Core Tip

Core Tip: Percutaneous nephrolithotomy (PNL) is the first line of treatment for large kidney stones. Although the complication rates are usually low, they may warrant hospital readmission (HR) in the convalescence course of patients undergoing PNL. The overall stone-free rate was 88.8%, and the total complication rate was 32.3%. The highest grade of complications was IIIa by the modified Clavein grading system, resulting in an HR rate of 22.4%. Several preoperative, operative, and postoperative variables may be associated with increased HR after PNL. However, only the preoperative pyuria, intraoperative injury, and inadequate instructions on urethral catheter care were independently associated with HR.
