The prostate is a exocrine gland of the male reproductive system. In adults, it is about the size of a walnut, [2] and has an average weight of about 11 grams (0.39 oz), usually ranging between 7 and 16 grams (0.25–0.56 oz). [3] The prostate is located in the pelvis. It sits below the urinary bladder and surrounds the urethra.
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland. [1] Symptoms may include frequent urination , trouble starting to urinate, weak stream, inability to urinate , or loss of bladder control . [ 1 ]

It is responsible for producing fluid that helps with sperm movement. Due to its location within the body, when diseased, it can affect the reproductive and urinary systems. [3] Prostate diseases, such as prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer all affect the functioning of this gland. [9] [10]
Pattern 1 - The cancerous prostate closely resembles normal prostate tissue. The glands are small, well-formed, and closely packed. This corresponds to a well differentiated carcinoma. Pattern 2 - The tissue still has well-formed glands, but they are larger and have more tissue between them, implying that the stroma has increased. This also ...
Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
