ABSTRACT
Objective To evaluate and study percutaneous nephrolithotomy (PCNL) related factors in the treatment of renal calculi caused postoperative fever and its prevention measures. Methods Making a retrospective analysis of the clinical records of 150 patients who underwent PCNL, including age, gender, diabetes history and previous ipsilateral renal surgery, stone type, stone size, whether the complication of upper ureteral stones, preoperative urinary tract infection, hydronephrosis and pyonephrosis, preoperative renal fistula, postoperative centering vein pressure, intraoperative perfusion and the operation time from January 2015 to June 2017. After the operation, the patients were divided into two groups: fever group and non-fever group, and analyzed the related factors of the fever. Results Among the 150 cases, fever occurred in 27 cases after PCNL, taking up 18%. Gender, history of diabetes, staghorn calculi or staghorn stone, stone size, with ureteral calculi, preoperative urine leukocyte count, renal abscess, preoperative renal fistula, postoperative central venous pressure, intraoperative perfusion and operation time between the two groups, the differences that were statistically significant (P < 0.05). Logistic that multivariate analysis showed that female patients with upper ureteral calculi, perfusion, intraoperative volume,preoperative pyonephrosis, long operation time are independent risk factors of fever after operation (OR
