Objective: Pelvic organ prolapse (POP) can happen if the support tissues are weak or damaged, or if the pelvic floor muscles are weak and saggy. POP tends to be more likely after childbirth, menopause or overweight. Although it is better to prevent POP than try to fix it, there was little way to prevent except for the pelvic floor muscles training. Besides, this is an uncomfortable condition that affects one in three women, however, it is a hidden problem many people aren’t comfortable talking about. Thus, this study proposed a method to self-check with the vaginal endoscope which was made through a three-dimensional printing. Methods: The prototype design was divided into two parts: flexible material for inserting into and contacting with the wall of vagina, and rigid body for observing. While putting air in the material through the rigid body, the camera which was set to the tip of rigid body could observe the inside of vagina. The position and orientation of camera was measured with two sensors. The provided air pressure was possible to estimate the pressure inside of vagina. Results: The forced disturbance from the test bed which was made to confirm the effectiveness enabled us to perceive the position and degree of disturbance which was regarded as the early stage of prolapse. Discussion: It was discussed that the continuous observation through 3D-printing-based vaginal endoscope helped prevent POP because the low-cost design was possible to self-check anytime.
