Prostatic biopsy with the 21 gauge Surecut needle. A preliminary report of a new technique.

The 21 gauge Surecut needle is a fine needle system providing regular tissue cores for histological evaluation. Using the Franzén needle sheath, transrectal biopsies were performed on 13 patients and a tissue core obtained in 12 cases. Ultrasonically guided transperineal biopsies were performed on 14 patients and a tissue core was obtained in 13 cases. It is concluded that the 21 gauge Surecut needle is able to yield histological material for prostatic diagnosis.
