[Percutaneous nephrostomy under ultrasound guidance (author's transl)].

34 ultrasonically guided percutaneous nephrostomies were performed without complications. The procedure seems to be applicable in routine clinical use for temporary or permanent urine diversion in hydronephrotic kidneys. The simple technique the low complication and high success rate and independence of kidney function make the technique superior to the standard methods of the percutaneous puncture under radiological control.
