Baten E, et al. – A prospective analysis was conducted to evaluate elevated or rising prostate specific antigen (PSA) as a marker for bladder outlet obstruction (BOO) in patients with minor lower urinary tract symptoms (LUTS) and without prostate cancer. The results confirmed that bladder outlet obstruction can cause an elevated or rising PSA in patients with minor LUTS and negative screening for prostate cancer. Remarkably, transurethral resection of the prostate is an adequate treatment for these patients.
