The purpose of this study is to determine if the device is supplying sufficient diagnosis results of an internal rectal prolapse, of a pelvic floor ptosis and for the determination of an interal hernia into the Douglas pouch, as well as to determine the technical success of using the device at the patient.

Existing diagnosis methods are inadequate, inaccurate, complicated or can only made intraoperatively. The new device should enable a fast and easy examination procedure well tolerated by the patients. The diagnosis results, received with the device, should assist in the accurate selection of patients for operations as well as to avoid any unnecessary operations.
