Pathophysiology Of The Cortico-sympathoadrenal System In The Postoperative Period Of Partial Nephrectomy
Introduction. Organ-preserving kidney surgeries are widespread in urological practice. Any surgical intervention triggers a cascade of reactions in the body that are characteristic of stressful situations, which adversely affects blood flow volume in the parenchymal organs, worsens microcirculation, and reduces the trophic and reparative abilities of organs. The application of anti-ischemic protection is an essential part of patient rehabilitation to maintain renal function. Objective. To investigate the nephroprotective properties of α-tocopherol acetate (a-TA) and its effect on α-tocopherol acetate (a-TA) parameters of the cortico-sympathoadrenal system following organ-preserving kidney surgery. Material and methods. An experimental study was performed on 70 white laboratory rats, 10 of which were not subjected to surgical treatment. Sixty rats underwent lower pole left kidney superimposition with Z-joints. Postoperatively, 30 rats were intramuscularly injected with a 10% oil solution of 0.2 mL a-TA twice a day for 5 days. The cortico-sympathoadrenal system parameters were determined on the 7th, 14th, and 28th days. Results. Postoperative administration of a-TA resulted in early normalization of the cortico-sympathoadrenal system. Conclusion. The studied indices regarding the tissue of the operated kidney are responsible for regulating vascular tone, severity of the inflammatory response, microcirculation, and reparative processes. The use of a-TA accelerates recovery from organ-preserving surgery and biochemical abnormalities. (For citation: Shormanov IS, Los MS.
