[Management of ureteral stenoses and urinary fistulas following kidney transplantation].

The treatment of strictures and fistulas at the lower ureter after kidney transplantation was simple and could be achieved by reimplantation into the bladder. Proximal urinary fistulas caused early abdominal symptoms. The i.v. urogram showed a dilated renal pelvis without drainage into the ureter. The anatomical findings were in all cases strictures or total obstruction of the ureter beneath the pelvic junction and a rupture of the renal pelvis or calix. Adequate therapy consisted of ureteroureterostomy with the recipient ureter and nephrostomy splintage.
