With respect to postoperative f-UTIs and sepsis, multivariable analyses were performed for patient age, BMI, surgical hand hygiene, preoperative CRP, pyuria, WBC count, operation time, postoperative indwelling ureter stent, and nephrostomy using logistic regression analysis. Regarding URS and ECIRS, multivariable analyses were performed to compare above perioperative f-UTIs and sepsis in surgical hand hygiene, operation time, total stone size, and the preoperative and/or postoperative indwelling of ureter stent and nephrostomy. A p value < 0.05 was considered statistically significant.
