Abstract:
Objective To analyze the correlation of preoperative collagen lectin-11(CL-11),urinary nitrite,and urinary heparin-binding protein(U-HBP)with postoperative urinary sepsis(US)in patients with kidney stones,and to explore their predictive value and warning significance for postoperative US.Methods A total of 190 patients with kidney stones who underwent minimally invasive percutaneous nephrolithotomy at the Second Affiliated Hospital of Kunming Medical University from September 2021 to June 2023 were selected.According to whether they developed US within 7 days after surgery,they were divided into the US group(n=30)and the non-US group(n=160).Baseline data and preoperative levels CL-11,urinary nitrite and U-HBP were compared between the two groups.The correlation between preoperative CL-11,urinary nitrite,U-HBP and postoperative US was analyzed.The predictive efficacy of preoperative CL-11,urinary nitrite,and U-HBP for postoperative US was evaluated.Results The positive rates of CL-11,urinary nitrite,and U-HBP in the US group were(313.68±38.73)ng/mL,46.67%and(157.82±41.61)ng/mL,respectively,which were higher than those in the non-US group at(234.00±41.25)ng/mL,12.50%,and(128.59±36.38)ng/mL(P<0.05).Logistic regression analysis indicated that preoperative CL-11,urinary nitrite,and U-HBP were influencing factors for the occurrence of US.The area under the curve(AUC)for predicting postoperative US was 0.797 for CL-11,0.624 for urinary nitrite,and 0.826 for U-HBP,while the combined AUC for predicting postoperative US was 0.923,with a sensitivity of 90.00%and specificity of 88.75%.Conclusion Patients with postoperative US following kidney stone surgery exhibited elevated levels of urinary nitrite,CL-11,and U-HBP,which were positively correlated with the occurrence of postoperative US.These markers have certain predictive value for postoperative US,and their combined detection offers superior predictive efficacy,potentially serving as warning biomarkers for postoperative US,thereby providing a reference for clinical prevention and control measures.
