BEP can be diagnosed by a qualified physician by rectal examination, which suggests enlarged middle lobe of prostate most of the times. However, to confirm the diagnosis and to rule out malignancy of prostate, certain tests are required:
- Blood test to detect the level of PSA (Prostate Specific Antigen) which is raised above normal in cases of malignancy of prostate gland.
- Transrectal Ultrasonography gives an idea about size and contours of the prostatic overgrowth. In BEP, the contours are smooth while in malignancy, they are irregular.
- Microscopic and routine examination of the urine may suggest infection of the urinary tract in long standing cases of BEP.
- Urodynamic studies to analyse the flow of urine from the bladder.
