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 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.
The urinary flow rate in males with benign prostate hyperplasia is influenced, although not statistically by voiding position. In a meta-analysis on the influence of voiding position in males on urodynamics, males with this condition showed an improvement of 1.23 ml/s in the sitting position. Healthy, young males were not influenced by changing ...

The Charrière is measured by the ''outer'' diameter, and is defined as 1 Fr = 1/3 mm, and thus 1 mm = 3 Fr; therefore the diameter of a round catheter in millimetres can be determined by dividing the French size by 3. [2] The French units roughly correspond to the outer circumference of the catheter (see table below).
