Abstract

Duplication of renal pelvis and ureter is the most common congenital anomaly of that upper urinary tact. The three most important abnormalities associated with duplex kidneys are V-U reflux, ectopic ureter and ureterocele. There is no single method of treating V-U reflux with complete ureteric duplication which will apply to all cases. With reflux, the pole segment of duplicated kidney may be severly diseased and must be removed by partial nephroureterectomy. Another surgical approach to the problem of reflux in duplicated ureters is "common sheath" reimplantation generally. But there are high risk of injuries to pelvic viscera and vasculatures. We performed ipsilateral ureteroureterostomy (end-to-side anastomosis) using microsurgery for another alternative method. We found there are no risk of injuries to the pelvic viscera anti vasculatures, the procedure is very simple and the result is very excellent. Herein we report our cases with brief review of literatures.
