Abstract:Objective: To study the relative independent risk factors of sepsis caused by percutaneous nephrolithotomy (PCNL) in patients with upper urinary calculi in order to provide objective basis for perioperative period and promote the early diagnosis and treatment of urinary sepsis, and establish nomogram prediction model of independent risk factors. Methods: The clinical data (sex, age, BMI, history of diabetes, stone size, stone number, stone location, stone CT value, stone load, operation time, previous urological surgery history, preoperative urine culture, urine leukocyte, urinary nitrite, platelet count, eosinophil count) of 260 patients undergoing PCNL in our hospital from January 2014 to March 2019 were retrospectively analyzed. The independent risk factors of urinary sepsis after PCNL were evaluated by univariate and multivariate Logistic regression analysis. According to the Logistic regression coefficient, we drew the corresponding nomogram prediction model. Results: According to the results of multivariate Logistic regression analysis, the independent risk factors related to progression to urinary sepsis after PCNL included: diabetes history (OR = 4.394, P = 0.014), stone load (OR = 2.968, P = 0.021), operation time (OR = 2.872, P = 0.008), preoperative urine culture (OR = 3.390, P = 0.011), urinary nitrite (OR = 2.961, P = 0.018).The consistency coefficient C-statistics of the prediction model is 0.915, and the Hosmer-Lemeshow test hint(χ² = 0.973, P = 0.856) revealed that the new prediction model had good discrimination and calibration. Conclusions: Diabetes history, stone load, operation time, preoperative urine culture, and urinary nitrite are relatively independent risk factors for urinary sepsis after PCNL. The nomogram prediction model established is helpful to predict the incidence of urinary sepsis after PCNL, and is also beneficial to the early prevention, treatment, and diagnosis of sepsis.
