Blood in the urine
It is never normal to see blood in the urine. If an infection is excluded, urgent arrangements should be made for review and investigation by a urologist. Investigations into the cause of blood in the urine (haematuria) include a telescopic examination of the bladder (cystoscopy) and an ultrasound scan of the kidneys. Further X-ray tests (IVU) and urine tests may also be necessary.
Your doctor may also suggest referral to a specialist for these investigations if ‘invisible’ blood is found on repeated urine testing at the surgery.
Bladder stones form when urine is retained in the bladder after having finished passing urine. Crystals are formed from chemicals in the urine and the crystals grow to form stones.
Bladder stones may cause no symptoms, but they can cause blood in the urine, infections, pain passing urine and the desire to pass urine frequently.
