[Treatment of ureteral stenosis with vermiform appendix]

Contribution of one case of iatrogenic ureteral stenosis, successfully managed in a single-kidney patient by substitution with a vermiform appendage. Description of the technique used and brief review of open surgery techniques used in repair of ureteral defects. After a two-year follow-up, the correct functioning of the appendicular graft with preserved renal morphological function is confirmed. Ureteral substitution with an appendage is a good indication for extensive ureteral defects with right mid-ureter location.
