Predictive value of IPS score combined with ALB,PLT,Lac for postoperative urinary sepsis in patients with renal stones
Objective To explore the predictive value of infection possibility score(IPS)combined with albumin(ALB),platelet count(PLT)and lactic acid(Lac)levels for urogenic sepsis after percutaneous nephrolithotomy lithotripsy in patients with renal calculi.Methods From January 2019 to February 2021,212 patients with renal calculi treated by percutaneous nephrolithotomy litho-tripsy in Baoji Central Hospital were selected as the research object.According to whether the patients were complicated with urogenic sepsis after operation,they were divided into concurrent group(24 ca-ses)and non concurrent group(188 cases).The IPS scores and the levels of ALB,PLT and Lac pre-operative and postoperative were compared between the two groups.Logistic regression analysis were used to analyze the influencing factors of urinary sepsis after percutaneous nephrolithotomy lithotripsy in patients with renal calculi,and the receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of IPS score combined with the levels of ALB,PLT and Lac for urinary sepsis after renal calculi operation.Results The proportion of preoperative positive urine culture,postoperative IPS score and Lac level in the concurrent group were higher than those in the non-concurrent group,while the postoperative ALB level and PLT were lower than those in the non-concurrent group(all P＜0.05).Logistic regression analysis showed that preoperative urine culture positive,and postoperative IPS score and Lac level inceeased,ALB and PLT levels decreased were all risk factors of urinary sepsis after kidney stone surgery(all P＜0.05).ROC results showed that the sensitivity and area under the curve(AUC)of postoperative IPS score combined with ALB,PLT and Lac in predicting postoperative urogenic sepsis of renal calculi were higher than those predicted alone(all P＜0.05),and there was no significant difference between specificity and prediction alone(P＞0.05).Conclusions Positive preoperative urine culture,postoperative IPS score and Lac level increased,ALB and PLT levels de-creased are all risk factors for urinary sepsis after percutaneous nephrolithotomy lithotripsy in patients with renal calculi.The postoperative IPS score,ALB,PLT and Lac levels have a certain predictive value for urinary sepsis after renal calculi surgery,but the combined predictive value of the four is higher.
