What are the reasons for occult blood in urine during pregnancy? Urgent, thank you!

Patient's question:

No

Doctor's answer:

First, check if the patient has any symptoms, whether it was discovered during a physical examination or if there are symptoms such as frequent urination, urgency, dysuria, back pain, fever, edema, or hypertension. Assess the severity of hematuria, and check for any abnormalities in other urine tests, such as proteinuria, white blood cells, casts, etc. Additionally, it is important to consider the possibility of contamination during urination, such as vaginal bleeding polluting the urine.
Based on my assessment, it can be categorized as either infectious or non-infectious:
Infectious: Urinary tract infections are typically divided into upper and lower tract infections. Most patients exhibit symptoms, and urinalysis often shows an increase in white blood cells.
Non-infectious: Determine if the patient has urinary stones, a history of nephritis, or current kidney diseases such as chronic nephritis or IgA nephropathy, which often accompany symptoms like edema, hypertension, and proteinuria. Systemic diseases like lupus or Sj?gren's syndrome are less common, as are hematologic disorders with bleeding tendencies and urinary tract tumors.
It is recommended to visit a hospital for examination and relevant tests. If necessary, imaging studies such as ultrasound should be performed.
