Patients with membranous nephropathy can undergo coronary artery bypass grafting surgery when their renal function is less damaged and their condition is stabilized; for patients with more serious renal function damage or even uremia, the surgery can be performed under the condition of dialysis. Membranous nephropathy is a common kidney disease, which mainly leads to kidney function injury. Depending on the degree of kidney injury, patients have different ability to tolerate surgery. For patients with less severe kidney injury and better physical condition, coronary artery bypass grafting surgery is generally tolerated, so the surgery can be performed. For patients with more severe renal impairment or even uremia stage, if the other organs of the body are still functioning well, the surgery can be performed under dialysis condition, but there is a certain risk. If patients with membranous nephropathy need bypass surgery, it is recommended to consult a regular hospital in time, and decide whether to perform the relevant surgical treatment after a comprehensive assessment of the condition by a physician.
