[Interventional radiology in the treatment of the complications from interventions on the lower urinary excretory tract].

Ureteral diversions may be complicated by strictures, hydronephrosis, pyelonephritis, lithiasis, fistulas, etc. In the last 10 years, 103 patients with 133 urological postoperative complications underwent percutaneous treatment. Most of the patients had been treated by percutaneous antegrade drainage; afterwards, stricture dilatation, ureteral stenting and stone extraction were performed. In one case a Strecker metallic stent was employed. We have successfully treated 101 of 133 complications (75.9%), with only 27 failures (20.3%). Five cases (3.8%) of lithiasis did not require percutaneous treatment. The good results obtained, the absence of major complications, the low cost and the little discomfort for the patients confirm the leading role of percutaneous treatment in complicated ureteral diversions.
