Ureteral replacement by non-modelled isoperistaltic ileoplasty.

Objectives: To study the long-term morbidity and efficacy of ureteroileopla sty in a retrospective series of 18 patients. Materials and methods: 12 men and 6 women with a mean age of 50 years under went ureteroileoplasty with unilateral replacement in 15 patients and bilat eral replacement in 3 patients. A total of 21 units renoureteral units were repaired by this technique. The pelvic ureter was replaced in 16 renourete ral units, the lumbar ureter was replaced in I case and the entire ureter w as replaced in 4 cases. The commonest ureteral lesions were strictures seco ndary to ureteroscopy or ureterolithotomy (40%). All patients had normal re nal function, except for one patient with serum creatinine of 224 mu mol/l. Results: With a mean follow-np of 25 months (range: 3 to 64 months) all ure teroileoplasties were patent with no major morbidity. Only the patient with preoperative renal failure developed hyperchloraemic acidosis with deterio ration of her renal function. Conclusion: In the absence of renal failure, ureteroileoplasty is an operat ion with low morbidity achieving goon medium-term results.
