经阴道彩超在宫颈癌诊断中的价值

目的探讨宫颈癌的声像图特征对临床诊治的价值。方法应用彩超仪经腹壁及阴道或直肠探查分析宫颈癌的声像图及其血流情况。结果53例宫颈癌中，低回声33例，其中均匀细点状回声25例，不均质回声8例；高回声13例；等回声5例；2例超声未能检出。宫腔内有积液回声14例。应用彩超仪经腹壁检查可测及血流信号31例，未测及明显血流信号20例。对部分经阴道或直肠探查发现原先经腹壁可测及血流者，血流信号更加丰富；对血流信号不明显者，则绝大多数能测到血流信号。RI测值0．36～0．87，平均0．59。结论超声可发现Ⅱ～Ⅲ期宫颈癌，原位癌及Ia期超声难以发现。对于肿瘤内浸、淋巴转移、累及输尿管或肿瘤压迫导致肾及输尿管积水情况可提供有价值的诊治依据。

Value of Transvaginal Ultrasound in Diagnosis of Cervical Carcinoma

Objective To evaluate the sonographic features of cervical cancer on the value of clinical diagnosis and treatment. Methods Color doppler instrument by abdominal and vaginal or rectal exploration of cervical cancer uhrasonography and blood flow situation. Results In hypoechoic 33 cases,uniformly fine point echo 25 cases,heterogeneous echo 8 cases; high echo 13 cases,equal echo 5 cases,2 cases of uhrasound failure detection. Intrauterine with effusion echo 14 cases. Application of the abdominal wall color doppler uhrasound examination for the detection of blood flow and signal 31 cases,no significant blood flow signal 20 cases. On some of the vagina or rectum original exploration through the abdominal wall can be found and measured blood flow, blood flow signals richer, and the signal flow was not obvious to the vast majority of blood flow can be measured signal. RI measured values：0.36 to 0.87,average 0.59. Conclusion Ultrasound can be found phase Ⅱ to Ⅲ cervical cancer, carcinoma in situ and is difficult to find for period of ultrasound. The baptist tumor,lymph node metastasis, or tumor involvement ureteral compression caused renal and ureteral water situation can provide valuable basis.
