Hematuria (blood in the urine)
A symptom that needs to be investigated without delay
Hematuria refers to the presence of blood in the urine, whether visible to the naked eye (macroscopic hematuria) or detectable only under a microscope.
Understanding, diagnosing, and treating the cause of urinary bleeding
Hematuria is the presence of blood in the urine, whether visible to the naked eye (macroscopic hematuria) or detectable only under a microscope (microscopic hematuria). It is a symptom that should never be ignored , as it can indicate a problem with the kidneys, ureters, bladder, or prostate. Dr. Sébastien Dominique , a urologist in Paris, conducts a comprehensive evaluation to identify the cause of the bleeding and propose appropriate treatment, favoring precise diagnostic techniques and minimally invasive procedures when necessary.
What are the possible causes?
How does the diagnosis process work?
The treatment is based on a structured assessment to identify the origin of the bleeding.
- Urine analysis (ECBU) to rule out infection
- Urine cytology to detect abnormal cells
- CT scan or ultrasound to visualize kidneys, ureters and bladder
- Cystoscopy : an essential examination for directly visualizing the bladder and urethra
- Blood tests depending on the situation (kidney function, coagulation)
Dr. Dominique systematically adapts the assessment according to age, risk factors and the mode of onset of hematuria.
Possible treatments
Once the cause is identified, the treatment is targeted:
Antibiotics for infection; minimally invasive treatment or surgery for urinary stones; endoscopic removal of a bladder tumor; treatment of BPH if the prostate is involved; simple monitoring if the cause is benign and confirmed.
The goal is always to treat the cause , stop the bleeding, and prevent recurrence.

FAQ – Frequently Asked Questions
Is the presence of blood in the urine always serious?
No, but it should always be investigated. Hematuria can come from an infection, a stone or an enlarged prostate, but it can also reveal a tumor of the bladder or kidney: no episode should be neglected, even isolated and painless.
What tests are performed in cases of hematuria?
The assessment includes a urine test (ECBU, urine cytology), a CT urogram to explore the kidneys and ureters, and a cystoscopy (fibroscopy of the bladder) performed in consultation under local anesthesia.
Should you consult a doctor even if the bleeding has stopped?
Yes, absolutely. Intermittent hematuria is common, including in bladder tumors: the disappearance of the bleeding does not mean the cause has disappeared. A complete evaluation remains essential.
Can certain medications or foods color urine?
Yes: beets, blackberries, and certain medications (rifampicin, vitamin B12, etc.) can turn urine red without actual bleeding. Only a cytobacteriological examination can confirm or rule out the presence of blood.
