Краткое описание

Modern medical cryoequipment application methods (for example, for the third generation of cryosurgical systems) are not capable of providing sufficiently accurate cryoexposure dosing to complex target regions. The same problem applies to the methods providing therapeutic, hypothermic, and cryopreservation effects. To improve the assurance of the dosing quality it is necessary to have a sufficient quantity of experimental data on actual particular cases of cryoexposure. One such case that of the simultaneous application of a heater and a cryoprobe. During prostate cryoablation a warming catheter is used to prevent damage to the urethra. To obtain up-to-date experimental data, two physical experiments at different initial temperatures of the tissue phantom were carried out (at 24°C and 37°C). The minimum temperatures near the cryoprobe, the shape and dimensions of the freezing zone, and the temperature on the surface of the warming catheter were defined. The influence of taking into account the initial temperature of the target region was shown. The results of this study may be used when designing cryoprobe placement near urethral warming.
