title: Fistulas of the upper urinary tract: percutaneous management.
abstract: We treated 40 patients with urinary fistulas by interventional radiology. The antegrade percutaneous route, catheterization of the ureter and bypassing of the fistula enabled ureteral stenting in 36 patients (90 per cent). Criteria for successful treatment were healing of the fistula, normal renal function (evaluated by excretory urography and radionuclide studies) and absence of secondary stenosis at 6 months. Of the patients 28 (70 per cent) were treated successfully. The number of nephrectomies after failure of percutaneous techniques (5 of 40, or 12.5 per cent) seems lower than in the case of surgery. The results were excellent for fistulas occurring after endourology (all 9 successful) or after ureterointestinal anastomoses (7 of 8). On the other hand, the results appear disappointing in patients with fistulas in transplanted kidneys (3 of 4 failures).
