Similarly, an observational prospective cohort study of 225 women who had undergone a cesarean section 6-12 months prior compared TVUS and gel-infused sonohysterogram (GIS) and found that the prevalence of a niche--defined as an anechoic area at the site of the cesarean scar, with a depth of at least 1 mm on GIS--was 24% with TVUS and 56% with GIS (Ultrasound Obstet.
A saline-infused sonohysterogram is a superior diagnostic tool for evaluating isthmoceles.
He and his associates compared 200 premenopausal women who had endometrial thickness measurements taken before having a sonohysterogram (SHG) to investigate abnormal uterine bleeding.
It's probably better to do an ultrasound to assess the overall morphology of the endometrium and then perform a sonohysterogram in virtually all patients, unless it's completely obvious that there's something there," Dr.
I don't care how good an ultrasonographer you are, you can't rule out mucosal or submucosal involvement of fibroids just on the basis of ultrasound unless you perform a sonohysterogram
, which was not done in this study.
Bleeding was assessed via menstrual calendars, and endometrial thickness was remeasured at the end of the study by ultrasonography or in some cases saline infusion sonohysterogram
Be sure to schedule the sonohysterogram
at the tail end of the bleeding, when the endometrium is in its thinnest and most uniform state.
