Seventy-80% of prostatic carcinoma develops in the peripheral gland. Transrectal ultrasound (TRUS) has the capacity to identify nodules or hypoechogenic areas in the peripheral zone, suspected to be carcinoma. We describe a new echographic technic with endorectal probe (target compression test), to study hypoechogenic areas or nodules in the peripheral gland, during TRUS examination. Thirty-three patients, aged 49-77 years, with prostatic peripheral hypoechoic lesion at transrectal ultrasound, were studied. All patients underwent prostatic biopsy. Ten of the 11 positive patients (non compressible lesion) at the target compression test resulted to be affected by adenocarcinoma. Only 3 of the 22 negative patients (compressible lesion) at the target compression test resulted to be affected by adenocarcinoma. Even if our data have to be confirmed by further studies, they suggest that the target compression test may be a useful complementary test, during TRUS, in the evaluation of hypoechogenic areas in the peripheral gland.
