Complications of Percutaneous Nephrolithotomy Classified by the Modified Clavien Grading System: A Single Center's Experience over 16 Years

Abstract

The modified Clavien classification provides a standardized grading system for complications of PCNL, although consensus on specific complications would prompt better comparison between centers. A shorter operation time is imperative to achieve less bleeding. Previous stone-related fever and staghorn stones are significant contributing factors for developing postoperative fever.
