Sandwich Therapy

PNL followed by SWL is effective in the treatment of patients with multiple and or large renal stones. If the stone burden remains high, then a second percutaneous procedure is performed. This is an ideal treatment option for patients with complex stone disease, including large staghorn calculi. Sandwich therapy has proved to be equivalent to standard open nephrolithotomy with respect to preservation of renal function.
