Bladder tumor, Mass screening, Prostatic diseases, Transrectal sonography
From 1975 to 1986, mass screening program for prostatic diseases using transrectal sonography for the primary study has been carried out on 5213 subjects. In this study, 4 cases of bladder tumor were detected in addition to prostatic diseases such as benign prostatic hypertrophy or prostatic cancer. In 3 cases of them, bladder tumor was visualized inside the bladder as a protrusion on the sonogram obtained with sufficient rilling of the bladder. In 1 cases, bladder tumor was not visualized on the sonogram at the primary study and was detected by preoperative examinations for benign prostatic hypertrophy.
