A hysterosonography is an ultrasound with an infusion of saline. Hysterosonography, also known as sonohysterography, incorporates a screening process that checks for intrauterine abnormalities for those couples with infertility problems. An ultrasound image is produced that views the uterine cavity and the endometrial lining. This procedure also tests for the presence of congenital defects, masses, scarring, polyps or fibroids.
During the procedure, sterile saline is infused into the uterus to enlarge the cavity and make any problems more visible. A probe is inserted into the vagina to obtain the sonogram images. The procedure is non-invasive and usually takes about 30 minutes.
