Ureteropyelostomy: a simple and effective treatment for symptomatic ureteroureteric reflux.

Partial ureteric duplication may cause delayed drainage of urine from the upper tracts because of ureteroureteric "see-saw" reflux. This can be eliminated by the procedure of ureteropyelostomy, in which the partially duplicated ureter is converted into a bifid renal pelvis. This operation leaves a short anastomotic suture line and has a low complication rate. We report seven patients who have undergone ureteropyelostomy for symptomatic ureteroureteric reflux. All remain symptom-free after follow-up for a minimum of 1 year.
