Ultrasound examination and macroscopic findings of the implantation site: Ultrasound of the bladder at 1 month after implantation (A). A thickened bladder wall with irregular margins was observed at the implantation site (yellow arrowhead). Ultrasound of the bladder 3 months after implantation (B). The thickening resolved and the bladder lumen appeared smooth. The yellow arrowhead indicates the suture. Macroscopic finding 1 month after implantation (C). The omentum was strongly adhered to the implantation site, which was stiff and had little flexibility. Macroscopic finding 3 months after implantation (D). Although there was still adhesion of the omentum, the implantation site had regained a flexibility similar to that of a native bladder wall.
