[Kidney transplantation in patients with anomalies of the lower urinary tract]

In the transplant centre in Erlangen-Nuremberg, 1242 patients underwent renal transplantation between 1966 and 1993. In 4.5% of cases (56 patients) the renal end stage disease had been caused by severe abnormalities or functional disturbance of the lower urinary tract. Despite long-standing defunctionalization, urinary diversions and multiple operative procedures, it was possible to use the original bladder for ureterocystoneostomy in all patients. Only 1 patient needed an enterocystoplasty after transplantation. Altogether 72 transplantations have been performed in 56 patients ranging from 10.2 to 62.7 years of age. At follow up, 40 patients (71%) had a functioning graft with a mean serum creatinine level of 1.5 mg%. The 5-year transplant survival rate is 57.3%. Our results suggest that carefully planned renal transplantation in urological patients has results comparable to those obtained in other, non-risk, kidney transplant recipients. The methods of bladder reconstruction and augmentation, intermittent self-catheterization as well as anticholinergics and continuous antibiotic prophylaxis combine to make the ileal or colonic conduits needed earlier unnecessary.
