in the urine should never be ignored. This could be the first sign
of a serious condition.
in the urine can present in one of two ways: gross hematuria (blood
that you can see in the urine), and microscopic hematuria (blood that
is only seen when the urine is examined under a microscope). Both
types can have serious causes.
the blood in the urine is at the beginning of urination, it most likely
comes from the urethra, (the tube from the bladder to the outside).
Blood throughout urination is most likely from the bladder or kidneys
or ureters (the tubes connecting the kidneys and the bladder). Blood
at the end of your stream may be from the bladder or prostate (in
of blood in the urine vary, from inflammatory conditions to cancers.
Urinary tract infections and kidney, bladder, or ureter stones are
also frequent causes. Cancer of the urethra, bladder or kidneys also
may also show up as blood in the urine.
in the urine in anyone over the age of 40, especially in people who
smoke, should warrant full urologic evaluation because the most common
cause of blood in the urine in this group of people is bladder cancer.
