[Treatment of ureteral obstruction by a double pig-tail catheter. Our experience]

The authors' experience is based upon 39 patients treated for ureteric obstruction between March 1980 and March 1984. The obstruction was of neoplastic origin in 7 cases. In 5 cases the double pig tail catheter was inserted peroperatively as a urinary drainage method. The catheter was inserted endoscopically in 10 cases and percutaneously in 9 cases. In 15 cases a temporary or permanent nephrostomy was necessary. Indications and complications of the method are analysed and the results compared with those in the literature.
