The combined detection of HBP, ADPN, NGAL, and hs-CRP enables the construction of a highly efficient diagnostic model, offering a novel strategy for early infection identification and risk stratification after surgery.
This study investigated pathogen distribution, antimicrobial resistance, and the diagnostic utility of biomarkers (hs-CRP, HBP, NGAL, ADPN) for Urinary Tract Infections (UTI) after kidney stone surgery. A total of 130 patients with kidney stones, treated between February 2021 and December 2024, were included in this study. Based on the occurrence of postoperative UTIs, they were categorized into the UTI group (n=41) and the Non-UTI group (n=89). Laboratory parameters, including WBC, NLR, NEU, hs-CRP, HBP, NGAL, and ADPN levels, were measured. Midstream clean-catch urine samples from patients in the UTI group were collected for pathogen identification and antimicrobial susceptibility testing. Pearson correlation analysis was performed to assess the relationships among these biomarkers, ROC curve analysis was conducted to evaluate diagnostic performance, and logistic regression analysis was used to identify independent risk factors for postoperative infections.

| Pathogen Resistance Characteristics and Development of a Combined Diagnostic Model Using hs-CRP, HBP, NGAL, and ADPN for Postoperative Urinary Tract Infections in Patients with Kidney Stones | Postoperative UTI in kidney stone patients are primarily caused by Gram-negative bacteria with high resistance. Combined detection of hs-CRP, HBP, NGAL, and ADPN significantly improves diagnostic accuracy. HBP, NGAL, and ADPN serve as early predictive markers for postoperative infection, providing a reference for clinical practice. | 10 weeks |

A total of 130 patients diagnosed with kidney stones and treated at our hospital between February 2021 and December 2024 were enrolled in this study. Based on the presence of postoperative UTI, patients were categorized into the UTI group (n=41) and the Non-UTI group (n=89). The mean age of patients in the UTI group was 52.76±8.49 years, comprising 24 males and 17 females, whereas the Non-UTI group had a mean age of 53.03±7.12 years, including 43 males and 46 females.
