Blood, No Infection in Urine

[natethegreat80]

I am a 29 year old male, no personal history of cancer or urinary problems.  My father, paternal uncle, and paternal grandfather had prostate cancer.
  
My symptoms are:
- Mild lower back pain
- Burning sensation while urinating (especially at peak flow)
- Blood is noticed at the end of my urination (pink not red in color)

I had a urine analysis and it showed blood in my urine, but no infection.  I also had a CT scan and it reported thickening of the bladder walls.  I'm waiting to see a urologist.
What could this be?

Hello,
If you are passing different-shaped clots in your stream, they could represent bleeding from the urethra or prostate. Clots can be wormlike, and if associated with pain it could represent clots coming from your ureters(tubes from your kidneys to your bladder). When 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). 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.

The treatment will depend on the cause of the blood in the urine.
Hope it helps. Take care and regards.
