Effects of parallel ultrasonic visualization of the prostate in sagittal and cross projections in transrectal biopsy on detectability of prostatic cancer

: The results of 526 transrectal prostatic biopsies are available. Mean age of the patients was 64.6 years, mean level of PSA--10.4 ng/ml, mean size of the prostate--56 cm3. Biopsy was made in visualization of the prostate in the sagittal projection (ultrasound devices Bruel & Kjaer 1846 and Kretz Voluson 730). Application of Bruel & Kjaer Medical 2102 Hawk provides visualization of the prostate during biopsy both in sagittal and cross projection. Double visualization significantly improved detectability of prostatic cancer in patients with PSA 4-10 ng/ml. In biopsy of the top and peripheral zone there was lengthening of prostatic tissue fragments, reduced fragmentation of the columns, less frequent blank shots of the biopsy gun. The data obtained supports the importance of isolated placement and marking of prostatic tissue fragments in biopsy and allow to recommend wide clinical use of ultrasonic facilities with biplanic sensors providing online sagittal and cross visualization of the prostate.
