What are the examination measures for renal hamartoma

What are the inspection measures for renal hamartoma? Each disease has corresponding inspection measures to reduce misdiagnosis and mistreatment, so it can be seen that inspection is very important. If you suffer from a serious disease such as hamartoma, you must do an inspection in time. So what are the inspection measures for renal hamartoma?

What tests should be done for renal hamartoma?

Because the tumor is close to the collecting system, rupture may cause hematuria and occult blood in urine examination. Bilateral renal hamartomas may cause hypertension, renal insufficiency, and abnormalities in blood creatinine and urea nitrogen.

1. Ultrasound is quite characteristic. The fat and blood vessels in the tumor show evenly distributed dense high-echo areas, while the muscle and bleeding parts show low-echo areas.

2. X-ray abdominal films showed unclear renal contours, disappearance of the psoas major muscle shadow, and calcification in the renal area. Urinary tract angiography showed that the mass compressed the renal pelvis and calyces, causing them to deform, lengthen, shorten, etc., but without erosion.

3. CT is the main method for diagnosing renal hamartoma, which presents as a mass of uneven density, contains a lot of fat, and has a CT value of -40 to -90 Hu.

What causes renal hamartoma?

The cause is still unclear. Renal hamartoma is divided into two types: ① Those with tuberous sclerosis: no symptoms, bilateral, small tumors, multiple lesions, and young age of onset; ② Those without tuberous sclerosis: often have subjective symptoms, multiple or solitary, unilateral, larger tumors, and older age of onset. The above classification was in the 1960s. With the advancement of imaging, especially the popularization of ultrasound examinations, people without tuberous sclerosis may also be found to have bilateral kidneys, multiple lesions, small lesions, and no clinical symptoms. Currently, renal hamartomas seen in clinical practice are often discovered accidentally during physical examinations, and the symptoms are not obvious.
