Transrectal Ultrasonography

Transrectal ultrasonography (TRUS) is a diagnostic medical imaging technique used primarily to visualize the prostate gland and surrounding tissues. It involves the use of an ultrasound probe inserted into the rectum to obtain detailed images of the prostate and is commonly used in the evaluation of prostate conditions, including prostate cancer.

Procedure

The procedure is typically performed with the patient lying on their side with knees bent. A lubricated ultrasound probe is gently inserted into the rectum. The probe emits sound waves that bounce off the prostate and surrounding tissues, creating echoes that are converted into images by a computer. These images are displayed on a monitor and can be used to assess the size, shape, and texture of the prostate.

Uses

Transrectal ultrasonography is used for several purposes, including:

Prostate Cancer Detection: TRUS is often used in conjunction with a prostate biopsy to detect prostate cancer. It helps guide the biopsy needle to specific areas of the prostate.
Prostate Volume Measurement: It provides accurate measurements of prostate volume, which is important in the diagnosis and management of benign prostatic hyperplasia (BPH).
Guidance for Procedures: TRUS is used to guide certain procedures, such as the placement of brachytherapy seeds for prostate cancer treatment.

Advantages and Limitations

TRUS is a minimally invasive procedure that provides real-time imaging and is generally well-tolerated by patients. However, it has limitations, including:

Limited Field of View: The probe's position in the rectum limits the field of view to the posterior and lateral aspects of the prostate.
Operator Dependency: The quality of the images and the accuracy of the procedure can depend on the skill and experience of the operator.

-== Risks ==
+TRUS is a minimally invasive procedure that provides real-time imaging and is generally well-tolerated by patients. However, it has limitations, including:
-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 ==
+* '''Limited Field of View''': The probe's position in the rectum limits the field of view to the posterior and lateral aspects of the prostate.
-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.
+* '''Operator Dependency''': The quality of the images and the accuracy of the procedure can depend on the skill and experience of the operator.
-== Aftercare ==
+== Related Pages ==
-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.
