TL;DR

In elderly patients undergoing PCNL, prolonged OT was independently associated with higher odds of overall, major, and infectious postoperative complications, supporting OT as a practical intraoperative marker for risk stratification and procedural planning.

Abstract

To evaluate the association between operative time (OT) and postoperative complications after percutaneous nephrolithotomy (PCNL) in elderly patients, and to identify a clinically meaningful OT threshold for risk stratification.
