Eight years with the same IUD.

Abstract

The purpose of this study was to determine the efficacy of the TCu380A (GYNET 380 IUD) in long-term users for periods of > 5 years and to obtain the incidence of Actinomyces as related to length of use and reasons for removal. The report is a retrospective descriptive study of all the clinical cases (n = 370 patients) at the Municipal Family Planning Centre-SERGAS A Coruña, Spain, of women who had a TCu380A IUD inserted during the period 1988-1989 with a September 1997 cutoff date for data analysis. A total of 271 (73.5%) patients had been using the TCu380A IUD for > 5 years with 100% efficacy. The accumulated incidence of Actinomyces was 5.9% (CI 95%: 3.8-8.9). The highest incidence was found between the second and third year of use. There was no increase in the incidence of Actinomyces after 5 years of use. The most common reason for removal of the IUD was the duration of use of 8 years with the same device (32.3%).
