Single Most Likely Diagnosis
- Urinary Tract Infection (UTI): This is a common condition in pregnant women due to physiological changes that can predispose them to infection. The presence of blood in the urine (hematuria) can be a symptom of a UTI.
Other Likely Diagnoses
- Kidney Stones: Pregnancy increases the risk of kidney stones due to increased urine concentration and other physiological changes. Hematuria is a common symptom.
- Pregnancy-related Hematuria: Mild hematuria can sometimes be seen in pregnancy due to the mechanical effects of the enlarged uterus on the ureters and bladder.
Do Not Miss Diagnoses
- Placenta Previa: Although less common, this condition, where the placenta covers the cervical os, can cause painless vaginal bleeding, which might be mistaken for hematuria if the blood is mixed with urine. It's crucial to differentiate between vaginal and urinary bleeding.
- Preeclampsia with Renal Involvement: Preeclampsia can lead to renal complications, including hematuria. Early detection is critical for managing the condition and preventing severe outcomes.
Rare Diagnoses
- Glomerulonephritis: An inflammation of the glomeruli, which can be caused by various factors, including autoimmune diseases. It's less common but can present with hematuria.
- Malignancy (e.g., Bladder or Renal Cancer): Although rare, especially in younger pregnant women, any unexplained hematuria warrants a thorough investigation to rule out malignancy.
