outcomes and low complication rates. Future studies are needed to track long-term outcomes and better understand indications for and the utility of ureteral tapering as well as how to minimize febrile UTIs postoperatively. Additional follow up is needed to determine the efficacy of RALUR as compared to open ureteral reimplantation for POM.
