Color Doppler sonography, Urinary bladder cancer
Color Doppler sonography was performed transabdominally in twelve patients with bladder tumor and ten candidates with normal bladder. Sixteen tumors were detected by cystoscopy and sonography, and were diagnosed as superficial bladder cancers by histopathology after transurethral resection. Tumor vessels were detected in two of 6 pedunculated papillary tumors less than 1 cm in diameter. Tumor vessels were observed within the tumor in eight cases with pedunculated papillary tumors of more than 1 cm in diameter. They were not found in two nonpedunculated papillary tumors. Normal bladder walls showed no Doppler color flow imaging. It was concluded that color Doppler sonography can improve the accuracy of tumor diagnosis by detecting tumor vessels, and may be used to distinguish pedunculated type from nonpedunclated type.
