For renal cysts, most cases are treated conservatively. Only when the cyst volume of the patient exceeds 5cm, local minimally invasive puncture treatment is considered. The size of the cyst can be seen by examining the kidney color ultrasound. For most patients, the size of cysts is relatively small, and most of them are about 2cm in diameter. This kind of small cyst has no impact on the human body, and the growth of the cyst is very slow, so it is possible to carry this cyst for life, but it will not affect the human body. In life, pay attention not to stay up late and overwork. In diet, pay attention not to drink alcohol, not to drink strong tea, coffee, and not to eat barbecue food to avoid stimulating the enlargement of cysts. Recheck the kidney color ultrasound once a year to understand the size change of the cyst. At ordinary times, we should pay attention to regular follow-up visits to the hospital.
