The predictive factors of fever after percutaneous lithotripsy

Objective To analyze the predictive factors of fever after percutaneous renal stone surgery, and to provide reference for clinical treatment. Methods A total of 147 patients underwent percutaneous nephrolithotomy in after operation was chosen in the Department of Urology in our hospital from January 2014 to January 2016. According to the existence of fever, patients were divided into fever (n=25, heating rate 17.0%) and control (n=122) groups. Preoperative information were collected, including age, gender, preoperative serum creatinine, stone size and shape, the involvement of calyceal number, water, urine culture results, operative time, blood loss, intraoperative perfusion volume, pyonephrosis, puncture channel length, hospitalization time and other information including intraoperative, postoperative information including fever, and postoperative renal fistula complications if there is information. SPSS 18.0 was used for statistical analysis. Results The fever group stone surface area, CT value affected calyx number, stone shape, stone properties, the involvement of calyceal number, degree of hydronephrosis, operative time, intraoperative blood loss, intraoperative perfusion, hospitalization time, and renal fistula complication rates were higher than the control group (P 0.05). The results of Logistic regression analysis found that the stone surface area (OR=5.19), stone, stone shape (OR=7.86) properties (OR=3.87), operation time (OR=5.68), intraoperative perfusion (OR=5.24), and renal fistula complications (OR=2.65) for the influence factors of fever. Conclusions The stone surface area is large, stone nature infection stones, stone shape for staghorn calculi, longer operation time, and intraoperative perfusion of large renal fistula complications were more prone to postoperative fever in postoperative.
