Using a new type of equipment for transrectal ultrasonotomography 174 human subjects with or without prostatic diseases were examined.
The results obtained were as follows:
1) It was found from our investigation that transrectal scanning was the most accurate method for the estimation of prostatic size and weight. Measurements in normal subjects and cases of Klinefelter's syndrome, prostatic hypertrophy and prostatic cancer were shown in Table 2.
2) It became clear that digital examination had some drawbacks to estimating accurate prostatic size.
3) As a rule, a basic shape of the normal prostate on horizontal section showed a symmetrical triangular pattern. On the other hand, the typical hypertrophic prostate had a symmetrical round pattern and the cancer prostate had an asymmetrical semilunar or round pattern.
4) The distribution of echo spots inside the prostatic region was regular in usual cases and irregular in most cancer cases.
5) The continuity of echo pattern from prostatic capsule was also regular in usual cases and irregular in most cancer cases. This irregularity was thought to be due to cancer infiltration.
6) The staging of prostatic cancer by palpation was occasionally not strict as compared with that by ultrasonotomography.
