Blood in the Urine in Men

Blood in the urine can be quite alarming, but keep in mind that it's unusual for men to bleed large amounts through the urine. Even a small drop of blood can turn an entire toilet bowl of water bright red.

However, large blood clots can be dangerous because they can block the flow of urine. They can also cause a fair amount of discomfort as they pass out of the bladder. In general, any blood clot that's bigger than the tip of your little finger would be considered to be large.

Have you passed one or more large clots in the urine?

  Yes, I've passed one or more large clots.

  No, I'm passing only small clots or my urine is just red.
