Transrectal ultrasonography

Transrectal ultrasonography is a medical imaging procedure that uses sound waves to create images of the rectum and nearby structures. It is commonly used in the diagnosis and treatment of conditions affecting the prostate, rectum, and lower gastrointestinal tract.

Procedure

The procedure involves the insertion of a small, lubricated probe into the rectum. The probe emits sound waves, which bounce off the tissues and organs in the body. These echoes are then converted into images by a computer. The images can be viewed on a monitor and saved for further analysis.

Uses

Transrectal ultrasonography is primarily used to evaluate the prostate gland. It can help detect abnormalities such as prostate cancer, benign prostatic hyperplasia, and prostatitis. It is also used to guide procedures such as prostate biopsy and brachytherapy.

In addition, transrectal ultrasonography can be used to assess the rectum and lower gastrointestinal tract. It can help diagnose conditions such as rectal cancer, anal fistula, and hemorrhoids.

Risks

Like all medical procedures, transrectal ultrasonography carries some risks. These may include discomfort or pain, bleeding, infection, and damage to the rectum or prostate. However, these risks are generally low, and the procedure is considered safe when performed by a trained professional.

Preparation

Before the procedure, patients may be asked to empty their bladder and bowel. They may also be given a laxative or enema to clean out the rectum. Patients should inform their doctor about any medications they are taking, as some may need to be stopped before the procedure.

Aftercare

After the procedure, patients may experience some discomfort or bleeding. They should contact their doctor if these symptoms persist or worsen. Patients can usually resume their normal activities immediately after the procedure.
