Fetal Presence in the Bladder Detected on Ultrasound: A Case Report.

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.
