  • Introduction: Vesicouterine fistula is a rare kind of fistula with significant complications. In this report, we present a pregnant 39‐year‐old woman (gestational age: 20 weeks) who had symptoms of hematuria and abdominal pain. In the pelvic examination, she had some fetal tissue exiting from the cervix, leading to misdiagnosis of preterm labor. Further ultrasonographic examination showed that the fetus's body was detached from the head and moved through the fistula to the bladder. This case highlights the importance of assessing the bladder in women with a history of cesarean deliveries and hematuria, even while observing fetal tissue outside the cervix.
  • Methods: We report a case A 39-year-old pregnant woman, Gravida 7 Para 3, was admitted to a hospital in a rural area with gross hematuria the day prior to admission, following a day of heavy physical activity at home.
  • Results: During ultrasound examination, we found fetal body in the mother's bladder due to detachment and migration through the vesicouterine fistula, which is a rare kind of fistula.
  • Conclusion: Vesicouterine fistula is a rare condition that can cause significant complications. However, with early therapeutic management, patients can experience a better prognosis. In this report, we underscore the importance of utilizing ultrasonography as an accessible diagnostic tool for assessing women who present with hematuria, particularly those with a history of cesarean sections. Our case was a pregnant woman, with detachment of the fetal body and head, which led to moving the head towards the cervix and moving the body towards the bladder. The presence of fetal tissue outside the cervix suggested the diagnosis of preterm labor, but the radiologist's attention to the bladder in ultrasonography revealed the true diagnosis of fetal presence in the bladder. Therefore, we strongly recommend that when fetal tissue is observed in the cervix, indicating preterm labor, physicians should consider the assessment of the bladder in the presence of hematuria.
