⑤ Kidney B ultrasound examination, the kidney shrinks or the two kidney size is different, the surface presents the granular shape to be uneven;
⑥ exclude cases of primary kidney disease associated with hypertension;
⑦ Renal biopsy showed that renal arteriosclerosis was the main pathological change.
