title: Clinical experience of the Kock continent ileal urinary reservoir in 20 cases focusing on complications.
abstract: From August 1986 through July 1990, 20 patients underwent construction of the Kock continent ileal reservoir and were observed for more than three months. The early complications within the first 3 months were wound infection in four patients (20%), leakage at uretero-intestinal anastomosis in three patients (15%), prolapse of efferent limb and ileus in two patients (10%) and reflux, ureteral stenosis, intestinal fistula and postoperative pancreatitis in one patient (5%). The three late complications included stone formation in two patients and stenosis at an afferent limb in one patient. The stenosis occurred at the position of Dacron collar. The patients were divided into two groups and we compared the recent 10 patients with the initial 10 patients on complications and end results. In the initial group, 8 patients (80%) had 14 complications. In the recent group, 4 patients had 4 complications. The early complications have been reduced with the increase of Kock pouch operation. The result of the recent group was better than that of the initial group. Frequency of postoperative hydronephrosis in patients with Kock pouch was investigated. In nine patients (45%) the minimal hydronephrosis occurred within the first two months and in 5 patients (25%) three months after the operation. It had a normalizing tendency. The maximum pouch pressure at the pouch volume of 400 to 500 ml was not significantly high (37.9 +/- 12.2 cmH2O, mean +/- S.D.).
