Kidney cysts are mainly treated with regular observation and surgery, and drugs can be used for anti-infection treatment when cysts are combined with infection. 1. Surgical treatment: for asymptomatic renal cysts, no special treatment can be done, and regular rechecking can be done. If the diameter of the cyst is more than 4cm, or if it produces compression symptoms on the surrounding tissues, cyst aspiration is feasible. Larger renal cysts (more than 10 centimeters in diameter) or more serious conditions can be treated with nephrocystectomy. 2. medication: when renal cysts are combined with infections, penicillin, cefuroxime, cefazoxime and other drugs can be used for treatment under the guidance of the doctor. Patients diagnosed with renal cysts are advised to go to regular hospitals in time for standardized treatment under the guidance of doctors, and not to use drugs on their own.
