A simple technique for visualization of the vagina during ultrasound scanning.

A simple method for clear visualization of the vagina during ultrasound scanning is described. A sealed cylinder, filled with water, is introduced into the vagina. This device, used when the urinary bladder is full, improves visualization of the pelvic organs and facilitates interpretation of the scans. The technique may be employed during all stages of pregnancy, provided there is no bleeding or dilatation of the cervix.
