摘　　要：Objective:Secondary pyeloplasty for recurrent ureteropelvic junction obstructions may be a safe and feasible surgical option for patients.This study aimed to demonstrate outcomes of utilizing a non-transecting buccal mucosa graft ureteroplasty for management of recurrent ureteropelvic junction obstruction after prior failed pyeloplasty.Methods:We performed a retrospective review of our Collaborative of Reconstructive Robotic Ureteral Surgery database for all consecutive patients who underwent buccal mucosa graft ureteroplasty between April 2012 and June 2022 for management of recurrent ureteropelvic junction obstructions after prior failed pyeloplasty.The primary outcome included surgical success which was defined as the absence of flank pain and no obstruction on imaging.Results:Overall,ten patients were included in our analysis.The median stricture length was 2.5(interquartile range[IQR]1.8-4.0)cm.The median operative time was 230.5(IQR 199.5-287.0)min and median estimated blood loss was 50.0(IQR 28.8-102.5)mL.At a median follow-up of 10.3(IQR 6.2-14.8)months,80%of patients were surgically successful and there were no major(ClavieneDindo Grade>2)complications.Conclusion:Buccal mucosa graft ureteroplasty is a valuable non-transecting surgical option for patients with recurrent ureteropelvic junction obstructions who failed prior pyeloplasty and has comparable outcomes to the literature regarding standard transecting techniques.
