Blood in the urine

Blood in the urine, also known as hematuria, is a medical condition characterized by the presence of red blood cells (erythrocytes) in the urine. It can be categorized into two types: microscopic hematuria and gross hematuria.

Causes[edit | edit source]

Blood in the urine can be caused by a variety of conditions, including:

Urinary tract infections (UTIs): These are often caused by bacteria that enter the urethra and travel to the bladder.
Kidney infections: These occur when bacteria enter the kidneys, usually through the bloodstream.
Kidney stones: These are hard deposits of minerals and salts that form inside the kidneys.
Bladder stones: These are hard masses of minerals in the bladder.
Kidney disease: Various diseases can cause kidney damage, including diabetes and high blood pressure.
Cancer: Blood in the urine can be a sign of kidney or bladder cancer.

Diagnosis[edit | edit source]

Diagnosis of blood in the urine typically involves a series of tests, including:

Urinalysis: This is a test of a urine sample to check for various substances, including blood, protein, and bacteria.
Imaging tests: These may include a CT scan, MRI, or ultrasound to visualize the urinary tract and kidneys.
Cystoscopy: This is a procedure to examine the inside of the bladder and urethra.
