[Urologic complications in renal transplantation. Our experience with 700 cases]

The present study reports on the urological complications observed in 700 kidney transplants performed from February, 1975 to January, 1993. The techniques used for reconstruction of the urinary tract have been extravesical and intravesical ureteroneocystostomy. In some cases other different techniques have been used. Urinary extravasation, ureteric obstruction and lymphoceles were the most frequent complications. Urinary leakage was observed in 5.7% and was resolved by different surgical techniques, but generally by open surgery. Ureteric obstruction has been a very uncommon complication resolved by conservative treatment or open surgery. Twenty-six lymphoceles were diagnosed. We advocate the use of both open surgery and percutaneous techniques for the management of urological complications secondary to renal transplantation.
