AUA 2011 - Renal and perirenal anatomy in the supine and prone position: implications for percutaneous stone treatment - Session Highlights

WASHINGTON, DC USA (UroToday.com) - Debate continues to reign as to the safety and efficacy of supine versus prone position PCNL.

Radiologic imaging with CT scan shows significant changes in the positioning of adjacent organs, such as liver, spleen and colon when the patient is in the prone versus supping position. These researchers suggested a greater risk, in the prone position, of transpleural puncture on either side and possibly greater risk of transcolonic puncture during left lower pole access. However, the International Cooperation in Endourology compared supine versus prone PCNL in 350 obese patients and found high success rates for both approaches and clinically similar and low complication rates.

So while theoretically one positioning may have advantages or disadvantages for PCNL, in reality it would appear that with adequate training and experience both the supine and prone PCNL are equivalent in rendering the patient stone free and with minimal operative complications.
