Hi Thank you for asking HCM. I have gone through your query. Your dad s problem is most likely urinary infection. It can be due to accumulation of post voidal urine because of enlarged prostate. You should get a urine routine examination and culture to rule out that. In such case i advise empirical antibiotic therapy like norfloxacin initially and change antibiotic after culture report if necessary. Prostate enlargement should be assessed by ultrasound and can be managed by drugs like tamusulosin and dutasteride. Hope this may help you. Let me know if you have any further queries.
