Transrectal ultrasonography of the prostate
Transrectal ultrasound (TRUS) is a fast outpatient procedure that uses ultrasound to create an image of the prostate gland. A small, lubricated probe connected to the ultrasound machine is placed into the rectum to visualize the prostate.
This is performed to detect disorders within the prostate, determine whether the prostate is enlarged and its size and volume, detect any abnormal growth within the prostate, and in male infertility assessment when there is suspicion of ejaculatory duct obstruction.
