My father is 85. He woke up this morning to blood clots in his urine. The urine is very red with multiple clots. He had prostate surgery about 7 years ago. He has had no problems up until now. He has no pain or fever or any other symptoms. we went to our family doctor this morning who said to go to the urologist. We can t get in to the urologist until Monday. Is is alright to wait or do we go to the ER?
