The exam is generally performed in the doctor’s office, in the clinic or as an external consult in hospital. The exam lasts between 15 and 30 minutes.
No special preparation is needed before prostate ultrasound. The man is covered with a sheet during the intervention. He usually is lying on his left side, with his knees folded up to his thorax. We put a protective cover and lubricant on the ultrasound probe before inserting it into the rectum. The man may feel some pressure or have a feeling of fullness in the rectum when the transducer is in place. The transducer emits high frequency sound waves to the prostate. A computer analyses the echoes generated by the sound waves and produces images of the prostate on the screen. The image reveals the size of the prostate and any abnormalities.
