Two girls (4 and 3-year old) visited our out-patient service complaining of daytime and nighttime enuresis. Both were diagnosed as ectopic ureteral opening to the vagina with a concomitant dysplastic kidney on the left side. These anomalies were repaired by ureterocystoneostomy according to a modified Gregoir's method. In the first case, three months later, DIP visualized left upper urinary tract which had not been seen before, but enhanced CT scan, renogram and scintigraphy with Tc-DMSA showed no change. In the second case, three years later, examination results were the same as in the first case. There was no renal development. Surgical repair of ureterocystoneostomy was valuable, with small surgical damage and cosmetic merit for the girls. Furthermore, renal function will be maintained at the same level or slightly higher than that before the operation.
