title: Kidney transplantation into urinary conduits with ureteroureterostomy between transplant and native ureter: single-center experience.
abstract: OBJECTIVE
  To evaluate the functional outcomes and complications after allogeneic kidney transplantation into recipients with a urinary conduit using ureteroureterostomy between the transplant and native ureter.
  
  
  METHODS
  We performed a retrospective study of 6 patients with a pre-existing urinary conduit undergoing kidney transplantation at a single tertiary academic center from May 1982 to February 2007.
  
  
  RESULTS
  The study included 1 female and 5 males aged 16 to 65 years. Two patients received a living donor transplant. The indications for pretransplant conduit formation were neurogenic bladder in 3 and bladder contraction with vesicoureteral reflux in 3. One patient received a colon conduit. All patients underwent kidney transplantation into a urinary conduit using ureteroureterostomy between the transplant ureter and the ipsilateral native ureter. The average interval between conduit formation and kidney transplantation was 83.5 months and the average time of requiring hemodialysis was 56.3 months. The mean follow-up was 5.3 years. The patient and graft survival rate was 100% and 83.3%, respectively. The 3-year serum creatinine averaged 1.4 mg/dL. One graft was lost because of chronic rejection. Transplant ureter obstruction occurred in 2 patients and required endoscopy or open revision. Four patients underwent post-transplant native nephrectomy for recurrent pyelonephritis. Three patients were hospitalized for treatment of graft pyelonephritis.
  
  
  CONCLUSIONS
  In our experience, ureteroureterostomy between the transplant and native ureter is technically feasible and provides good functional results despite a high incidence of urinary tract infection. We recommend this approach in renal transplant recipients with a short contracted conduit or in those in whom the donor ureter is too short to warrant a tension-free ureteroileal anastomosis.
