Emergency percutaneous nephrostomy in supine-oblique position without cushion.

The most frequent cause of obstructive uropathy with sepsis is ureteral lithiasis. Normally, two positions are used for placement of percutaneous nephrostomy: prone position and supine position. We describe a supine-oblique position without cushion consists of placing the patient in lateral position while we lean him until his back is in a 45° angle with the operating table to perform the percutaneous nephrostomy. Our experience since 2005 with 42 procedures is good, with 100% of success and without important complications.
