Description
The prostate is a part of the male anatomy. It surrounds the urethra, and lies immediately inferior to the urinary bladder. There is no analogous structure in female anatomy.
Structurally it is a chestnut-shaped bulb divided into concentric zones around the urethra. The prostate is comprised of approximately 30% glandular and 70% fibromuscular stromal elements. Common diseases include: Prostate cancer, prostatitis, BPH, prostatism, and less commonly abscess. Diagnostic evaluation is initially via rectal examination and the evaluation of a blood test called the PSA – prostate specific antigen. Common modalities used for imaging the prostate include: Ultrasound, MRI, CT scan.
Treatments Medical treatment includes the use of hormonal agents, antibiotics, and chemo therapy although in severe disease surgery and radiation are commonly employed.
