Hematuria means that red blood cells are in the urine, the condition that causes bleeding after urination. The National Kidney and Urologic Diseases Information Clearinghouse says bleeding after urination may indicate minor conditions or serious problems that require medical intervention.

Strep Throat

Post-streptococcal glomerulonephritis, a kidney condition after strep throat, causes blood in children's urine. MedlinePlus Medical Encyclopedia says the infection makes the blood vessels in the kidney become inflamed.

Polycystic Kidney Disease

Polycystic kidney disease causes bleeding after urination. MedlinePlus states that this genetic condition occurs because multiple cysts enlarge the kidney, leading to an overproduction of red blood cells.

Urinary Tract Procedures

Urinary tract procedures may trigger the appearance of drops of blood after urination. These procedures include catheterization, circumcision, kidney biopsies and surgeries.

Additional Symptoms

See your doctor if blood in urine, especially when accompanied by weight loss, abdominal pain, frequent and uncomfortable urination, blood clots in urine and pain after intercourse.

Diagnostics

Doctors perform a series of examination to determine the seriousness of your bloody discharge. The National Kidney and Urologic Diseases Information Clearinghouse says diagnostics include blood tests, urinalysis, ultrasounds and cystoscopes--small cameras on thin tubes.

Treatments

Treatments for minor conditions clear up on their own or require antibiotics. Serious health problems require surgery, treatments for bladder cancer or bone marrow transplants.
