The study examined 170 eligible patients who had elevated total prostate specific antigen and/or abnormal digital rectal examination. Patients were divided into three groups for the procedure: The first group underwent TRUS-Bx with a B-K Type 8808 probe (circumference 58 mm) under injectable periprostatic anesthesia; the second group underwent TRUS-Bx with B-K Type 8551 probe (circumference 74 mm) under injectable periprostatic anesthesia; and group three underwent TRUS-Bx with B-K Type 8551 probe (circumference 74 mm) without local anesthesia.
Most of the patients in the first two groups experienced no pain or slight pain, but 66 percent of the patients in the third group had more than moderate pain. In the absence of local anesthesia, larger probe size results in much higher VAS pain perception than the same size and smaller under injectable local anesthesia.
