Also known as "sonogram", is a painless procedure using reflected sound waves to produce images of the organs. In urology, it can be used for bladder, kidney, prostate, scrotum and testicular ultrasound scanning.

 

A water-based gel is spread on the skin over the part to be examined, to help transmit the sound waves. A hand-held transducer moves over the part to produce images for size, position and check for bladder draining. It may also be used to check for blockages, stones or tumours.

​

No fasting or bowel preparation is needed for this procedure.
