Blood in urine should be evaluated—even if it's painless
Seeing blood in urine can be frightening. Some people notice a pink tinge. Others see red urine or small clots. A common reaction is to hope it will "settle on its own" and avoid testing. Here is the medical truth: Blood in urine has many causes—some benign, some important. The safest approach is not panic; it is structured evaluation. Even when it is painless, it still deserves attention.
Quick navigation
First: what kind of blood are you seeing?
Doctors usually separate hematuria into two broad groups:
1) Visible blood (gross hematuria)
You can see it: pink, red, cola-colored, or with clots.
2) Microscopic blood
You can't see it; it is detected on urine testing.
Both deserve evaluation, but visible blood is more urgent to evaluate—especially if recurrent. Also note: Blood can appear at the start, end, or throughout the urine stream. This detail can help narrow causes, but you do not need to interpret it alone—just mention it.
Painless vs painful hematuria: why it matters
Blood + pain (especially flank pain)
Often suggests: stones, infection, inflammation. If the pain is severe or there is fever, urgency increases.
Blood without pain (painless hematuria)
This is the pattern that doctors take seriously because it can sometimes be an early sign of conditions that need timely diagnosis—especially in certain age groups and risk profiles. This does not mean it is cancer. It means it should not be dismissed. A structured evaluation is the right response.
Common causes
1) Stones
Stones can irritate the lining and cause blood, sometimes with pain, sometimes with mild discomfort.
2) Infection (UTI)
UTIs can cause blood, usually along with burning, urgency, and discomfort.
3) Prostate-related bleeding (in men)
In some men, prostate enlargement or inflammation can contribute to blood in urine—especially when there are also LUTS symptoms (weak stream, nocturia). But this is a diagnosis to reach after ruling out other causes.
4) Kidney or bladder causes that need evaluation
This includes a range of possibilities from benign lesions/masses to tumors. Again: not panic, but evaluation.
Go next if your doctor mentions a mass / abnormal imaging:
5) Medicines and medical conditions
Some medicines (including blood thinners) can increase bleeding tendency. But the presence of blood still requires evaluation; medicines do not automatically "explain away" the source.
Red flags: when you should go to emergency now
Please seek urgent care if you have:
- Heavy bleeding with clots
- Inability to pass urine (clot retention)
- Severe flank pain with fever/chills
- Fainting, severe weakness, very low urine output
- Vomiting with severe pain or fever
If you are safe and stable, you can still proceed with evaluation in a planned way.
What tests doctors usually do (and why)
Step 1: Urine routine microscopy + culture
Top urologists (like at MyDocsy) have a clear first goal - to locate the source and identify whether this is: infection/inflammation, stones/obstruction, a structural lesion in kidney/ureter/bladder, or other causes. Checks: infection, number of red blood cells, protein (important for kidney causes), other clues.
Step 2: Ultrasound (USG KUB + bladder; prostate in men)
Looks for: stones, kidney swelling, masses or suspicious findings, bladder wall changes, prostate size and residual urine (in men, if relevant).
Step 3: Risk-based imaging (if needed)
Depending on age, recurrence, and initial findings, doctors may advise: CT urogram (a detailed study of urinary tract) or other targeted imaging. This is not for everyone; it is used when needed.
Step 4: Cystoscopy (if needed)
Cystoscopy is a camera test to inspect the bladder. Many patients fear it unnecessarily. When a clinician recommends cystoscopy, it is because: hematuria is recurrent or unexplained, risk profile warrants direct bladder inspection, imaging does not fully explain the bleeding. The aim is clarity.
Step 5: Blood tests in selected cases
- Kidney function (creatinine/eGFR)
- Blood counts if bleeding is heavy
- Other tests based on context
A good evaluation by top doctors is not based on "do everything." It is "do the right next step."
What you can do right now
Unless you have an emergency, here are some practical, safe steps you can take at home:
1) Do not ignore it—even if it stops
Many causes bleed intermittently. The fact that it stopped does not always mean it is solved.
2) Hydrate steadily (unless your doctor restricted fluids)
This helps dilute urine and may reduce irritation, but it does not replace evaluation.
3) Avoid strenuous exercise temporarily
In some cases, heavy exertion can worsen bleeding. You want clean data for evaluation.
4) Do not self-start antibiotics without a urine test
If infection is present, targeted antibiotics are appropriate. But guessing can delay diagnosis.
5) If you have reports, keep them organized
Even a phone photo of: urine report, ultrasound report, CT report can help accelerate decision-making.

If you also have severe flank pain or stone-like pain
If burning urination / recurrent infections are prominent
If you're a man with LUTS symptoms (weak stream, nocturia) alongside blood
If your imaging mentions a "mass," "lesion," "tumor," or "growth"
