The Barts ‘Flank-Free’ Modified Supine Position for Percutaneous Nephrolithotomy

Abstract

Our results are encouraging and easily comparable with published series on prone position, Valdivia, complete supine and the Barts modified Valdivia positions. We would like to highlight the Barts 'flank-free' modified supine position as one of the standard positions for carrying out supine PCNL.
