Background. In recent years the indications for retroperitoneal surgeries using retroperitoneal access under conditions of retropneumoperitoneum (RPP) have significantly expanded, therefore, the study of organism reactions to this phenomenon is relevant. Purpose: To study the dynamics of microcirculation during retroperitoneal surgeries in conditions of retropneumoperitoneum. Material and methods: The dynamics of microcirculation in 128 patients operated on renal cysts under different modes of RPP was studied. We measured 11 parameters of microcirculation using LAKK-02 device (LDF) (NPP "Lazma", Russia). Results: it was found that the most important factor affecting the microcirculation parameters is the increased pressure mode in retroperitoneal space. In the group with the most tense RPP (over 12 mm Hg) and longer operation there were systemic changes of microcirculation, as well as 4-5 times increased frequency of lower limbs edema in the postoperative period on the 2nd day. Conclusion. All microcirculation changes are probably connected with the activation of compensation mechanisms in response to the obstruction of the main venous blood flow.
