This a medical emergency. If you have not been treated you should be. Patients with high INRs (INR > 8) are at significant risk of major hemorrhage. For those with bleeding symptoms (if you have them--blood in urine, gums nose) urgent reversal is required.

I saw a doctor today for blood in urine however he said I had a UTI but I have been on coumiden since October 2007 for DVT. In January I was in Hospital and doctor said keep taking two pills each day (7.5 mg x2) and PT/INR was 3 .0 then.

I am sorry but I guess I dont understand. When was the INR of 8?
And if the INR was not checked at least monthly it should have, perhaps even more frequently. the INR of 2.5 to 3 would be acceptable. higher INRs have a greater risk for bleeding.
So to summarize---keep the INR around 2.5-3.
The INR of 8 is a medical emergency.
You can, or course , still have a UTI while on coumadin, but i would get that rechecked after the UTI is successfully treated.
