Saline-infusion
sonohysterography (or hysterosonography) is a procedure
that allows a
more detailed view of the inner lining of the uterus (endometrium) than
is possible with standard pelvic ultrasound. This is achieved by
filling the uterine cavity with sterile salt water through a thin
plastic catheter that is placed at the cervix and then taking
ultrasound images. The water outlines any polyps or tumors of the
endometrium that may be present. The number and location of polyps are
easily assessed, which is information that can guide the gynecologist
when performing a D&C procedure.
Situations when sonohysterography can be useful include abnormal
vaginal bleeding, heavy periods, and a thickened or abnormal-appearing
endometrium on standard pelvic sonography.

web
