Use of Stone Cone minimizes stone migration during percutaneous nephrolithotomy.
We describe a simple and effective method using the Stone Cone to prevent migration of stone fragments into the ureter during percutaneous nephrolithotomy. This maneuver may reduce the need for antegrade ureteroscopy to remove residual fragments, thereby saving time and obviating the need for placement of an occlusion balloon.
