Analysis of collagen in parametrium and vaginal apex of women with and without uterine prolapse

Our objective was to compare the amount of collagen in parametrium and vaginal apex between women with uterine prolapse at pre- and postmenopause, and in women without prolapse. the study included 22 premenopausal women without prolapse (group A), 10 premenopausal women with prolapse (group 13), and 23 postmenopausal women with prolapse (group Q (total 55). Patients in group A underwent abdominal hysterectomy for uterine leiomyoma, and patients in groups B and C underwent vaginal hysterectomy. During the surgical procedure we obtained biopsies from the lateral parametrium and vaginal apex. the tissue was stained for histological analysis with picrosirius. We observed a lower amount of collagen in the parametrium of women with uterine prolapse, both in menacme and in postmenopause, than in the parametrium of women without prolapse. We observed no statistically significant difference in vaginal apex between the groups.Universidade Federal de São Paulo, São Paulo, BrazilUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc
