Hematuria means blood in the urine. It may be visible — turning urine pink, red, or brown — or microscopic, found only on a urine test. Either way, the same principle applies: it has a cause worth identifying, and the sooner the better.
Why it shouldn’t be ignored
Many causes of blood in the urine are benign and easily treated. But it can also be the first and only warning sign of bladder or kidney cancer, often before any other symptom appears. Catching those early dramatically changes outcomes — which is why even a single episode deserves a look.
One episode is enough reason to be seen. Blood in the urine can come and go. Waiting for it to return can delay finding — and treating — the cause early.
Common causes
- Urinary tract infections
- Kidney or bladder stones
- Enlarged prostate (BPH)
- Vigorous exercise or certain medications
- Bladder or kidney tumors (which is why evaluation matters)
How we evaluate it
Dr. Shusterman uses an efficient, thorough workup designed to find the source without unnecessary steps. Depending on your situation it typically includes:
- A urinalysis to confirm and characterize the bleeding
- Imaging of the kidneys and urinary tract
- A cystoscopy — a quick, in-office look inside the bladder using a thin scope
In most cases the cause is identified promptly, and the great majority of patients leave reassured with a clear plan.
Common questions
Is blood in the urine serious?
It ranges from harmless to serious and always deserves evaluation. Common causes include infection, stones, and an enlarged prostate — but it can also be the first sign of bladder or kidney cancer, which is why it shouldn’t be ignored.
What if I only saw it once?
Even one episode of visible blood warrants evaluation. It can be intermittent, so waiting risks delaying an early, treatable diagnosis.
What does the workup involve?
Usually a urinalysis, imaging, and often a quick cystoscopy to look inside the bladder. The goal is to find the source efficiently and put your mind at ease.
