A mobile mass screening unit for prostatic disease

A mobile unit for mass screening of prostatic disease using transrectal ultrasonotomography was developed in December 1980. In the following years we screened 1,396 males over 55 years of age. We have detected 463 cases [33.2%] of benign prostatic hypertrophy [BPH] and eight cases [0.6%] of prostatic cancer. The detection rate of BPH and malignancy of the prostate was shown to be very high. Thus, the unit promises to be of value in preventative medicine projects for prostatic disease in Japan.
