If something grows on the kidney, attention should be paid to avoid kidney cysts, kidney tumors and other diseases. It is best to go to the hospital as soon as possible to have a B-ultrasound examination or renal function examination to clarify the specific cause, and then carry out symptomatic treatment. If it is caused by disease, symptomatic treatment should be carried out as soon as possible according to the condition, so as to avoid serious harm to the kidney. At the same time, during the treatment, we should pay attention to relax, not be overly nervous, pay more attention to rest, avoid overwork, and get enough sleep. Then we should also pay attention to regularly go to the hospital for recheck, and observe the recovery of the disease at any time.
