[Urologic complications after 333 kidney transplantations].

26 urological complications were observed in 25 patients following 333 kidney transplantations. The low incidence of these complications (7.8%) is largely due to the systematic resort to the Leadbetter-Politano ureterovesical anastomosis, except in one case (uretero-ureterostomy due to the shortness of the graft). We recorded 9 urinary fistulae and 17 cases of ureteral obstruction. Urinary lithiasis was excluded from this work. Urinary fistulae occur almost only between the second week and the end of the first month. Ureteral obstructions occur relatively early (within 30 days in 14 cases and within the first 48 hours in 9 cases). Two grafts were lost (8% of complications, but 0.6% of the entire series), and one patient died following transplantectomy. In 10 of 26 cases (38.5%), the etiology of the urological complication was related to the harvesting technique (2 short ureters, 8 ischemic ureters).
