[Ureteral replacement with appendix].
OBJECTIVE: The scant references in the literature on the use of the appendix in ureteral substitution prompted us to describe the present case in whom this technique was utilized. METHODS: The surgical technique of appendiceal interposition to repair a defect approximately 10 cm long in the right ureter is described. Following excision of a mass arising from the adnexa that entrapped the ureter at the level of the pelvis, the defect was repaired with the appendix. RESULTS: At two years follow-up, the patient is well and right excretory system function is normal. CONCLUSION: Ureteral repair with the appendix is simple and easy to perform. However, the indications for appendiceal interposition are more limited than those of the classical surgical techniques.
