[Screening of bladder cancer by a combination of transabdominal ultrasonography and urine cytology].
We evaluated the presence or absence of bladder cancer by a combination of transabdominal ultrasonography and urine cytology in 60 patients who had been suspected of having bladder cancer. All patients then underwent cystoscopy, and biopsy or resection if necessary, and 24 patients were diagnosed as having bladder cancer. By the combination of ultrasonography and urine cytology the diagnosis was correct in 23 patients accounting for 96% of sensitivity, and the misdiagnosis was made in only one patient who had undergone BCG therapy for carcinoma in situ but had submucosal invasive bladder cancer. Because of the high sensitivity rate, we believe that the combination of transabdominal ultrasonography and urine cytology should be the first-choice examinations for patients who are suspected of having bladder cancer.
