Route of administration of contrast media into the uterus

 

(57) Abstract:

The invention relates to medicine and can be used for injection of contrast media into the uterus. Conduct x-ray examination, in which the uterine cavity is placed a double elastic spray conduit, through which when applying the radiopaque substance is filling the first container in the form of a balloon and the second balloon, which hugs and contrasts the surface of the tumor. The method improves the accuracy of intraoral diagnosis of malignant processes of the body of the uterus and prevent tumour metastasis, as well as the penetration of other pathological cells through the vessels and the natural passages in other parts of the uterus.

The invention relates to medicine, namely to x-ray research in Oncology, and can be used in gynecology when performing fluoroscopy hollow organs in the presence of a pathologic focus.

It is known that intracavitary diagnostics of malignancies of the body of the uterus is associated with serious technical difficulties and hazards (Rusin J. I. Contrast radiography in gynecology. - M.: Medgiz, 1959, S. 60-70). Actually the target into the cavity of the pipe and further into the abdominal cavity, but accordingly accompanied by the spread in the same direction tumor cells from the primary lesion.

When all these costs are almost impossible to determine the amount of the residual cavity of the uterus, as well as the size and shape of the tumor. It should be noted that changing the volume of the uterine cavity in the direction of decreasing indirectly confirms the progression of the process, and the increase - about the effectiveness of any treatment method.

Known "Method of filling hollow bodies athenacentral substance" (ed. mon. 1009474, from 07.04.83. Bull. 13, ed. Y. S. Sidorenko, A. K. Pankow, F. M. Stein), involving the introduction of a radiopaque substance into the test cavity is chosen as a prototype. The essence of the method is that for the purpose of preventing the dissemination of the contents of the nidus, prior to the introduction of a radiopaque substance into the hollow body is placed an elastic bag which is injected radio-opaque substance to fill the entire cavity of the hollow body of elastic bag.

Thus, the use of this method allows to avoid the contrast medium in the pipe, and with him and tumor cells. In addition to the government, that it is impossible to define the contours of tumors of the uterine cavity. In fact, during the filling of the flexible bag he always tends to take the form of a sphere, so its surface he can only compress the tumor, but does not fit her, passing her contours.

The aim of the invention is the determination of the contours and volume of tumors of body of uterus during the initial radiological investigation and treatment stages.

This goal is achieved by the fact that when conducting x-ray examinations of the uterine cavity prior to the introduction of contrast medium into the uterine cavity placed double elastic spray conduit, through the conduit injected radiopaque substance, fill the first container in the form of a sphere, then the second canister that fits and contrasts the surface of the tumor.

The invention "Method of injection of contrast media into the uterus" is new, because it is unknown the level of medicine in the field of introduction of contrast agents in x-ray hollow organs in the presence of a pathologic focus.

The novelty of the invention lies in the fact that prior to the introduction of contrast medium into the uterine cavity placed double elastic BA is the first canister, who hugs and contrasts the surface of the tumor.

The invention involves an inventive step, as a physician-oncologist, radiologist, it is unknown under fluoroscopy hollow organs in gynecology in the presence of a pathologic focus.

Known methods of radiological examination of the uterus accompanied by ingestion of contrast material into the cavity of the pipe and then into the abdominal cavity, the spread of tumor cells from the primary lesion. It is almost impossible to determine the residual volume of the uterine cavity, are not covered by the tumor, the change of volume during treatment.

Thus, the proposed technical solution is not obvious, has distinctive characteristics, is not clear from the level of development of Oncology in the field of x-ray examinations in Oncology, it is not known neither in the world nor in the Russian and CIS medical literature.

The invention is industrially applicable as it can be used in health care for radiological research in Oncology, gynecology, cancer research institutes, oncologic dispensaries and protracted funds in the uterus" is as follows.

In a hollow organ such as the uterus, enter the device is a hollow rigid conductor, rounded on the end inserted into the uterus, and is equipped with side holes for expiration in the uterus of contrast agents. On the rounded end of the conductor is wearing a double elastic balloon, the neck of the balloon is fixed to the conductor below the holes. The device is introduced into the body before contact of the conductor with the fundus of the uterus. Then double elastic balloon serves a radiopaque substance. When filling the first balloon inflated balloon fills the free space of the uterine cavity. When completing the second spray it adheres to the surface of the tumor. After that produce x-rays. On radiographs easily detect filling defects in the presence of a tumor in the body of the uterus. Tumor of the uterus fits the second elastic balloon, contrasts the contours of the surface of the tumor on the x-ray.

Technical and economic efficiency "as a way of introduction of contrast media into the uterus" is that the application of the method allows abdominal x-ray examination provides an objective and accurate vnutripolostno the residual cavity of the uterus decrease in the progression of the process, while increasing the effectiveness of treatment. Furthermore, the method prevents tumour metastasis or infiltration of other abnormal cells through the vessels and the natural passages in other parts of the uterus.

Route of administration of contrast media into the uterus, including rentgenologicheski study, characterized in that the uterine cavity is placed a double elastic spray conduit, through which, when applying a radiopaque substance, is the filling of the first container in the form of a balloon and the second balloon, which hugs and contrasts the surface of the tumor.
