Abstract:
Objective To investigate the diagnostic value Tamm-Horsfall protein(THP)and osteopontin(OPN)in serum and 24-hour urine for urolithiasis.Methods A total of 101 patients with urolithiasis who underwent flexible ureteroscopy lithotripsy at the Urology Department of Civil Aviation General Hospital from April 2020 to March 2023 were included as the stone group,and 50 healthy individuals were enrolled as the control group.The samples of serum and 24-hour urine samples were collected from both the groups,and the levels of THP and OPN were measured using enzyme-linked immunosorbent assay(ELISA).Logistic regression analysis was performed to evaluate the association between each biomarker and urolithiasis,and receiver operating characteristic(ROC)curves were plotted to assess their diagnostic value.Results The stone group showed significantly lower THP levels(20.13[13.12,26.03]mg/d)and OPN levels(51.24[36.72,101.37]μg/d)in 24-hour urine,and THP levels(182.01[160.91,209.20]ng/mL)and OPN lev-els(18.76[15.72,22.48]ng/mL)in serum compared to the control group(all the P＜0.001).Binary Logistic regression analysis re-vealed that THP(OR=0.736,95％CI:0.606-0.895),OPN(OR=0.975,95％CI:0.958-0.993)and citrate(OR=0.067,95％CI:0.012-0.376)in 24-hour urine,and THP(OR=0.946,95％CI:0.908-0.986)and OPN(OR=0.896,95％CI:0.803-0.999)in ser-um were the protective factors for urolithiasis,while calcium level(OR=2.125,95％CI:1.243-3.633)24-hour urine was a risk factor(all the P＜0.05).ROC curve analysis showed that the areas under the curve(AUCROC)for the individual diagnosis of urolithiasis were 0.846,0.809,0.786,0.823,0.748,and 0.755 for the above six biomarkers,respectively.The AUCROC for the combined diagnosis u-sing THP+OPN in serum,THP+OPN in 24-hour urine and all the six biomarkers were 0.882,0.920 and 0.984,respectively,indica-ting better diagnostic performance.Conclusion The combined detection of the THP and OPN levels in serum and 24-hour urine may have good diagnostic value for urolithiasis and serve as potential diagnostic biomarkers.
