How is nephrosis caused?

The cause of renal angiomyolipoma is not particularly clear. It may be related to inactivation and mutation of x chromosome and loss of gene heterozygosity, resulting in abnormal proliferation of normal tissues. Renal angiomyolipoma is a benign renal tumor, mainly composed of adipose tissue smooth muscle and abnormal blood vessels. It can persist and increase, and may even compress the kidney and surrounding tissues and organs. If the renal angiomyolipoma is smaller than 4 cm, it can not be treated. It can be reviewed every six months. However, when large hamartomas cause renal failure or rupture and massive bleeding, it is necessary to remove the kidney as soon as possible. Most renal hamartomas are discovered accidentally during physical examination or disease examination. After discovery, doctors should cooperate with doctors for further diagnosis and treatment as soon as possible.
