Anal and Rectal 3D Ultrasound

This ultrasound lets your physician see the two sphincter muscles and if there is any damage.  It is helpful in evaluating incontinence, rectal pain & rectal lesions/tumors.  They can also detect tears, defects, gaps and scarring in the sphincter muscles. These images are displayed on a screen & photographs are taken.  The ultrasound only takes about 15 minutes. 

Anal ultrasound evaluates the structure of the sphincter muscle and surrounding tissue. Ultrasound is a very useful tool for imaging the anatomy of the internal and external anal sphincters.  To do this study, a wand-like probe is inserted into the anal canal and the rectum. This instrument, which is attached to a computer and video screen, emits sound waves. Using sound waves produced by the probe, images are captured on the screen. One of the more recent breakthroughs is the development of 3D Ultrasonography for this application.  It greatly improves visualization of surrounding structures and organs helping your doctor have a more 'complete' picture of the problem.  This technology is only available at very few centers in the country. 

Rectal ultrasound evaluates the rectal wall. The ultrasound probe, with a deflated balloon on the end, is inserted through the scope. The balloon is then inflated and cross-sectional images of the rectum are taken. This test helps evaluate rectal masses and aids in determining the appropriateness of various surgical alternatives.


  • Purchase two Fleet enemas from the drugstore.
  • Administer one enema the one hour before leaving your home.
  • Administer the second enema 30 minutes after the 1 enema, this one can be warm water. st
  • Take your regular medications on the morning of the procedure (e.g. for blood pressure).
  • You may eat the day of the test.
  • You may take scheduled medications at least 2 hours prior to the study with small sips of water.
  • Please empty your bladder prior to the exam.
  • You may drive yourself home after the test since no sedation is involved.
  • Bring the completed Bowel Questionnaire with you.
