What causes occult blood in urine during physical examination

Physical examination of occult blood in urine may be caused by urinary system stones, urinary tract infections, nephritis, urinary system tumors, or vigorous exercise. Urinary occult blood usually manifests as the presence of red blood cells in the urine, which may be accompanied by symptoms such as frequent urination, painful urination, and lower back pain. It is recommended to seek medical attention promptly and receive targeted treatment after identifying the cause.

1. Urinary system stones

Urinary system stones may lead to occult blood in urine, which may be related to factors such as insufficient water intake and high salt diet. They usually manifest as symptoms such as lower back pain and hematuria. During treatment, medication such as Paishi Granules and Urinary Stones Pill can be used according to medical advice, and extracorporeal shock wave lithotripsy may be performed if necessary.

2. Urinary tract infection

Urinary tract infection may cause occult blood in urine, which may be related to bacterial infection, poor hygiene habits, and other factors. It usually manifests as symptoms such as frequent urination, urgency, and pain during urination. During treatment, medication such as levofloxacin hydrochloride capsules and cefepime dispersible tablets can be used according to medical advice, while also drinking plenty of water.

3. Nephritis

Nephritis may lead to occult blood in urine, which may be related to factors such as streptococcal infection and immune abnormalities. It usually manifests as symptoms such as edema, hypertension, and proteinuria. During treatment, medications such as acetate prednisolone tablets and Tripterygium wilfordii Hook. f. polysaccharide tablets can be used according to medical advice, and salt intake should be restricted.

4. Urinary system tumors

Urinary system tumors may cause occult blood in urine, which may be related to long-term smoking, exposure to chemicals, and other factors. They usually present as painless hematuria, weight loss, and other symptoms. Diagnosis needs to be confirmed through cystoscopy, CT and other examinations, and treatment methods include surgical resection, radiotherapy, etc.

5. Intense exercise

Intense exercise may lead to transient occult blood in urine, which may be related to changes in renal blood flow during exercise, usually without other discomfort symptoms. This situation is mostly physiological and can be relieved on its own after rest, without the need for special treatment, but excessive exercise should be avoided. After discovering occult blood in urine, excessive tension should be avoided, and physiological factors such as menstrual period and vigorous exercise should be ruled out first. Maintain a daily water intake of at least 2000 milliliters, avoid holding urine, and reduce a high salt and high-fat diet. If urinary occult blood persists or is accompanied by other symptoms, it is necessary to seek medical attention promptly at the nephrology or urology department, and complete urine routine, urinary system ultrasound and other examinations. Long term smokers should quit smoking, and those who come into contact with chemicals should take occupational protection measures. Women should pay attention to genital hygiene to prevent urinary tract infections.
