Internal vaginal douching increases the incidence of vaginal infection among IUD users: a cross-sectional study

Background We compared the rate, type and severity of vulvovaginitis in women who are practicing internal vaginal douching (IVD) or not while using an intrauterine contraceptive device (IUCD). It is a cross-sectional study on 604 consecutive attendees of the outpatient clinics using IUCD for at least 6 months prior to recruitment. Eligible participants were divided into two groups: group 1 (302 women) performing IVD and group 2 (302 women) not practicing this habit (NIVD). The frequency of vaginal infections in IUCD users who perform IVD compared to women who were abstaining from this habit was our primary outcome. Results They are IUCD users who were practicing IVD more frequent history of vaginal infection (VI) compared with NIVD-IUCD users [260 (88.1%) versus 151(43.4%); respectively] ( P < 0.001). Current diagnosis of VI was significantly higher in IVD group (275; 91.05%) compared to NIVD group (115; 38.1%) ( P < 0.001). Bacterial vaginosis was the most common infection (287; 47.5%) followed by candida vulvovaginitis (278; 46.03%). Moreover, both types of infections were significantly more common in IVD. Conclusion The use of IUCD may not increase occurrence of vulvovaginitis, but IVD does increase vaginal infection rate either with or without IUCD use. When vaginal infection happens with IUCD, BV is the most common type of infection followed by Candida albicans .
