Problem: Infectious complication after percutaneous nephrolithotomy (PCNL) represents a dangerous and life-threatening condition, especially when septicemia or septic shock develops. It usually occurs with persisted fever more than 24 hours after the operation.
Objective: To identify factors associated with persisted fever more than 24 hours after percutaneous nephrolithotomy.
Material and Method: One hundred and three patients underwent PCNL in 2 years in our institute. Patient characteristics, stone burden, and perioperative data were collected to analyze for association with postoperative fever using univariate analysis.
Result: Twenty-four percent of the patients developed fever more than 24 hours after the operation. In univariate analysis, significant association was shown between fever and positive immediate preoperative urine culture (p = 0.049), and between fever and intraoperative surgical complication such as bleeding and perforation of renal pelvis (p = 0.023).
Conclusion and Benefit: Positive preoperative urine culture and the presence of intraoperative surgical complication significantly increase the risk of infectious complication after PCNL. Patients with these factors should be monitored closely after the operation to identify and threat infectious complication immediately.
