To determine the sensitivity of real-time abdominal ultrasound as a screening test to detect bladder tumors, a prospective study of 100 patients with painless hematuria was undertaken. Each patient was examined by excretory urography, bladder ultrasound, and cystoscopy. Results of the ultrasound and intravenous urography examinations were compared with cystoscopy results. Of 14 bladder lesions noted, ultrasound detected seven prospectively whereas intravenous urography detected 12. With awareness of the ultrasonographic appearance of bladder tumors, 12 lesions could be detected retrospectively. A fully distended bladder is necessary to avoid simulation of a neoplasm and false-positive ultrasound findings. Awareness of the cystosonographic appearance of bladder tumors may allow detection of asymptomatic tumors during routine pelvic ultrasound examinations.
为确定实时腹部超声作为检测膀胱肿瘤筛查试验的敏感性，对100例无痛性血尿患者进行了一项前瞻性研究。每位患者均接受排泄性尿路造影、膀胱超声和膀胱镜检查。将超声和静脉尿路造影检查结果与膀胱镜检查结果进行比较。在发现的14处膀胱病变中，超声前瞻性地检测出7处，而静脉尿路造影检测出12处。了解膀胱肿瘤的超声表现后，可回顾性地检测出12处病变。膀胱充分充盈对于避免肿瘤假象及超声检查假阳性结果很有必要。了解膀胱肿瘤的超声表现可能有助于在常规盆腔超声检查时发现无症状肿瘤。
