Obesity in percutaneous nephrolithotomy. Is body mass index really important?

Objective: To evaluate the influence of obesity in the results of percutaneous nephrolithotomy (PCNL) in terms of efficacy and safety and to evaluate other aspects such as fluoroscopy time, radiation exposure, total operative time, hemoglobin loss, hospital stay, and the need of auxiliary procedures.

Materials And Methods: We evaluated prospectively all the PCNLs performed at our institution between 2011 and 2012. A series of perioperative and postoperative details were recorded in our database.
