Expanding the possibilities of ultrasonography in gynecology

We used a Taschiba SAL-50a ultrasonograph operating in real time with a 5 MHz linear transducer to study pelvic anatomical structures. For sufficient visualization of internal genital organs we recommend women under investigation not to urinate for 5-7 h or to drink 2-4 glasses of liquid (lemonade, juice, water) in combination with diuretics (furosemide, etc.) two hours before the examination. In urgent cases, fill the bladder by catheterization with Nelaton, Pousson, Guillon instruments until the bladder completely overlaps the uterine floor and is as large as possible to the level of the terminal line from the pelvic bone ring. In order to clearly visualize the cervix, we also suggest introducing a wooden (similar to the electrode used in vaginal electrophoresis) or lead-embonite rod in the vagina, which are quite clearly seen when using hypersonic frequencies with a wave length above 10⁹ Hz, or we recommend a similarly shaped lead rod with a wave attenuation coefficient greater than 8.01 cm. Sharply differentiated on the display from the normal tissue, they provide information about the structure of the cervix in the area of the external pharynx.
