HelloThanks for your query, based on the facts that you have posted it appears that your husband has undergone Ureteroscopy and D. J stenting for removal of ureteric stone and since then has fever which is not responding to antibiotics. This is what is called as Urosepsis and known to occur in few patients after getting treated for ureteric stone. Since his urine culture is negative for bacteria, and he has been on Meropenum for almost one month you may opt to change the antibiotics to simple like Ciprofloxacin and Nitrofurantoin for 2 more weeks. Ensure he Chat Doctor. Hope this will get resolved soon.
