Russia has come up with a painless cancer cryotherapy technique

The staff of Sechenov University began to apply improved technology for combating kidney tumors through negative temperatures.

The program has already been registered and can be used in medical institutions.

Doctors used computed tomography to more accurately inject cooling cryopigles into the affected area of the organ, after which they gradually lowered the temperature using electricity. The proposed technique made it possible to reduce injury and perform the procedure under local anesthesia. Therefore, this type of therapy can be prescribed to patients who do not have other treatment options available. And after cryotherapy, the patient can be released home after a few hours, although previously this could only be done after a long time.

"Previously, ultrasound was used for guidance, but we began to use computed tomography for this, which made it possible to increase the accuracy of the procedure. CT scans are used to insert special cryopigles into the tumor. CT allows you to clearly see the boundaries of the tumor and track the formation of an ice ball around it when the needle begins to conduct cold. If an ice ball covers the entire tumor according to CT scans, it means that all oncological canons were observed during the procedure," said Stanislav Ali, associate professor at the Institute of Urology and Human Reproductive Health at Sechenov University.

During cryoablation, the diseased cells are exposed to extreme cold. Experiments have confirmed that tumor tissues die at -40 degrees Celsius. The updated cryoablation procedure was successfully performed on a 69-year-old patient with serious concomitant diseases.
