Despite being non-life threatening, uterine prolapse is a reproductive health problem that interferes psychosocial life, economical and sexual function. Uterine prolapse can be caused by direct trauma resulting in damaged and weakened levator ani muscle which in turn causing sacrouterine ligament to stretch in order to maintain uterus normal position. The main component of sacrouterine ligament is collagen. Types of collagen that was involved in the occurrence of uterine prolapse are which plays a role of risk of occurrence uterine prolapse is collagen type-1 and type-3. Collagen type-1 has a good resistance and flexible to strain. If there is a disruption in the expression of collagen in sacrouterine ligament, it will result in cause uterine prolapse. The aim of this study is to prove low expression of collagen type-1 in sacrouterine ligament is a risk factor for the occurrence of stage III-IV uterine prolapse. This study was an observational study using case-control approach. A total of 22 cases of stage III-IV uterine prolapse and 22 cases of non-uterine prolapse as control group were selected by consecutive sampling. This study was carried out in Sanglah General Hospital and Pathobiology Laboratory of Veterinary Faculty of Udayana. Samples were taken from sacrouterine ligament of individual with stage III-IV uterine prolapse compared to non-prolapse uterine who had undergone total hysterectomy. Chi-square analysis with 95 % confidence interval indicated that low expression of collagen type-1 was 6 times more likely to be the risk factor of stage III-IV uterine prolapse (OR = 5.95; 95 %CI = 1.59-22.33; p = 0.006). Low collagen type-1 in sacrouterine ligament is a risk factor of stage III-IV uterine prolapse. Copyright © 2020. Published by Elsevier B.V.
