Kidney Transplantation After Multiple Urinary Tract Conversion with an Ileal Conduit: A Case Report

Kidney transplantation (KTx) after urinary tract conversion surgery is extremely difficult due to several complications. In our case, KTx was performed after multiple operative procedures, including diversion urethrostomy.

The patient was a 46-year-old woman with a right atrophic kidney, an ectopic opening of the left ureter, and urethral dysplasia since birth. The patient underwent a right nephrectomy, left ureteral sigmoidostomy, Stamey surgery, augmentation ileocystoplasty, and left ureteroileostomy. Thereafter, she underwent nephrostomy, ileal conduit diversion, open sigmoid colectomy, and total cystectomy because of persistent urinary incontinence, sigmoid colon cancer, and recurrent cystitis. Her renal function gradually deteriorated, and hemodialysis was initiated. Before the KTx, she underwent laparoscopic left nephrectomy, an intraperitoneal adhesion debridement, and left ileal conduit resection. We dissected the left ileal conduit in the abdominal cavity and penetrated the anorectal side of the free ileal conduit into the wall of the right side of the abdomen. Thereafter, a kidney from a living donor was transplanted into the right iliac fossa through the existing right ileal conduit when the patient was 46 years old. The allograft function was stable without rejection for 2 years.

We report the case of a patient who underwent multiple urethral modifications followed by ileal conduit transfer and living donor KTx, which progressed without major postoperative complications.
