Abstract Introduction and hypothesis We aimed to summarize the knowledge on the pathogenesis of pelvic organ prolapse (POP) generated in animal models. Methods We searched MEDLINE, Embase, Cochrane and the Web of Science to establish what animal models are used in the study of suggested risk factors for the development of POP, including pregnancy, labor, delivery, parity, aging and menopause. Lack of methodologic uniformity precluded meta-analysis; hence, results are presented as a narrative review. Results A total of 7426 studies were identified, of which 51 were included in the analysis. Pregnancy has a measurable and consistent effect across species. In rats, simulated vaginal delivery induces structural changes in the pelvic floor, without complete recovery of the vaginal muscular layer and its microvasculature, though it does not induce POP. In sheep, first vaginal delivery has a measurable effect on vaginal compliance; measured effects of additional deliveries are inconsistent. Squirrel monkeys can develop POP. Denervation of their levator ani muscle facilitates this process in animals that delivered vaginally. The models used do not develop spontaneous menopause, so it is induced by ovariectomy. Effects of menopause depend on the age at ovariectomy and the interval to measurement. In several species menopause is associated with an increase in collagen content in the longer term. In rodents there were no measurable effects of age apart of elastin changes. We found no usable data for other species. Conclusion In several species there are measurable effects of pregnancy, delivery and iatrogenic menopause. Squirrel monkeys can develop spontaneous prolapse.

Levator Ani Muscle Avulsion

Pelvic floor dysfunction (PFD) due to vaginal delivery is related to tear of levator ani muscle (LAM) that potentially lead to the impairment of quality of life among women. A number of attempts to predict LAM injury after vaginal delivery had been conducted. This study aims to appraise the accuracy of several prediction index determining LAM injury after vaginal delivery. We conducted a search in Cochrane Library®, Pubmed®, and Medline® with the keywords of “pelvic floor dysfunction” AND “vaginal delivery” AND “prediction.” Critical appraisal determining the validity, importance, and applicability (VIA) was conducted by 2 independent authors. After 6 weeks to 3 months’ duration of follow up, the incidence of LAM avulsion was varied from 15.4% to 35.6% from three studies. Multivariate analysis showed that forceps delivery, OASIS, and active second stage (OR 3.8; 3.1; 1.61; respectively) as the most influential factors for LAM incidence. Maternal age and time spent in active pushing were also contributed to LAM incidence. OASIS and second stage of labor could be used as the most influential components of prediction index for LAM incidence. Prediction indexes for LAM incidence are developed. OASIS and second stage of labor are acknowledged as two most influential variables among three appraised studies.
