[/INST] Hello Friend . Thanks for your query to Chat Doctor . I read your concern about kidney stone and there is nothing to be worried as Small Kidney stone will not damage your kidney permanently, moreover it does not have issues with sexual life, Kidney stones once detected it will be cured, but chances of recurrence is more as stones tries to develop if not on Diet and medications. I suggest you to continue same medications as prescribed by your Doctor for another 3 to 6 months and Chat Doctor. Hope this information is helpful. Thanks & Take Care </s>
