Transrectal Ultrasound & Prostate Biopsy

Transrectal Ultrasound and Prostate Biopsy is done to confirm whether you have prostate cancer, after the digital rectal exam and PSA test. 
During a transrectal ultrasound (TRUS), the sensor of an ultrasound machine is placed into the rectum that produces and detects sound waves that bounce off the prostate gland. The pattern of the sound waves creates a picture of the prostate gland on the screen that can help locate areas of abnormal tissue.

TRUS can also be used to help a doctor guide a needle to the correct spot in the prostate gland for collecting a tissue sample (biopsy). Usually 6-8 samples of different parts of the prostate are collected. The tissue is then examined for cancer by a pathologist. After the biopsy, some blood may be seen in the urine or stool for a day or two.

There is a possibility of getting an infection in the prostate after the biopsy, usually antibiotics are prescribed to prevent this.
