The present study evaluates extravesical ureteroneocystostomy, the technique used for reconstruction of the urinary tract in 120 kidney transplants. The urological complications ascribable to this technique were observed in 10% (12/120) and consisted of urinary extravasation (10), and ureteric obstruction (2). The treatment of the foregoing complications, which was successful in 8 cases, is described. The indications and advantages afforded by this technique in renal transplantation are discussed.
