[Transcutaneous nephropyelostomy--indications, complications and results]

The authors report on 34 successfully applied nephropyelostomies in 30 patients. The most frequent indication was obstruction of the uterus with retention of substances usually eliminated in the urine. The operation was carried out under local local anesthetic using a monitor. The rate of complication was very low. No deaths resulted. In the authors' opinion puncture nephrostomy is the best method of drainage in causes of obstruction with benign genesis. For carcinoma patients it must be individually decided whether this operation is indicated.
