title: [Treatment of ureteral obstruction and urinary fistulas after kidney transplantation].
abstract: In 285 renal transplantations, performed during the years 1967-1978, 6 ureteral obstructions (2,1%) and 15 urinary fistulas (5,3%) were observed. Ureteral obstructions occurred in the late phase after transplantation and were caused by strictures at the uretero-vesical anastomosis (two patients), compression of the ureter by enlarged kidney during rejection (one patient) resp. lymphocele (one patient) and strictures at the pyelo-ureteral junction (two patients). Satisfactory results were achieved by surgical treatment in all patients. Urinary fistulas occurred in the early postoperative phase. Two vesical, 12 vesico-ureteral and one calyceal fistula were observed. 7 fistulas (1 vesical, 6 vesico-ureteral) closed spontaneously after temporary drainage of the bladder. 8 fistulas were repaired surgically. While satisfactory results were obtained in 13 patients, two patients died due to infection and sepsis after reoccurrence of fistulas.
