Abstract

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.
