Complete Stone Clearance Using a Modified Supine Position: Initial Experience and Comparison with Prone Percutaneous Nephrolithotomy

Abstract

The modified supine position for PCNL has a number of advantages for the patient and staff compared with the prone position. Despite a more obese study group with larger stones, we have maintained stone clearance rates and significantly reduced operative time with no increase in complications. The technique has been easy to learn and teach. A major advantage has been simultaneous access to the lower urinary tract for ureteroscopy and stent placement, and this has helped with complete stone clearance.
