ABSTRACT

The paper discusses the rules of the proper performing of the ultrasound examination of the prostate gland. It has been divided into two parts: the general part and the detailed part. The first part presents the necessary requirements related to the ultrasound equipment needed for performing transabdominal and transrectal examinations of the prostate gland. The second part presents the application of the ultrasound examination in benign prostatic hyperplasia, in cases of prostate inflammation and in prostate cancer. Ultrasound examinations applied in the diagnostics of benign prostatic hyperplasia accelerated the diagnosis, facilitated the qualification to surgery and the selection of the treatment method. The assessment of the size of the prostate gland performed using the endorectal ultrasound examination is helpful in making the choice between transurethral electroresection and adenomectomy. In prostate inflammation this examination should be performed with particular gentleness due to pain ailments. The indication for performing the examination in acute inflammation is the suspicion of prostate abscess. In chronic, exacerbating prostatitis it is possible to perform an intraprostatic antibiotic injection. In the recent years increased morbidity and detectability of prostate gland cancer is observed among men. In Poland it ranks second (13%) among diseases occurring in men. The indication for an endorectal examination is the necessity to assess the size of the prostate gland, its configuration, the echostructure in classical ultrasonography, the vascularization in an ultrasound examination performed with power doppler and, if possible, the differences in the gland tissue firmness (consistency) in elastography. The ultrasound examination is used for performing the mapping biopsy of the prostate gland – from routine, strictly defined locations, the targeted biopsy – from locations suspected of neoplastic proliferation and the staging biopsy – from the neurovascular bundles, the seminal vesicles, from the apex of the prostate and from the periprostatic tissue – this type of biopsy is supposed to help in determining local staging of the neoplastic disease. The ultrasound examination is also helpful during the treatment of the neoplasm performed using brachytherapy or using the method of ultrasonic ablation which is still in the phase of clinical trials.

The 3D transrectal USG examination: A. the peripheral zone on the right is hypoechogenic; the infiltration extends beyond the boundaries of the prostate. B. the hypoechogenic area on the left side of the prostate corresponds to a neoplastic infiltration; the integrity of the prostate capsule has been disrupted

B. the hypoechogenic area on the left side of the prostate corresponds to a neoplastic infiltration; the integrity of the prostate capsule has been disrupted

Mentions: The local staging assessment before the qualification for surgery is very important. The sensitivity and the specificity of this assessment are improved by three-dimensional ultra-sonography (USG 3D). The advantage of this type of examination over a classical endorectal ultrasound examination is based i.a. on the possibility to visualize suspected areas in various, freely chosen sections and on the fact that the examination consists of two stages. In the USG 3D examination the presence of the patient is required only during the acquisition of data (the first stage). The analysis of the images, the localization of the neoplastic infiltration, the assessment of the integrity of the prostate capsule, the assessment of the size of the neoplastic infiltration outside the capsule takes place in front of the computer, without the presence of the patient. This way more time may be devoted to this analysis and therefore – it can be more precise (Fig. 19, 20).
