[Transperineal prostatic biopsy guided by ultrasound]

Thirty-three cases with clinical symptoms and signs suspecting prostatic cancer or other prostatic entities with abnormal ultrasonic reflection were diagnosed by transperineal prostatic biopsy guided by intrarectal ultrasonic probing. This procedure more accurate and safer than the conventional one. It seems quite useful clinically in the differential diagnosis of prostatic carcinoma, particularly the early cases from the other prostatic diseases.
