OBJECTIVE: The objective was to determine if intrauterine pressure can distinguish bilateral tubal occlusion (BTO) from unilateral or bilateral tubal patency (TP) in women following a permanent contraception procedure.
STUDY DESIGN: We used a small inline pressure sensor to continuously monitor intrauterine pressure during hysterosalpingogram (HSG) in a cross-sectional study that enrolled women having HSGs for any indication. The primary outcome was the peak intrauterine pressure compared between women with BTO and TP as verified by HSG.
RESULTS: We enrolled 150 subjects, of which 111 (74.0%) provided usable pressure readings. Of these, 98/111 (88.3%) had TP, and 13 (11.7%) had BTO. There was no difference in peak intrauterine pressure for subjects with TP (mean 293.8±58.7 mmHg) compared to those with BTO (292.7±71.3 mmHg, p=.95). Among parous women, peak intrauterine pressure in subjects with BTO (311.9±78.0 mmHg) was higher but not significantly different from subjects with TP (282.7±49.2 mmHg, p=.20). In linear regression analysis, peak intrauterine pressure was not associated with age, body mass index, gravidity or having at least one prior live birth.
CONCLUSIONS: Measurement of peak intrauterine pressure does not distinguish between women with patent and blocked fallopian tubes. This approach would not be clinically useful to verify occlusion following permanent contraception.
IMPLICATIONS: Peak intrauterine pressure does not differ between women with patent and occluded fallopian tubes and cannot be used to confirm tubal occlusion after nonsurgical permanent contraception.
