Large studies of patients have also failed to show any correlation between lower urinary tract symptoms and a specific diagnosis. [11] Also, recently a report of lower urinary tract symptoms even with malignant features in the prostate failed to be associated with prostate cancer after further laboratory investigation of the biopsy.

A 2018 Cochrane review of studies on men over 60 with moderate to severe lower urinary tract symptoms analyzed the impacts of phosphodiesterase inhibitors (PDE) in comparison to other drugs. [90] These drugs may improve urinary symptoms slightly and reduce urinary bother but may also cause more side effects than placebo.
