How big does a kidney cyst need to be for surgery?

Patient's question:

How big in cm does a kidney cyst need to be to require surgery? I checked my test results carefully and it was 1.2. Do I need surgery?

Doctor's answer:

Generally, it is believed that if a kidney cyst exceeds 4 centimeters, surgery is recommended. Currently, the cyst is not large, so surgery is not needed for now. It is sufficient to have a follow-up examination every year. Based on the specific situation, if lower back pain or discomfort in the waist reappears, it could be possible that it is muscle strain in the lower back. In such cases, it would be helpful to have a massage and physical therapy to alleviate the condition.
