Is renal hamartoma a renal cyst? Three differences between renal hamartoma and renal cyst that you should know

There are three main components of renal angiomyolipoma: blood vessels, smooth muscle, and fat. Renal angiomyolipoma, also known as renal angiomyolipoma, is a relatively common benign kidney tumor. Renal cyst is a cystic mass-like nephritis. Generally speaking, renal hamartomas appear as high echoes on color Doppler ultrasound, and renal cysts often appear as anechoic or hypoechoic on color. Renal hamartomas appear as high-density shadows on CT, and renal cysts appear as low-density shadows on CT.

Before understanding the difference between renal hamartoma and renal cyst, we need to have a separate understanding of these two diseases. Renal hamartoma is also known as renal angiomyolipoma. As the name suggests, it is a renal tumor composed of three parts: blood vessels, smooth muscle and fat. It is a common benign kidney tumor. Renal cyst is a benign tumor on the kidney, which usually does not affect the normal physiological function of the kidney. Large renal cysts close to some key parts may cause hydronephrosis, which is generally not felt by the human body.

1. The causes are different. Renal hamartoma is a benign tumor that occurs in the kidney. At present, the cause is not very clear. Most experts believe that this is a developmental abnormality in the kidney area, which may be related to genetic factors. The cause of renal cysts is mainly due to infection and diet. Common infection factors include upper respiratory tract infection, urinary tract infection, skin infection, gastrointestinal infection, trauma infection, instrument infection, etc. If this disease is found, regular reexamination is required. Small cysts do not require treatment. However, if it exceeds a certain value, surgical removal is required.

2. The symptoms are different. Renal hamartoma can cause discomfort or pain in the waist and abdomen, and there will be hematuria, urine protein and blood pressure changes, and abnormal renal function. Hamartoma has the characteristics of high incidence, high canceration rate, high recurrence rate, high surgical difficulty, and many complications. At present, there is no effective treatment method at home and abroad, which leads to many hamartoma patients growing too fast, rupturing and bleeding, organ damage, and tissue necrosis. Renal cysts below 5.6 cm are asymptomatic. If the cyst has reached seven or eight centimeters, it may cause discomfort in the waist. However, if multiple cysts are large and cause obvious compression on the renal parenchyma, it will damage renal function. If there is bleeding or infection in the cyst, it will cause acute low back pain and fever.

3. Treatment methods are different. There are many methods for treating renal hamartoma. Renal hamartomas smaller than 4 cm do not require special systemic treatment and require regular hospital check-ups. Treatments for severe renal hamartomas include embolization, nephron-sparing surgery, nephrectomy, renal transplantation, or hemodialysis. Most renal cysts are treated with minimally invasive methods such as laparoscopy to remove the top of the cyst, which is actually a decompression method to drain the fluid in the cyst.

These are two different diseases. Renal hamartoma is a solid space-occupying lesion and an autosomal dominant genetic disease. Renal angiomyolipoma, also known as renal angiomyolipoma, is a type of lipoma. Renal cysts are cystic masses of varying sizes in the kidney that have nothing to do with the outside world. Renal cysts and hamartomas are benign tumors.
