This study is to review how the uterus heals after having open fetal surgery. Open fetal surgery causes a scar perhaps two: one from the open fetal surgery and a second from delivery by cesarean section; rarely, the same area of your uterus was used for both open fetal surgery and delivery. From other studies of surgery performed on a uterus, some of the uterine scars do not heal well. This study's intervention uses sterile saline to spread open the inside of the uterus. The saline is slowly injected into the uterus using a catheter. An ultrasound called a sonohysterogram is performed to take pictures of the uterus, its inside and the walls of the uterus. In this way, the healed areas from the uterine surgery can be seen with ultrasound and evaluated. This is performed at least 6 months after delivery. Primary Outcome: Measure the depth of the scar and location of the scar 6 months or longer after delivery.
