This study was aimed to retrospectively analyze the potential of non-invasive serum biomarkers in clinically predicting the detrusor underactivity (DU) in benign prostatic hyperplasia (BPH) patients with lower urinary tract symptoms (LUTS) and low prostate volume (PV). The study enrolled 196 patients with BPH and LUTS at our hospital in the period from January 2018 to October 2023. The patients were divided into two groups based on the projected isovolumetric pressure (PIP): the DU and the control groups. The patients included in the study had PV of less than 50 mL. A total of 93 and 103 cases were placed in the DU and control groups, respectively. Univariate analysis exhibited that the age was associated with DU occurrence (p = 0.004), and the serum prostate specific antigen (PSA) might act as DU protective factor (p = 0.001). However, there was no statistically significant relation between pre-selected serum hematological parameters and the DU diagnosis accuracy. Multivariate analysis suggested that only the age (OR (odds ratio) 1.07, 95% CI (confidence interval) 1.03–1.12, p = 0.001) and PSA (OR 0.79, 95% CI 0.69–0.90, p < 0.001) were the independent predictors of DU. In this study, it was observed that the pre-selected serum hematological parameters had no relevance in diagnosing DU in low PV male patients. Nonetheless, it was found that the age and PSA could be the independent non-invasive predictors of male patients with LUTS and low PV, who were unable to undergo urodynamic examinations.
