摘要
目的探讨脐尿管癌的二维及彩色多普勒超声特点。方法对14例脐尿管癌肿块的二维及彩色多普勒血流显像(CDFI)特点进行回顾分析,并选取同期位于相同部位(膀胱前壁或顶部)的18例膀胱移行上皮癌的肿块进行比较分析。所有病例均经手术及病理证实。结果所有病灶均为不均质的低回声肿块,形态不规则,14例脐尿管癌肿块均单发、位于脐尿管下段,无蒂或宽蒂,浸润膀胱黏膜8例,伴钙化4例,囊性变3例;18例膀胱移行上皮癌肿块有5例多发,蒂细或宽,伴钙化5例,囊性变1例;CDFI肿块内均可探及血流信号,脐尿管癌的血流分布以周边型为主,占71.43%(10/14),中央型占7.14%(1/14),混合型占21.43%(3/14),膀胱移行上皮癌的血流分布以中央型为主,占72.22%(13/18),周边型占11.11%(2/18),混合型占16.67%(3/18),两组间血流分布类型比较有显著性差异(χ2=15.36,P<0.05)。结论 CDFI是诊断膀胱肿瘤的一种重要方法,血流信号的分布类型在脐尿管癌和膀胱移行上皮癌鉴别诊断上有重要的价值。
Objective To discuss the ultrasonic characteristics of urachal carcinoma （UC）. Methods The ultrasonographic fea- tures of 32 lesions, including bladder carcinoma （ BC, 18 cases） which were located on the top or anterior wall of the bladder and UC （ 14 cases） were retrospectively analyzed. The difference between the UC and the BC were compared. All of the lesions were confirmed by sur- gery and pathology. Results All of the lesions were appearance as irregular and heterogeneously hypoechoic mass. Of those 32 patients, 14 patients with UC were located at the lower end of urachus and occurred as a solitary lesion without sessile. Among the 14 patients, 8 cases had infiltration of the bladder, 4 cases had calcification and 3 cases had cystic changes. While among the remaining 18 cases with BC,6 cases occurred as multiple lesions with sessile. And there were 5 cases with calcification and 1 cases with cystic changes. Color Doppler signal can be detected in all of the lesions. Three patterns of blood vessels on color Doppler of UC and BC, including central blood vessels pattern（7.14% （1/14）and 72.22% （13/18） for UC and BC ,respectively）, peripheral blood vessels pattern[71.43% （10/ 14） and 11.11% （ 2/18 ） for UC and BC, respectively ] and both central and peripheral blood vessels pattern [ 21.43% （3/14） and 16.67% （3/18）for UC and BC, respectively ] , were found. The pattern of blood vessels on color Doppler has significant difference be- tween UC and BC（χ2 = 15.36,P 〈 0.05）. Conclusion Color Doppler sonography is an important method for diagnosis of bladder tumor. The pattern of blood vessels on color Doppler can help distinguish between UC and BC.
