摘要
Regardless of its relatively small size, the prostate is the most common site of pathology in human male, and the prostate is the site of the two most frequent medical problems affecting elderly men, benign prostatic hyperplasia （BPH） and prostate cancer （PCa）. Using the urethra as the key anatomical reference point, the prostate is conventionally divided into three distinct zones： peripheral zone, transition zone, and central zone. This morphology is of clinical significance in the development of age-associated conditions such as BPH and PCa.
