EXPERIMENTAL RATIONALE FOR HEMOSTATIC SUTURES DURING RESECTION OF THE KIDNEY FOR ITS TUMOR

The investigation deals with the study of the biomechanical properties of renal tissues and the comparison of different hemostatic suture procedures used during resection of the kidney for its tumor. The performed experimental study allows one to recommend that a renal capsule as the organ’s most stable and plastic part must be necessarily inserted into the hemostatic suture on both sides. The elastic modulus (Young’s modulus) serves as an integral indicator of the deformation-strength properties of renal tissues, which enables it to be recommended for the wider use in experimental and clinical studies. The proposed modified suture can minimize the number of postoperative bleedings from the renal parenchyma and reduce the time of surgery, thereby improving the results of organ-saving treatment in patients with kidney cancer.
