Identifying the causes of haematuria requires detailed clinical investigations. Unbalanced patient populations (mostly male) and diverse causes complicate patient classification and biomarker identification. Multi-marker analysis with advanced methods can improve diagnosis even in unbalanced datasets. We used k-means clustering, decision trees, random forest with LIME explainer, and CACTUS algorithm to classify patients as healthy (with no clear cause of haematuria) or sick (with an identified cause of haematuria e.g., bladder cancer, or infection). The CACTUS algorithm was more robust to dataset imbalance, achieving balanced accuracy of 0.747 for both genders, 0.718 for females, and 0.803 for males. Key biomarkers identified included microalbumin, male gender, and tPSA for the whole dataset; age, microalbumin, tPSA, cystatin C, BTA, HAD, and S100A4 for males; and microalbumin, IL-8, pERK, and CXCL16 for females. CACTUS outperformed decision trees and random forest, highlighting potential novel biomarkers for future diagnosis.
