Renal stenting generally refers to stenting of renal artery stenosis, and the surgical procedure involves heparinization, abdominal aortography, and intervention. 1. Heparinization: it is a hormone, small molecule chemical that can be found in the kidney, often injected before performing surgery, such as cardiac vascular surgery, kidney surgery, cerebral vascular surgery, which can play the role of anticoagulation. 2. Abdominal aortography: mainly utilizing imaging to observe, the current situation of the renal artery is clear, the site, degree and extent of renal artery stenosis, in order to carry out the next step of stent implantation treatment. 3. Interventional therapy: Usually the femoral artery approach is used, and if necessary, the upper limb artery approach can be chosen to place the stent in. Before renal stent surgery, it is often necessary to do routine physical examination, follow the doctor’s instructions for preoperative preparation, and follow the doctor’s instructions for postoperative recovery, in order to strive for early recovery.
