Renal blood volume insufficiency may be classified into two cases: renal blood volume insufficiency due to insufficient circulating blood volume, which requires rehydration therapy, etc., and that due to localized causes such as renal artery stenosis, vascular malformation, etc., which can be relieved by medication and interventional therapy. 1. Reduction of effective circulating blood volume due to diarrhea, vomiting, blood loss, heart failure, resulting in insufficient renal blood perfusion, at this time, it is necessary to replenish body fluids or even blood transfusion to replenish blood volume. 2. Renal artery stenosis, arteriosclerosis, vascular malformation will also make the kidney blood volume insufficient. For renal artery stenosis, and the condition is relatively mild, under the guidance of the doctor can be used under the guidance of prostaglandin injection and other vasodilating drugs, to improve renal blood flow, to alleviate the lack of renal blood volume. For patients caused by renal artery stenosis and vascular malformation and in more serious conditions, endovascular intervention and surgery can be used. In case of renal blood volume insufficiency, it is necessary to find out the cause of the disease in time and choose the appropriate treatment plan under the guidance of professional physicians.
