Biomarkers, kits and systems for diagnosing prostate hyperplasia secondary bladder damage

PendingCN122130952AEnsemble learningBiological testingBladder injuryUrine sample
This invention discloses a biomarker, reagent kit, and system for diagnosing bladder injury secondary to benign prostatic hyperplasia (BPH), relating to the field of biomedical detection technology. The biomarker for diagnosing bladder injury secondary to BPH is characterized in that it includes urinary DAB2 protein. This invention achieves (1) clinical applicability: accurate quantitative assessment of the degree of injury. The most significant clinical value of urinary DAB2 protein lies in its ability to transform traditional subjective bladder injury assessment into an objective quantitative indicator. (2) convenient detection: non-invasive and rapid assessment using urine samples. As a urine detection biomarker, urinary DAB2 protein completely changes the traditional bladder injury assessment's reliance on invasive or expensive examinations such as cystoscopy and CT. (3) clinical decision support: the grading diagnostic value of urinary DAB2 protein is directly translated into clinical decision support capabilities, helping to avoid the clinical dilemma of "overtreatment" or "undertreatment."
