US-guided prostatic biopsy in 63 cases

Over a 20-months period, 63 patients with prostatic lesions less than or equal to 2 cm in size, detected at palpation or at ultrasonography (US), were followed-up with US-guided transperineal biopsy. Within the nodules located in the peripheral parts of the gland, and still confined within the capsule, focal cancer, chronic prostatitis and benign atypical hyperplasia were detected, but typical echo patterns were not seen. All nodules located in the periurethral gland were benign hyperplasia. US-guided biopsy in all patients presenting with small, suspicious nodules or focal echo pattern changes, localized within the peripheral gland, is recommended.
