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.
Abdominal ultrasound examination of the prostate and kidneys is often performed to rule out hydronephrosis and hydroureter. Incidentally, cysts, tumours, and stones may be found on ultrasound. Post-void residual volume of more than 100 ml may indicate significant obstruction. [52] Prostate size of 30 cc or more indicates enlargement of the ...
The uvula can enlarge when the prostate becomes enlarged. The bladder is located below the peritoneal cavity near the pelvic floor and behind the pubic symphysis . In males, it lies in front of the rectum, separated by the rectovesical pouch , and is supported by fibres of the levator ani and of the prostate gland.
Common findings, determined by ultrasound of the bladder, include a slow rate of flow, intermittent flow, and a large amount of urine retained in the bladder after urination. A normal test result should be 20–25 ml/s peak flow rate. A post-void residual urine greater than 50 ml is a significant amount of urine and increases the potential for ...
The prostate is a gland that is found under the rectum and below the bladder in the male reproductive system. [5] Five randomized controlled trials were conducted to determine whether prostate cancer screening reduces mortality associated with prostate cancer where 341,342 participants within the age range of 45–80 years were included in the ...

IDCP associated with invasive carcinoma (IDCP-inv) generally represents a growth pattern of invasive prostatic adenocarcinoma while the rarely encountered pure IDCP is a precursor of prostate cancer. [20] The diagnostic criterion of nuclear size at least 6 times normal is ambiguous as size could refer to either nuclear area or diameter.
Prostate cancer is the most diagnosed cancer in men in over half of the world's countries, and the leading cause of cancer death in men in around a quarter of countries. [91] Prostate cancer is rare in those under 40 years old, [92] and most cases occur in those over 60 years, [2] with the average person diagnosed at 67. [93]
