Minimum nephrostomy.

Abstract

A new type of nephrostomy is described with the following main characteristics: it uses a small multiperforated Silastic tube; its crosswise location allows perfect drainage of all of the calyces and the pelvis; it does not become obstructed nor move from its position; and it causes minimum traumatization of the renal parenchyma. It has a double purpose: its serves as a drain and safety measures as well as being used for the treatment of renal infection.
