Synchronous twin track percutaneous nephrolithotomy: A preliminary experience

Percutaneous nephrolithotripsy is the treatment of choice for large renal calculi. Total stone clearance as the treatment goal remains elusive, despite staged procedures and multiple tracks. There is also the morbidity of multiple sittings and tracks. We investigated the feasibility of a synchronized approach to clearing these difficult stones with two teams operating through two or more tracks in tandem and also the ergonomic and logistic issues involved.
