Ultrasonography is widely performed for screening of diseases in the upper abdomen. From April, 1985 to March, 1987, we carried out transabdominal ultrasonography of the entire abdomen for screening all the abdominal and pelvic diseases in the regular health check-up. Thirty-four cases out of 16, 377 screened patients were ultrasonographically suspected of bladder tumor and received cystoscopic examination. Cystoscopy confirmed bladder tumors in 26 out of the 34 cases. Six among the 26 patients showed no urological symptoms and were seen as nonurological outpatients. Four of them revealed transitional cell carcinoma of low grade and low stage, while the rest of them transitional cell papilloma. The smallest tumor detected by ultrasonography was 3mm in diameter.
Transabdominal ultrasonography of the entire abdominal organs proved useful for diagnosis of the bladder tumor at the early stage in the mass screening. Therefore, it is recommended to perform the lower abdominal scanning at the time of the ultrasonographical abdominal examination.
