The procedure is usually performed in an outpatient setting and takes about 15-30 minutes. The patient lies on an examination table, and a speculum is inserted into the vagina. A thin catheter is then placed through the cervix into the uterine cavity, and saline is slowly infused. Concurrently, a transvaginal ultrasound probe is used to capture images. The process may cause mild cramping, but it is generally well-tolerated.
