what does the presence of blood in urine indicate?

Answer 1

Most likely a urinary tract infection.

Answer 2

The well-known causes of blood in the urine include the following:

Kidney stones

Infections - Of the urinary tract or genitals, especially in women

Blockage of the urinary tract, usually the urethra - By a stone, a tumor, a narrowing of the opening (stricture), or a compression from surrounding structures

Cancer of the kidney, bladder, or prostate

Kidney disease

Blood clotting disorders

Injury to the upper or lower urinary tract, as in a car wreck or a bad fall

Medications - Antibiotics (for example, rifampin), analgesics such as aspirin, anticoagulants (blood thinners such as warfarin), phenytoin, quinine

Benign (noncancerous) enlargement of the prostate - Known as benign prostatic hypertrophy (BPH), a common condition in older men

Chronic diseases such as diabetes, hypertension, and sickle cell anemia

Viral infections

Inflammation of the kidney - Usually of unknown cause

Strenuous exercise, especially running - Results from repeated jarring of the bladder
Sometimes no cause is found for blood in the urine.

If serious conditions such as cancer, kidney disease, and other chronic diseases that cause kidney damage or bleeding are ruled out, the cause is almost certainly not serious.

The hematuria will probably go away by itself or continue as a chronic condition without doing harm.
Urine can be colored pink, red, or brown for reasons that have nothing to do with bleeding in the urinary tract.

Foods - Beets, berries, rhubarb in large amounts

Food coloring

Medications - Certain laxatives and pain medications

Menstrual blood

Liver diseases - Also can be very serious

Answer 3

It is a sign of a large number of diseases of the kidneys and the urinary tract, ranging from trivial to lethal.
The condition is called hematuria.

causes:

Benign familial hematuria (a thinning of the basement membrane of the glomeruli in the kidneys)

Urinary Schistosomiasis (caused by Schistosoma haematobium) - a major cause for hematuria in many African and Middle-Eastern countries;

IgA nephropathy ("Berger's disease") - occurs during viral infections in predisposed patients;

Kidney stones (or bladder stones, now a rare disease);

Bladder cancer;

Renal cell carcinoma - occasionally presents with bleeding;

Paroxysmal nocturnal hemoglobinuria - a rare disease where hemoglobin of hemolysed cells is passed into the urine.

Urinary tract infection with some bacterial species including strains of EPEC and Staphylococcus saprophyticus

Sickle cell trait can precipitate large amounts of red blood cell discharge, but only a small number of individuals endure this problem

Arteriovenous malformation of the kidney (rare, but may impress like renal cell carcinoma on scans as both are highly vascular)
