To describe color Doppler ultrasonography findings of bladder tumors and to investigate the correlation between these findings with stage and histopathological grade.
Twenty-four patients with bladder tumors were assessed with color Doppler ultrasonography for tumor size, presence of vascularity, vascular pattern, and spectral properties. All patients underwent surgery. Stage and histopathological grades of tumors were determined and compared with color Doppler ultrasonography findings.
Presence of vascularity was related to tumor size (P<0.05) and color Doppler signal was detected when tumors reached 24 mm in size. There was no statistically significant relationship between tumor stage and histopathological grade with tumor size, presence and pattern of vascularity, and spectral color Doppler ultrasonography findings (P>0.05).
The evaluation of vascularity in bladder tumors by color Doppler ultrasonography is not helpful in predicting tumor stage and histopathological grade before surgery.
描述膀胱肿瘤的彩色多普勒超声检查结果，并探讨这些结果与分期及组织病理学分级之间的相关性。
对24例膀胱肿瘤患者进行彩色多普勒超声检查，评估肿瘤大小、血管情况、血管形态及频谱特征。所有患者均接受手术治疗。确定肿瘤的分期和组织病理学分级，并与彩色多普勒超声检查结果进行比较。
血管情况与肿瘤大小相关（P<0.05），肿瘤大小达到24 mm时可检测到彩色多普勒信号。肿瘤分期和组织病理学分级与肿瘤大小、血管情况及形态、彩色多普勒超声频谱结果之间无统计学显著相关性（P>0.05）。
术前通过彩色多普勒超声评估膀胱肿瘤的血管情况对预测肿瘤分期和组织病理学分级并无帮助。
