[Ultrasonic examination and lymphography in the diagnosis of metastases of rectal cancer].

The diagnostic effectiveness of ultrasound and lymphographic investigations was assessed in 89 rectal cancer patients. Lymphography was shown to be a more informative method as it permitted the detection of metastases in 6 patients in whom USI results were negative, metastatic involvement in 2 patients, specifying the type of pathological changes of the enlarged lymph nodes in 14 patients. In a normal lymphographic picture metastatic involvement was detected in 37 cases using echography.

[Diagnosis of tumors of the bladder and rectum by the method of high-resolution transvaginal echography].

Analysis of the results of high resolution transvaginal US-tomography in 32 women with malignant bladder and rectal tumors made it possible to assess the potentialities of this new method for the diagnosis of a degree of local spreading of these tumors. As compared to transabdominal echography UST proved to be more informative in tumors of the cervix, basis and anterior wall of the bladder and in calcifications on the tumor surface which were detected in 3 patients. Transvaginal US-tomography with a contrast study of the rectal walls provided good diagnostic information on a degree of local spreading of malignant rectal tumors.

[Transrectal and transvaginal echography in cancer of the rectum].

To assess the diagnostic value of ultrasonography in rectal carcinoma, the procedure was performed in 48 such cases. Stage was reliably established in the majority (95.8%) of patients.
