Abstract

Introduction and Hypothesis: Pelvic organ prolapse (POP) severity is poorly correlated with prolapse symptoms. The objective of this study was to investigate the association between genital hiatus (GH) size and presence and severity of bulge symptoms. Methods: This analysis utilized data from a longitudinal study of parous women. Women underwent annual assessment of POP, GH size, and bulge symptoms. “Bother” was scored by participants reporting bulge symptoms. Three analyses evaluated the association between GH size and bulge symptoms, each using linear mixed models. First, we compared case visits (bulge symptoms reported) to control visits (bulge symptoms never reported), matching for stage. Second, among women who reported bulge sensation at least once during the study, we compared GH size at visits with and without bulge symptoms. Third, among women who reported bulge sensation, we investigated whether GH size was associated with “bother” score, controlling for stage. Results: Of 1528 women (7440 visits), 148 women (803 visits) reported bulge symptoms at ≥ 1 visit and 1380 women never reported bulge symptoms (6637 visits). Comparing 315 case visits (bulge symptoms reported) to 1260 control visits (bulge symptoms never reported), GH size was significantly greater among case visits (3.05 cm versus 2.85 cm, p ≤ 0.0001). In the case-crossover analysis, GH size was similar for visits with and without bulge symptoms (p = 0.63). When evaluating GH size and degree of bulge symptom bother, bother severity was significantly associated with GH size (p = 0.003). Conclusions: Independent of stage, GH size was significantly associated with prolapse bulge symptoms and bother severity.
