[Surgical procedure and urologic complications after 922 kidney transplantations: our experience]. / Kirurski postupak i uroloske komplikacije nakon 922 transplantacije bubrega: nase iskustvo.

ABSTRACT

Between January 30 1971 and January 30 2011 922 kidney transplants were performed at our center, 360 (39%) from living related donor and 562 (61%) from cadaver. During first eight years an ureteroureterostomy was routinely used. The notable incidence of urological complications (fistula 11%, complications of stenting 10.7%, stenosis and lithiasis 4%) was observed after 140 transplantations. Majority of these complications (60%) were treated conservatively. A significant reduction in this incidence (P<0.001) was achieved (fistula 1,28%, complications of stenting 0,26%, lithiasis 0.12%) by introducing an extravesical ureteroneocystostomy by Lich-Gregoire. Stenosis had the highest incidence (4,23%). Majority of complications (76%) were treated surgically. A native ureter was commonly used in replacing the transplant ureter. In majority of patients an end-to-end pyelo(uretero)stomy was performed. Two patients were reoperated because of fistula, and the third had a prolonged healing. In last nine patients with urological complications an end-to-side pyelo(uretero)stomy was done. There was no urinary leakage. The safety of method results probably from an intact native ureter which has normal blood irrigation.
