Location of the endometrial polyp and its pregnancy rate of infertility patients

Abstract

To assess endometrial polyp location and abnormal endometrial findings and their impact on pregnancy rate. Retrospective study. A retrospective study was conducted on 230 infertility patients who had an endometrial polyp suspected ultrasound and diagnosed by hysteroscopy. Polyp was taken out by either polypectomy or curettage. All specimens were pathologically examined. The endometrial cavity was subdivided into five areas: utero-tubal junction, anterior uterine wall, posterior uterine wall, lateral uterine wall, and multiple. The patients received up to six months of follow-up; pregnancy rates were compared between the five subdivisions. The incidence of endometrial polyps by location was: utero-tubal junction, 8.0%; posterior uterine wall, 32.0%; anterior uterine wall, 15.4%; lateral uterine wall, 9.2%; and multiple, 35.4%. The pregnancy rate by location after operation was: utero-tubal junction, 57.4%; posterior uterine wall, 28.5%; anterior uterine wall, 14.8%; lateral uterine wall, 18.8%; and multiple, 40.3%, respectively. Endometrial hyperplasia was found in 6.9% of the cases. The pregnancy rate after operation in utero-tubal junction was significant higher than that of others. Endometrial polyps are commonly found on the posterior wall of the uterus; however, excision of polyps located at the utero-tubal junction significantly improved the pregnancy rate. Endometrial polyps should be categorized for both size and location.
