Blood in urine (hematuria) from UTI, why?

Koyaanisqatsi-RN · Apr 15, 2009

From what I recall from Micro....

Some bacterial actually bind to mucous membranes, and when they are washed out of the urinary tract by urine, they actually tear off from the membrane, separating tissue which causes a trace amount of blood.

That could be entirely wrong, but I'm relatively sure I recall that being the main reason for blood in the urine from a UTI.

Well I know what I wrote is true, I'm just not sure if it's the answer your instructor is looking for. Keep in mind too that there is different types of bleeding in urine. If it's constant stream of pink then the blood may be coming from the kidneys or ureters. If just a little blood at first it's more likely in the urethra.

You should go to this link from the NIH, it list why and how a person gets hematuria.

the reason there are rbcs in urine when there is a uti lies in the fact that the inflammatory response is taking place. first, know what a uti is. uti is infection anywhere in the urinary system (kidney, ureters, bladder, urethra). the inflammatory response occurs along with all infections. mast cells at the site of infection rupture and release histamine which causes the blood vessels in the surrounding area to dilate and increases their permeability. this results in the escape of some rbcs and wbcs into the urine, particularly when the infection has affected the ureters, bladder, and/or urethra. the result of the actions of histamine are the cardinal signs of inflammation: redness, heat, swelling and pain. hematuria is a secondary effect because of the blood vessel dilation and permeability.

urosepsis: because of the vascular permeability, bacteria that have invaded the bladder mucosa are able to escape into the blood stream and this is the actual start of septicemia. once the bacteria enters the bloodstream they release endotoxins and the symptoms of bacteremia are produced.
