Sonohysterography can detect polyps, submucosal fibroids, endometrial atrophy, uterine septa, endometrial hyperplasia or suspected neoplasia with high sensitivity. Sonohysterography can be easily performed in the office using a transvaginal ultrasound probe and commercially available HSG catheters. After emptying her bladder, the patient is placed in dorsal lithotomy position. The ultrasound probe is covered with a condom and inserted into the anterior fornix of the vagina. A baseline transvaginal ultrasound scan is performed.
Endometrial thickness is measured and the shape of the endometrium is noted.
The ultrasound probe is removed and a speculum is placed in the vagina and the cervix is cleaned with betadine swabs. A standard 2 mm HSG catheter with a 3 mm balloon is passed through the cervix. The balloon is inflated with 2-3 cc. of saline. The speculum is then removed and the transvaginal probe is introduced. This procedure is safe and well tolerated by patients.
