Blood 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. If you are passing different-shaped clots in your stream, they could represent bleeding from the urethra or prostate (in men). Clots can be wormlike, and if associated with pain it could represent clots coming from your ureters(tubes from your kidneys to your bladder).
Since it was only one episode, nothing is to be done as the tests are clear. If the repeat happens, then diagnostic tests that may be performed include Urinalysis, Urine culture, X-rays of the kidneys, Cystoscopy, IVP, Abdominal ultrasound and CT scan of the abdomen.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Okay so after my last episode, I passed 1 or 2 clots throughout the next few days and then did not experience any problems for the next ten days. My girlfriend was just over tonight and she was sitting on top of me for awhile and when I went to the bathroom I was pissing blood again. There was no pain associated with this, but Im starting to get annoyed by the problem. Any thoughts?
