Meta Analysis Comparative StudySupine Versus Prone Position in Percutaneous Nephrolithotomy for Kidney Calculi: A Meta-Analysis.
There are several positions in the operation of percutaneous nephrolithotomy (PCNL), such as prone position, supine position, flank position, and modified supine position for PCNL, but the supine and prone positions are the main two choices for several years. However, there is still discrepancy on the optimal position for PCNL. Therefore, we performed this meta-analysis to evaluate safety and efficacy of the supine versus the prone position in PCNL for renal calculi. ⋯ Compared with the prone position, the PCNL in the supine position has a slightly lower rate of stone clearance, albeit shorter mean operative time, and lower incidence of blood transfusions. The meta-analysis suggests that the PCNL in the supine position is a promising alternative.
