Microscopic hematuria is a condition in which urine contains blood that is not visible to the naked eye and can be detected only by a urine test. The urine is examined under microscope to identify different cells such as red blood cells (RSCs), white blood cells (WBCs), epithelial cell (ECs) and bacteria.
Microscopic hematuria often has no symptoms and is most commonly detected as part of a urine test at your routine medical check-up. Patients with microscopic hematuria may feel pain or burning sensation with urination or increased frequency of urination.
The possible causes of microscopic hematuria include:
- Urinary tract infection (UTI)
- Kidney or bladder stone
- Benign or malignant tumour in kidney or bladder
- Radiotherapy of bladder or pelvis
- Painful bladder syndrome
- Urogenital syndrome Inflammation of the kidneys (Pyelonephritis)
To find the cause of hematuria the doctor may order a series of tests which include
- An ultrasound scan of the kidneys and bladder
- Cystoscopy: A cystoscopy is an examination of the inside of the bladder and urethra, the tube that carries urine from the bladder to the outside of the body
The treatment of microscopic hematuria depends on the underlying cause. Your doctor will focus on treating the underlying cause to help prevent it from recurring.
