The repair of long-segment ureteral defects poses a challenge for urologists. Surgical techniques such as ureteroureterostomy, a psoas hitch, a Boari flap, or autotransplantation can be used as alternative treatment techniques depending on the length and location of the ureteral injury. Due to the difficulties and limitations of all these techniques, ileal substitution methods may be required in some cases. The Yang-Monti procedure, a well-known ileal substitution technique, allocates a retubularized ileal segment after detubularization at the antimesenteric axis to create an isoperistaltic conduit. This case series features the Yang-Monti procedure for various acquired and iatrogenic ureteral defects.
