ABSTRACT
PURPOSE:
Ureteral necrosis is a serious problem in kidney transplantation. Sometimes re-ureterocystostomy is possible, while other cases require an elaborate reconstruction to maintain kidney function. We report our experience with ileum interposition for ureteral reconstruction.METHODS:
After 9 years of dialysis treatment a 58-year-old patient was grafted using the left kidney of a 59-year-old donor with a cold ischemic time of 9.5 hours. The early postoperative course was uneventful apart from delayed graft function. Immunosuppression consisted of an IL-2-receptor antibody, calcineurin inhibitor, mycophenolate mofetil, and corticosteroids. Discharge serum creatinine was 2.3 mg/dL. In month 4 the patient showed a pararenal urinoma; cystoscopy revealed necrosis of the distal ureter. Operative revision showed urine leakage from the renal pelvis through the urinoma into the bladder. As the whole ureter was necrotic, a re-ureterocystostomy was not possible. The patient's own ureter had been extirpated, and the bladder was too small to do a direct anastomosis between it and the kidney. Consequently, an ileum interposition was performed.RESULTS:
The postoperative course was uneventful. Kidney function was stable with a nadir creatinine concentration of 2.0 mg/dL 18 months' posttransplantation, and 14 months' post ileal interposition the kidney function was still satisfactory, with a creatinine level of 2.0 mg/dL.CONCLUSION:
Ureteral necrosis is a serious complication following kidney transplantation. Whenever a re-ureterocystostomy or an uretero-ureterostomy is not possible, the interposition of the ileal segment represented a safe procedure to deal with this problem.
