A functional examination of the ureter with electro-ureterography and urometry as well as histological examination of the uretero-pelvic junction was made on 5 cases of congenital hydronephrosis. Among these 5 cases, one case was performed uretero-pelvic anastomosis and another pelvic plastic operation according to Schwyzer-Foley's method, and the rest were performed nephrectomy. The results obtained are as follows: 1) No histological abnormality was found in the uretero-pelvic junction of the affected kidney. 2) Marked reduction in frequency of peristalsis in the ureter of the affected side, compared to that of the normal ureter, was noted, though the direction of the peristalsis was antegrade. 3) In the case which was performed uretro-pelvic anastomosis it was observed that antegrade peristalsis changed into retrograde one after the operation. Then, in order to abolish the retrograde peristalsis, uretrocystostomy was performed. Following this operation, antegrade peristalsis recurred, though its frequency was more reduced than before the first operation, and at the same time, urine volume transferred to the bladder by the ureter of affected side was further reduced. 4) In the case which was performed plastic operation of the ureteropelvic junction, no peristalsis was observed after the operation.
