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.

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.
