Trial Outcomes & Findings for Development of an Intrauterine Pressure Threshold to Confirm Tubal Occlusion (NCT NCT04071392)

Results Overview

After placement of the hysterosalpingogram catheter, investigators use an infusion pump to deliver normal saline under continuous pressure monitoring until reaching one of the following endpoints: delivery of the entire volume of 10mL (milliliter); a peak pressure of 450mmHg (millimeters of Mercury); or the participant requested the infusion to stop due to intolerable discomfort. After one minute, investigators withdraw the delivered fluid through the hysterosalpingogram catheter and record the volume instilled and recovered. They then repeat the procedure using contrast under fluoroscopy to confirm tubal patency or occlusion.

Participant milestones
Measure	Post-Essure Group Healthy women with history of Essure hysteroscopic permanent contraception. Eligible participants will then undergo the HSG imaging study - a standard radiological imaging study to determine that the fallopian tubes are open and free of disease. It also checks the uterine cavity for any abnormalities. Hysterosalpingogram (HSG): An infusion pump delivered saline via balloon catheter under continuous pressure monitoring. After one minute, investigators withdraw the fluid and recorded volumes in and out. Subjects then undergo hysterosalpingogram (HSG) for evaluation of tubal patency.	Control Group Healthy women with no history of permanent contraception. Eligible participants will then undergo the HSG imaging study - a standard radiological imaging study to determine that the fallopian tubes are open and free of disease. It also checks the uterine cavity for any abnormalities. Hysterosalpingogram (HSG): An infusion pump delivered saline via balloon catheter under continuous pressure monitoring. After one minute, investigators withdraw the fluid and recorded volumes in and out. Subjects then undergo hysterosalpingogram (HSG) for evaluation of tubal patency.

SECONDARY outcome

Timeframe: 5 minutes

After placement of the hysterosalpingogram catheter, investigators use an infusion pump to deliver normal saline under continuous pressure monitoring until reaching one of the following endpoints: delivery of the entire volume of 10mL (milliliter); a peak pressure of 450mmHg (millimeters of Mercury); or the participant requested the infusion to stop due to intolerable discomfort. The proportion of participants who tolerated the full 10 ml of infused saline was compared between groups.
