Eccentric nephroscopy for the incarcerated nephrostomy.
Following a percutaneous stone extraction and demonstration of antegrade flow, conventional methods of traction and coaxial dilatation failed to allow removal of a Stamey-Malecot nephrostomy. An eccentric track was created for nephroscopy. Grasping forceps were used to cut the fibrous tissue from the "wings" of the nephrostomy tube to allow its easy withdrawal. The combined approach by the radiologist and urologist safely overcame the fibrous entrapment.
