During a saline sonogram, the physician will place a small amount of sterile water in the uterus while he/she is performing an ultrasound. The water opens up the uterine cavity slightly so that the physician can look for abnormalities inside the uterus such as polyps, scar tissue, fibroids, or other abnormalities.
During the procedure, the physician will place a speculum in the vagina, then pass a very small catheter through the natural opening in the cervix. The physician will then deliver water through that catheter while they perform a transvaginal ultrasound. This is a relatively painless procedure, however some patients may experience slight discomfort, light cramping or spotting, all of which subside quickly.
When the procedure is complete, the physician can review the findings with you immediately and discuss options for addressing any areas of concern, if present.
