Has anyone had a sonohysterogram (SHG) to check tubes are open?

I only had a sonohysterogram with saline (not an HSG), but when I reviewed my report it mentioned “open tube.” I was under the impression that a regular sonohysterogram isn’t the standard test for checking tubal patency, so I’m a bit confused.

Were any of you told your tubes were open based on a sonohysterogram alone? Was that considered reliable by your doctor, or did you still need an HSG/to confirm tubal patency?

I’m wondering if I should specifically request an HSG or if the sonohysterogram findings are usually enough.
