Ultrasound is based on the properties of ultrasonic acoustic waves are. Ultrasound propagates in a straight line in a homogeneous structure. 

Their path is modified by the density and stiffness of the medium traversed. When in contact with an obstacle, the ultrasound echo return.

Ultrasound devices measure and analyze the echo intensity. They can produce cross-sectional images in all planes of space and analyze images in real time. It is through ultrasound that the doctor can see the movement of certain organs.

Ultrasound may be performed in any room, as long as it can be darkened to see better pictures. Ultrasound does not use, in fact, X-rays and, thus, no special protection is required. The ultrasound device like a computer, it includes a screen, a keyboard and probes that emit ultrasound. The probe is placed on the body part to be studied. Ultrasound conductive gel is applied to either the probe or on the skin.

Ultrasound is used to guide the puncture a gesture which will analyze the prostate tissue to confirm or not the existence of cancer.

Infections of the prostate resulting in an increase in volume of the gland by rectal examination.When the infection is severe, abscesses can be detected.

Finally, prostate ultrasound is useful for the assessment of male infertility whose origin may be related to a dysfunction of the gland or seminal vesicles that are attached.
