A new method for percutaneous nephrostomy.

A new method of percutaneous nephrostomy using techniques to place a No. 12 French balloon catheter in the renal collecting system is described. Case reports demonstrate tumor palliation and temporary drainage to improve the very ill prior to definitive surgery. A translumbar aortogram catheter is placed lateral to paraspinous muscles and Dotter vascular dilators are used to allow insertion of the large balloon catheter.
