Pregnancy Rate after Myomectomy and Associated Factors among Reproductive Age Women Who Had Myomectomy at Saint Paul’s Hospital Millennium Medical College, Addis Ababa: Retrospective Cross-Sectional Study

Abstract

Introduction. Uterine myoma occurs in 20-50% of reproductive age women. Uterine myomas may be associated with 5-10% of cases of infertility, but it is the sole cause or factor in only 2-3% of all infertility cases. Myomectomy is surgery done to remove myoma regardless of the methods. Objective. To assess impact of myomectomy on pregnancy rate and associated factors among reproductive age women who had myomectomy at St. Paul’s Hospital Millennium Medical College, in Addis Ababa. Methodology. Hospital-based retrospective cross-sectional study was conducted to determine pregnancy rate after myomectomy and its associated factors. Patients who had myomectomy in SPHMMC from September 2012 to September 2017 were enrolled. Information was retrieved from hospital records and phone interviews with the patients. The strength of statistical association was measured by adjusted odds ratios and 95% confidence intervals. Statistical significance was declared at p value 35 years were 0.31 times less likely to get pregnant after surgery than those ages 20-25 years [AOR=0.31 (95% CI: 0.29-0.54)]. People with no infertility before surgery were 1.19 times more likely to be pregnant after surgery than those with unexplained infertility before the surgery [AOR=1.19 (95% CI: 1.06-1.57)]. People with two uterine incisions were 0.06 times less likely [AOR=0.06 (95% CI: 0.043-0.51)] while those with three or more than three incisions were 0.02 times less likely [AOR=0.02 (95% CI: 0.002-0.22)] to get pregnant compared with those with one incision on uterine wall. Conclusion. Age, number of incision, and infertility before surgery were significantly associated with rate of pregnancy after myomectomy.
