question: Ive had a kidney abcess in november. It was drained but now apparently I have a cavity in my kidney and there is a connection between the cavity and the rest of the kidney. My doctor wants me to have a surgery to close the cavity. He said that if I were to get another UTI it is possible for my to have another abcess. Is there any way to avoid this surgery?  What would happen if I just waited to get another abcess?
