Placenta implantation in the bladder is usually not felt in the early stages, but if the implantation is too deep you may experience abdominal pain and hematuria. Placenta implantation in the bladder is usually not felt in the early stages and is usually detected during ultrasound examination. As the placenta continues to grow, the depth of its invasion into the bladder increases, which can lead to bladder irritation signs of frequent urination, urinary urgency, and painful urination in pregnant women. Due to the invasion of bladder mucosa can also lead to abdominal pain, bladder bleeding, manifested as hematuria. At the same time, as placenta implantation bladder is more likely to cause hemorrhage when the bladder is handled during delivery, adequate pre-operative and intra-operative preparations are needed, so timely medical consultation and treatment are needed when placenta implantation bladder is suspected or diagnosed.
