Definition Of Prostate Ultrasonography By Endorectal Approach

The ultrasound is a medical imaging technique based on the use of ultrasound, by which we can "see" inside the body. The ultrasound of the prostate, the gland just below the bladder in men and participating in the production of sperm, can be done in two ways:

For suprapubic: externally, by placing the probe above the pubis

By the endorectal route: internally, by introducing the probe into the rectum

Prostate ultrasound test in Delhi by the endorectal approach is more precise and allows to obtain a better image of the prostate. It also makes it possible to evaluate more precisely the volume of the gland as well as its "texture" and that of the accessory glands (seminal vesicles).

Why have an endorectal ultrasound?

Ultrasonography is a painless, non-invasive examination and is therefore first-line when the doctor suspects an abnormality in the prostate.

This can be the case:

  • After a rectal examination highlighting an abnormality (mass or hypertrophy) of the prostate
  • In case of urinary symptoms (frequent urge and emission of a small amount of urine, pain during urination, urinary tract infection, difficulty urinating, etc.)
  • In case of dosing showing an abnormal value of PSA (prostate antigen)
  • To diagnose Benign Prostatic Hypertrophy (BPH)
  • To guide the doctor when performing a biopsy and to help detect visually suspicious areas to better target specimens

However, endorectal ultrasound has no place in the diagnosis of prostate cancer because it is too inaccurate.

In addition to biopsies, ultrasonography is mainly used to assess prostatic volume, which tends to increase with age, which can lead to urinary discomfort (benign prostatic hypertrophy).

Examination

Ultrasound involves exposing the tissues or organs that one wishes to observe to ultrasonic waves. It does not require any preparation or anesthesia.

For endorectal ultrasound, an elongate (pencil-shaped) probe is used, covered with a condom and lubricated. It is inserted shallow into the anus, the patient lying on his side, knees bent. If a biopsy is performed at the same time, the doctor introduces a needle into the prostate, through the wall of the rectum, guided by ultrasound.

What results can be expected from an endorectal ultrasound of the prostate?

Whether it is to perform biopsies or to evaluate prostate volume, ultrasound clinics helps to diagnose prostate conditions, such as cancer (through biopsies) or benign prostatic hypertrophy. The choice of treatment will depend on the diagnosis but also the age of the patient, different risk factors, etc.

In the case of hypertrophy of the troublesome prostate, several drugs may be prescribed, including alpha-blockers and phytotherapy products (African plum or pygeum, saw palmetto).
