Prostate - Sonography

The prostatic gland is located below the bladder anterior to the rectum. It is best viewable with an adequate bladder filling. We display it in two classic plains - longitudinal and transverse suprapubic projections.

 

The size of the prostate: We measure three proportions of the prostatic gland (the same procedure as by the urinary bladder) – anteroposterior, transversal and craniocaudal. The prostatic volume can be then counted by multiplying these values ​and then dividing it by two. The dimensions should be less than 45 (transversal) x 35 (anteroposterior) x 35mm (craniocaudal) and this gives the normal final volume of less than about 25 ml.

 

Prostate - sonography

Prostate tissue can be seen in a cross-section behind the urinary bladder.

Anteroposterior dimension is maximally 35mm and transversal is 45mm. 

 

 

Hyperplasia of prostate - The tissue is bigger than normal, the volume is greater than 25 ml. The gland is, however, homogeneous and well bordered.

 

 

Prostate hyperplasia - sonography

Hyperplasia of prostate - In this transverse projection we see hyperplastic

 prostatic tissue prominent toward the urinary bladder.

 

 

Calcifications of the prostate - They quite often accompany hyperplasia and prostate tumors. We see them as hyperechoic bright bearings.

 

Prostate calcifications - sonography

Calcifications of the prostate - in these pictures we see the prostate in both transverse,

and longitudinal sections. Apart the bright calcifications there is an evident hyperplasia of

the prostate (29.01 ml volume, prominence towards the urinary bladder)

 

 

Prostatic Cyst - Cysts sometimes occur without any significant underlying cause or they can be associated with prostatic hyperplasia. The cyst appears as a regular spherical anechoic formation. Cysts may be an incidental finding without any clinical symptoms or may be connected with recurrent prostatic infections.

a small anechoic cyst in the prostatic tissue.
