What does renal hamartoma mean

Renal hamartomas smaller than four centimeters require regular follow-up, do not require special treatment, and grow very slowly. If they are larger than four centimeters, there will be discomfort symptoms, such as back pain, which will affect kidney function, and partial kidney removal can be performed. The CT value is negative, generally between negative thirty and negative fifty, which is its characteristic CT manifestation. Renal hamartoma is called renal angiomyolipoma, a common benign disease, which is composed of vascular smooth muscle and fat in the kidney and is a benign tumor.

What causes left renal hamartoma?

Left renal hamartoma is one of the common benign tumors of the urinary system. The most common cause is hereditary factors. It is a chromosomal dominant inheritance disease. Generally, small hamartomas do not require special treatment, but surgery should be considered if the hamartoma enlarges. The interior of the hamartoma is mainly composed of smooth muscle tissue and adipose tissue. It does not have the characteristics of metastasis. Most hamartomas are benign, so there is no need to panic. It will not metastasize or spread. However, the enlargement of the tumor will compress the surrounding normal renal tissue and cause renal damage. It is still necessary to consider surgical resection.

Minimally invasive surgery for renal hamartoma

For example: CT examination of pulmonary hamartomas shows popcorn-like calcification, renal hamartomas show tuberous sclerosis, hepatic hamartomas are mostly cystic and solid masses, intrahepatic bile duct hamartomas are multiple irregular small cysts, chest wall hamartomas can show bone-like density and mixed calcification foci, and hypothalamic hamartomas can cause symptoms of gelastic epilepsy and precocious puberty. For large hamartomas or those with uncomfortable symptoms, surgical treatment is required. Postoperative pathology confirms the nature of the disease, and the disease rarely becomes cancerous. Hamartomas have complex components, most of which are tumor-like deformities formed by abnormal development of normal tissues, and a few are mesenchymal tumors. The disease is a benign lesion, mainly formed by fat and calcification. For small hamartomas and in the absence of symptoms, surgical treatment is not required.
