OBSERVATIONAL
Summary
The aim of this study is to investigate the effect of different surgical positions (supine/prone) on lung mechanical power (MP) and its relationship with postoperative pulmonary complications in patients planned to percutaneous nephrolithotomy (PNL) under general anesthesia.

Interventions
Mechanical Power= 0.098×Minute ventilation× (peak pressure - 0.5 (plato pressure-PEEP)). These parameters are monitored on the monitor while the patient is mechanically ventilated and placed into the equation
