METHOD FOR ANTISCHEMIC PROTECTION OF LEFT KIDNEY PARENCHYMA DURING LAPAROSCOPIC RESECTION Russian patent published in 2022 - IPC A61B17/00 A61B17/12 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to urology and oncology. Access to the left kidney, mobilization of the renal artery, vein and gonadal vein, catheterization of the renal artery and isolated perfusion of the left kidney with a chilled solution are performed. In this case, vascular clamps are applied to the renal artery and vein. Excluded from the main circulation. The anterior wall of the renal artery is dissected, the renal artery is catheterized with a peripheral balloon catheter. They cross the left gonadal vein, which flows into the left renal vein, and start washing the left kidney with Ringer's solution cooled to +4°С. Then the left kidney is resected within healthy tissues. The kidney wound is sutured, the area where the left gonadal vein flows into the left renal vein is treated with bipolar coagulation, the clamp is removed from the left renal vein, the balloon catheter is removed from the left renal artery, the defect is sutured with a U-shaped atraumatic suture. The vascular clamp is removed from the renal artery.

EFFECT: method provides the possibility of long-term intracorporeal shutdown, which reduces the risk of complications associated with prolonged warm ischemia, as well as volemic, metabolic and hypothermic complications that develop during cold ischemia by other methods, and also reduces the risk of damage to the left renal vein, which is not cannulated.
