Haematuria refers to the presence of red blood cells in urine, which can manifest in two forms. Gross haematuria is visible blood that turns urine pink, red, or cola-coloured, while microscopic haematuria is only detectable through laboratory testing. This condition occurs when blood enters the urinary tract anywhere from the kidneys to the urethra.
The urinary system includes the kidneys, ureters, bladder, and urethra (and prostate as well in men), and bleeding can originate from any of these structures. While haematuria itself is a symptom rather than a disease, it serves as an indicator that requires medical evaluation. The amount of blood present doesn’t necessarily correlate with the severity of the underlying condition – even small amounts warrant investigation.
Many conditions can cause haematuria, ranging from urinary tract infections and kidney stones to more serious conditions (such as cancer) requiring prompt treatment. The key lies in accurate diagnosis through systematic evaluation by an experienced urologist who can differentiate between various causes and recommend appropriate management.
