Infected stones, which are alkaline stones, tend to form in alkaline urine. Therefore, infected stones should acidify the urine, take a lot of vitamin C or potassium citrate orally, eat more fresh vegetables and fruits, and eat more oranges, so as to effectively prevent the infected stones from continuing to grow. Control the infection as soon as possible, through the urine culture to clarify the type of microorganisms, as well as the sensitivity of the drug, choose sensitive antibiotics, and continue to use for about two weeks, so that the inflammation will be basically controlled. Have surgery as soon as possible to remove the stone as soon as possible. When you have surgery, make sure you do your best to remove all the stones. Otherwise the remaining stones will quickly grow back again to form staghorn-shaped stones, and infected stones grow very quickly.
