[Balloon ureter catheter for temporary endo-drainage (author's transl)].

A new balloon ureter catheter (catheter 7-French, balloon 9-French) is described. It offers important advantages over conventional catheters for temporary endo-drainage in the treatment of urinary obstruction as well as renal and ureteral fistulas. An angled whistle-tipped catheter facilitates placement. Sufficiently large drainage openings above and below the balloon and an additional outflow lumen prevent obstructions. The special catheter is held in an optimal position inside the balloon underneath the whistle tip. Thus, no further fixation is necessary, and the patients need not be confined to bed.
