Have Urology Questions? Ask a Urologist Online.
There are a couple issues that I see here. The first is the blood in the urine. For that, you will need to see a urologist to do a special CT scan with IV contrast to evaluate the entire urinary track for the source of the bleeding. Possible causes include the infection, kidney stones, or even cancer of the urinary tract. You will then need cystoscopy to look inside the urinary tract to see where the bleeding is coming from.
As for the resistant urinary tract infection, if your urologist cannot determine an appropriate or antibiotic to treat this, and you may need to be admitted to the hospital where an infectious disease doctor may need to review your urine cultures to determine the appropriate antibiotics to treat the infection completely. Hope this helps and let me know if you have questions.
