Prone and supine percutaneous nephrolithotomy

Since the first successful stone extraction through a nephrostomy in 1976, percutaneous nephrolithotomy (PCNL) has became the preferred procedure especially for treatment of large, complex and staghorn calculi. For decades this method has been performed with the patient in the prone position. More recently, particular interest has been taken on supine PCNL due to less anestesiological risks and the possibility of simultaneous anterograde and retrograde access to the whole urinary tract. Although many retrospective studies have been published, only two prospective trials comparing the two positions are reported in the literature. The best access to PCNL represents still a controversial issue. The overall experience reported in literature indicates that each modality is equally feasible and safe. Therefore, to date the surgeon’s preference is the prime indication to one access over the other.
