What to do if there is a hamartoma on the kidney

How to treat renal hamartoma? Renal hamartoma, also known as renal angiomyolipoma, is a benign tumor. The incidence has been increasing in recent years, which may be related to the improvement of diagnostic technology. The clinical features are multiple lesions in both kidneys, combined with mental retardation, butterfly-shaped sebaceous adenoma on the face, etc. It is more common in women, and the age of onset is mostly 20-50 years old. So do you know how to treat renal hamartoma? Let's take a look at it together.

How is renal hamartoma treated?

1. Treatment principles

The treatment of renal hamartoma is mainly based on symptoms, tumor size, etc.

1. For asymptomatic tumors with a diameter of less than 4 cm, since the risk of spontaneous rupture is low, close observation and active monitoring of tumor size progression can be performed;

2. For hamartomas with a diameter of more than 4 cm, if the tumor is progressively enlarged or if the tumor is suspected to have a malignant tendency, surgical resection is recommended;

3. If the tumor is large and ruptures and bleeds, interventional embolization should be considered first, and then re-evaluated after the condition stabilizes, and a decision on surgical treatment should be made based on the situation.

2. Treatment

Regardless of the treatment method adopted, preserving renal function should be the top priority.

1. Interventional embolization: Generally speaking, interventional embolization is simple and safe, but some scholars believe that this treatment is not thorough and cannot guarantee complete blockage of the blood supply to the hamartoma, so there is a possibility of secondary embolization or conversion to surgical treatment. However, it is a good first aid method for ruptured bleeding.

2. Surgical treatment: The surgical procedure of preserving renal tissue, which we call partial nephrectomy, can not only completely remove the tumor, but also preserve renal tissue and protect renal function to the greatest extent. It has very good long-term effects and is very meaningful for the treatment of renal hamartoma (including cases of partial rupture and bleeding).
