Retroperitoneal robotic-assisted laparoscopic reimplantation of a ureter into an ileal conduit.

A novel technique for managing ureteroenteric strictures is robotic-assisted retroperitoneal laparoscopic reimplantation. A 63-year-old morbidly obese male underwent a left nephroureterectomy and cystoprostatectomy after neoadjuvant chemotherapy for transitional cell carcinoma of both the bladder and left kidney. His single right ureter was anastomosed to the ileal conduit. Postoperatively, he developed acute renal failure and hydronephrosis. An antegrade pyelogram demonstrated a distal stricture that failed two attempts at endoscopic management. In an effort to avoid the morbidity of an open repair, we present a minimally invasive option that replicates the steps of an open reimplantation.
