The levels of PSEP and HSP70 in urine were detected by enzyme\u2010linked immunosorbent assay. The differences in urine PSEP and HSP70 levels between the groups were analyzed, and receiver operating characteristic (ROC) curves were used to analyze the clinical value of PSEP and HSP70 in the diagnosis of CP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The PSEP levels of CP patients were significantly higher than those of the control group (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001), but there was no difference in PSEP levels among CP subgroups. The level of HSP70 in the urine of the NIH\u2010II patients was significantly lower than the levels in the NIH\u2010IIIa and NIH\u2010IIIb subgroups and the control group, but there was no difference in HSP70 levels between the NIH\u2010IIIa and NIH\u2010IIIb subgroups and the control group. ROC curve analysis results showed that the area under the curve (AUC) of PSEP for the NIH\u2010II, NIH\u2010IIIa, and NIH\u2010IIIb patients was 0.751, 0.776, and 0.731, respectively.
