postoperatively and at least annually thereafter. RESULTS: The follow up period was from 3 months up to 18 years (mean 8.5 0.8 years). Postoperative complications developed in 16 (9.4%) cases. Short-term complications (less than 30 days postoperatively) occurred in 12 (7.1%) patients and included: intestinal obstruction -4 (2.4%), ileal graft mesentery thrombosis -2 (1.2%), bleeding -2 (1.2%), and acute pyelonephritis e 4 (2.4%). Late complication e stricture of uretero-ileal anastomosis developed in 4 patients (2.4%) in 3 months after operation. Thus, the complications which have required surgical treatment occurred at 12 (7.1%) patients. The results of all operations were successful. According to all patients the renal function was restored. There were no cases of metabolic acidosis. CONCLUSIONS: Ileal and appendicular ureteral reconstruction is a safe and efficacious procedures in patients with extended and multiple ureteral strictures. During long-term follow-up major complications are rare and renal function remains good.
