Partial excisional tapering: Report of initial four cases of a novel modification of ureteroplasty for megaureter

Abstract

Introduction We report our initial experience with a novel ureteroplasty technique that combines the advantages of excisional tapering and folding. Methods and cases Following dissection of the megaureter, the distal ureteral end was transected at a point with an appropriate caliber to create a neo‐orifice, which was left intact. Only the proximally redundant part of the ureter was excised and closed over a 10F catheter, following which the ureter was anastomosed to the bladder with an indwelling ureteral stent. This procedure was performed in four pediatric patients. Case 1 involved a 6‐year‐old girl with continuous urinary incontinence due to ureteral ectopia in a duplex system. Cases 2 and 3 involved infants with refluxing megaureter. Case 4 involved a 9‐year‐old boy with a ureteral stone impacted in a megaureter. All four patients achieved successful outcomes without ureteral obstruction. Conclusion This ureteroplasty technique is a promising alternative in specific patients.
