Use of a tamponade catheter in the bleeding nephrostolithotomy track.

Bleeding from the nephrostomy track, which is the most common major complication of percutaneous extraction of renal stones, was treated in 5 patients with the Kaye double-lumen nephrostomy tamponade catheter. This treatment was effective in all cases. The procedure eliminates the need for more invasive measures like embolisation and open surgery with renal resection, both of which cause loss of functioning renal parenchyma.
