<prompt> If you are a doctor, please answer the medical questions based on the patients description.10 days ago, my husband just removed a stent from a kidney stone. The last 2 nights he has had a low grade fever around 7pm and then in the middle night he gets night sweats. He wakes up and feels great, no other symptons. So what is causing the fever?  <response>: His understand your concern. From the history provided it is likely your husband has developed a urinary tract infection following stent removal which is a known complication of the procedure. Please provide a sample of urine for culture at your doctors office and start on antibiotics as trimethoprim or co-amoxyclauv until the results are back. You could take paracetamol 1gm four times daily, Chat Doctor.
