KLK3 and benign prostatic hyperplasia: In these analyses, PSA density after BPH surgery (Odds ratio [OR]: 0.684, 95% confidence interval [CI]: 0.469–0.997, p = 0.048) and suspicious lesion on mpMRI (OR: 11.827, 95% CI: 3.013–45.073, p = 0.001) constituted independent predictors of the presence of residual cancer at RP in both univariate and multivariate models.
