What is a rectal ultrasound?

An examination using high-frequency sound waves to create images of tissue layer beneath the surface of the rectum. A probe is placed into the rectum through the anal opening. A small amount of fluid is put into the tip of the probe so that the surface of the probe is touching the inside of the rectum. This allows for better visualization of the tissue. It is a safe painless procedure and no radiation is used.

About the Procedure

Depending on the reason for the ultrasound exam, an instrument called a proctoscope may be inserted into the rectum. The ultrasound transducer is then inserted either through the proctoscope or by itself.

A transducer sends and receives sound waves that are used to create images on the screen. An additional screen is usually available so that you may watch as the doctor carefully examines the area.

The ultrasound allows the physician to visualize and stage tumors. Additionally, he can analyze anal sphincter abnormalities and observe the path and depth of various anorectal abnormalities such as anal fistula.
