Why is that before i urine a stringy blood comes out followed by urine ? please someone help!

Doctor can evaluate: There are many causes for blood in the urine, such as infection, kidney stones, or autoimmune disease. Blood in the urine should always be evaluated by a physician. The problem could be in the urethra (connecting the bladder to the outside of the body), the bladder itself, the ureters (connecting the kidneys to the bladder), and/or the kidneys.

Concerning!: Don't know your sex or age but in either situation, if you are passing blood per your urethra and then pass urine, you have a problem that needs evaluation. One could have an infections, a tumor (malignant or benign), or some other inflammatory process in the urinary tract. It must be established as to cause. Please see your pcp or a urologist and get examined and some testing. Very important!
