بررسی پیامد بستن لوله‌های رحمی به‌روش غیرجراحی با قرص کیناکرین: کارآزمایی بالینی

Background: Over the last 35 years, quinacrine has been used to sterilize more than 150,000 women in 40 countries, first in the form of slurry and now in the form of cylindrical pellets. Some studies confirmed the tubal occlusion by hysterosalpyngo-graphy, but this method increases the chance of failure. Only a few studies on tubal occlusion have used transvaginal sonography for confirmation, and there were some doubts about the effect of quinacrine on the endometrium. We performed this study to evaluate the tubal scar and endometrial pattern by ultrasound and to determine the feasibility, acceptance, and side effects of quinacrine sterilization (QS) in Iranian womenMethods: This prospective clinical trial was done at the Vali-e-Asr Reproductive Health Research Center of the Tehran University of Medical Sciences between April 2005 and July 2006. One hundred sexually active women ranging from 30 to 47 years of age, who had at least two children above two years old, requesting sterilization, were sterilized by this method. By the end of menstrual bleeding, seven pellets, each containing 36mg quinacrine, were inserted in the uterine fundal area via the cervical canal. The procedure was repeated one month later. Three cycles after the first step, transvaginal sonography was performed to visualize the tubal scar and determine the endometrial pattern. Patients were followed at one and three years after initiation of the procedure. Results: All women were satisfied with the procedure. There were no side effects. No pregnancies had occurred, nor were there endometrial thickness abnormalities. Scar formation was visible in the tubes. Conclusion: Quinacrine sterilization is a useful method for women and can be recommended to family planning services as an ambulatory procedure due to its efficacy, simplicity, acceptance and cost effectiveness.
