Ipsilateral ureteroureterostomy for single ureteral disease in patients with ureteral duplication: a review of 8 years of experience with 16 patients.

Ipsilateral ureteroureterostomy near the bladder (end-to-side anastomosis) for treatment of single ureteral disease in patients with complete ureteral duplication has been performed in 16 patients during the last 8 years. The operative technique, indications, results, followup and complications are presented. Reflux in the lower segment ureter was treated in 13 patients and upper segment ectopia or ureterocele was managed in 3 patients with this operative procedure. This operative technique is simpler and safer than reimplantation of both ureters into the bladder. Because no dissection of the bladder wall is needed there is less risk of injury to the pelvic viscera and vasculature. The chance of success in correcting reflux appears better than with reimplantation of both ureters into the bladder. Long-term followup has shown few complications and no repeat operations were needed in this series. The small stump of the diseased ureter left behind near the bladder caused no serious problems.
