Access related complications during percutaneous nephrolithotomy: urology versus radiology at a single academic institution.

Purpose: A recent survey revealed that only 11% of urologists performing percutaneous nephrolithotomy routinely obtained percutaneous access themselves. Reasons for this trend may include lack of training, comfort level and perceived need for radiological involvement. In this study we evaluated percutaneous access for percutaneous nephrolithotomy obtained by interventional radiologists or a urologist at a single academic institution, and compared access trends and complications.
