OBJECTIVE: We studied the long-term renal graft functions, survivals, and complications among patients with augmented bladders. PATIENTS AND METHODS: Between 1976 and 2008, we performed 6/2600 renal transplantations in patients with augmented bladders. The mean patient age was 52 years. The cause of end-stage renal disease was chronic interstitial kidney disease in all patients, being secondary to lower urinary tract dysfunction. The etiology of bladder dysfunction was tuberculosis in 4 cases, bladder exstrophy in 1, and myelomeningocele in 1. Enterocystoplasty had been performed at a mean of 19 years prior to transplantation. The ureter was implanted into the native ureter in 5 cases and the bowel segment in 1 case. RESULTS: With a mean follow-up of 56 months (range, 20-100 months), the overall graft survival was 50%. Three grafts were lost due to venous thrombosis (n = 1), and chronic allograft nephropathy (n = 2) at 37 and 100 months posttransplantation. No patient died during follow-up. Mean serum creatinine was 1.44 mg/dL with Modification of Diet in Renal Disease (MDRD) clearance of 76 mL/min/1.73 m(2). One fistula that caused obstructive uropathy and 2 cases of migration of a double J catheter were among the surgical complications. These patients showed a mean of 7 episodes of uncomplicated urinary infections. Only 1 patient was rehospitalized due to a complicated urinary tract infection. CONCLUSIONS: Patients with enterocystoplasty and renal transplantation show a greater risk of urinary tract infections, albeit mostly uncomplicated. Despite this, the long-term results are acceptable.
