Blood in the urine

Blood in the urine, medically known as hematuria, can be a serious symptom indicating various underlying conditions. There may be both visible (macroscopic) blood and non-visible (microscopic) blood in the urine, which can only be detected by laboratory tests.

Causes of blood in the urine

Blood in the urine can be triggered by a variety of causes. The most common include urinary tract infections, kidney stones, bladder stones, injuries to the urinary tract, certain medications and intense physical activity. Other possible causes include tumors in the bladder or kidney, kidney disease, prostate enlargement and genetic disorders such as Alport syndrome.

Symptoms of blood in the urine

  • Reddish or brown discoloration of the urine
  • Pain or burning sensation when urinating
  • Frequent urge to urinate
  • Pain in the lower abdomen or in the flank area
  • In microscopic hematuria, there are no visible symptoms, only laboratory tests show blood in the urine

Diagnosis of blood in the urine

Diagnosis begins with a thorough medical history and physical examination by a urologist. Diagnostic procedures include urinalysis, blood tests, ultrasound, CT scans and cystoscopy. These tests help to identify the cause of hematuria and determine the best course of treatment.

Treatment options for blood in the urine

Conservative: Treatment of the underlying cause, such as antibiotics for urinary tract infections or adjustment of medications that cause hematuria.

Medication: Painkillers and medication to treat specific causes such as infections or inflammatory diseases.

Ergonomic aids: use of special bladder catheters for urinary tract injuries or obstructive problems.

Surgical: In severe cases, surgery may be required to remove tumors, remove bladder stones or correct other structural problems.

Follow-up: Regular follow-up examinations to ensure that the hematuria has been successfully treated and no further complications occur.

Preventive measures for blood in the urine

To reduce the risk of blood in the urine, you should drink enough water to flush the urinary tract and have regular visits to the doctor for early detection of urinary tract disease. It is also important to moderate intense physical activity and take protective measures during hazardous activities to avoid injury.
