Blood in urine can have various causes, ranging in severity from 'needs attention' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose blood in urine, we could:
Cause | Probability | Status |
---|---|---|
Bladder Cancer | 93% | Confirm |
Glomerulonephritis | 14% | Unlikely |
Kidney Stones | 2% | Ruled out |
Urinary Tract Infection | 2% | Ruled out |
Do you ever see blood in your urine?
Possible responses:
→ No / don't know→ Yes, once or twice recently → Yes, occasionally → Yes, regularly |
Blood in the urine, pain while urinating, and a frequent need to urinate even if the bladder is empty are the main symptoms of bladder cancer. However, these symptoms can also indicate bladder infections, stones or benign tumors, so a medical diagnosis is necessary to rule out or confirm cancer of the bladder.
For some patients, IgAN first appears as an acute glomerulonephritis with macroscopic hematuria (visible blood in the urine). In this case patients are visibly sick enough to seek medical attention, and may exhibit any or all the symptoms of acute glomerulonephritis.
The bleeding may be caused by abrasion along the urinary tract as the stone travels.
