Simultaneous bilateral tubeless percutaneous nephrolithotomy: A report of 2 cases and review of the literature.

Percutaneous nephrolithotomy (PCNL) is currently the standard of care to remove large renal calculi. Traditionally, a large-bore nephrostomy tube is placed postoperatively. However, the necessity of this practice has been recently challenged. Theoretically, bilateral tubeless PCNL offers advantages of lower postoperative discomfort, shorter hospital stay and thus lower cost. We review the literature and present two cases of simultaneous bilateral tubeless PCNL from two patients who were referred to a tertiary stone centre from remote areas.
