Microscopic Haematuria is the presence of blood in the urine which cannot be detected by the naked eye, but only picked up by a urine test where the urine is studied under the microscope for red blood cells (RBCs), white blood cells (WBCs), epithelial cells (ECs) [vaginal cells], and bacteria (germs).
Microscopic Haematuria can be caused by:
- Urinary tract infection (UTI)
- Kidney and/or bladder stone/s
- Kidney and/or bladder tumour which may be benign or malignant (non-cancerous or cancerous).
- Foreign body in the bladder, e.g., suture, tape or mesh
- Radiation cystitis (radiation treatment to the bladder or pelvis)
- Interstitial cystitis: a type of chronic cystitis; now known as painful bladder syndrome
- Urogenital syndrome: post menopausal changes to the urinary tract and female genital organs, i.e., thinning and dryness caused by the decreased blood flow because of the very low female hormone, oestrogen, after the menopause
- Pyelonephritis (inflammation of the kidneys)
