5 Cases of Dismembered Spatulated Ureteropyeloplasty in Marked Hydronephrosis

Park, Yong Hyun

Abstract

The effect of dismembered spatulated ureteropyeloplasty on irreparable severe hydronephrosis in 5 cases during the period from November 1970 to May 1972 was investigated. 5 cases which were performed ureteropyeloplasty were observed for 1 to 5 months. The results were summarized as follows: 1. Hydronephrosis particularly pyelectasis secondary to obstruction or stricture at the ureteropelvic junction was caused by aberrant vessel in 3 kidneys, fibrous band in 2 kidneys and congenital stricture in 1 kidney. 2. 2 aberrant vessels of 3 cases were cut and the other was not because of ischemia of corresponding lower pole. 3. 2 cases with nephrostomy showed no complication of urinary leakage. 4. Follow up study in 1 case of 2 cases with nephrostomy was performed, which improved renal function, hydronephrosis and disappeared infection signs. 5. 4 kidneys without nephrostomy and splinting showed improved renal function and disappeared infection signs, but improvement of hydronephrosis was not obtained.
