Clinical Analysis of the Antihypertensive Effect of Laparoscopic Peripheral Nerve Blockade of the Renal Artery in Patients With Retroperitoneal Disease and Hypertension

"1. When only the main renal artery is present: The complete dissection of the renal artery should be performed in the distal 2/3 portion, close to the renal hilum. The connective tissue and nerve tissue within a 1 cm radius from the center of the renal artery lumen must be completely separated (using instruments such as an ultrasonic scalpel or monopolar hook, etc.). The length of the dissected renal artery should be at least 0.5 cm, forming a dissection ring.~2. When accessory renal arteries are present: In addition to the main renal artery meeting the aforementioned standards, the accessory renal arteries must also be dissected. The radius of the dissection ring should be 0.7 cm, with a length ranging from 0.3 to 0.5 cm.~3. When renal polar arteries are present: Dissection may be performed appropriately based on the surgical conditions.~4. The prerequisite is to ensure the safety of the surgery, specifically the safe resection of the primary lesion."

The surgeries related to the primary disease include laparoscopic partial nephrectomy, laparoscopic adrenalectomy, and other similar procedures.
