Significant hemorrhage from the access site is an infrequent complicat
ion of percutaneous renal surgery, We developed a novel nephrostomy tu
be that combines the benefits of the re-entry Malecot design with thos
e of the Kaye tamponade catheter. The new nephrostomy tube was success
ful in preventing significant bleeding in high-risk patients who had t
his tube placed after percutaneous nephrostolithotomy, All of the pati
ents tolerated the tube without complications, Preliminary results sho
w that this tube is easy to insert, well tolerated by patients, and ef
fective in preventing and stopping bleeding from a percutaneous access
site and that it maintains ureteral access.
