Abstract
A total of 111 adults underwent repair of congenital ureteropelvic junction obstruction during a 15-year period. A majority of the patients (77 per cent) presented with flank pain. In all patients established (89 per cent) or intermittent (11 per cent) hydronephrosis was demonstrated. In contrast with our former practice, a majority of the patients (86 percent) underwent dismembered pyeloplasty with intubation. Of the 10 hypertensive patients 8 remained hypertensive postoperatively but only 3 of 22 patients with stones had recurrent calculi. The success rate was 95 per cent with 1 operation. Three patients required a second repair and 1 underwent nephrectomy. Therefore, the eventual success rate was 99 per cent.
