TRANSRECTAL ULTRASONOGRAPHY IN THE EVALUATION OF BENIGN PROSTATIC HYPERPLASIA

One of the various problems in diagnosis and treatment of benign prostatic hyperplasia (BPH) is that the size of an adenomaa can notbe esti mated accurately in advance of surgery. Another problem is the difficulty in the diagnosis of BPH of an initial stage and therefore in predicting the surgical outcome in such a case. Transrectal ultrasonography developed by Watanabe was introduced in our clinic to solve these problems. Based on the findings of ultrasonographical morphology in 19 normal subjects and in 105 BPH patients who had TUR-P, the following conclusions are drawn: 1) The size of prostatic adenoma can be calculated by substracting the normal prostatic weight from the ultrasonographycally computed total weight, with considerable accuracy. 2) Ultrasonography enables us to diagnose BPH of an initial stage more easily and precisely than other conventional methods.
