Introduction: The aim of this study was to compare the frequency of asymptomatic bacteriuria in women who use intrauterine devices (IUDs) as a contraceptive method with subjects who use tubal ligation (TL).
Materials and Methods: A cohort study was conducted on women who were candidates for IUD insertion or TL (control). The patients were followed for 3 months, and urine cultures were assessed for bacteriuria at the end of the study.
Results: Overall, 131 women (mean age, 31.9 Â± 4.25 years) in the IUD group and 78 (mean age, 32.1 Â± 4.0years) in the control group were studied. The parity score was 2 or more in 72% of the women in the IUD group and in 74% of the controls. The average intercourse frequency was twice per week in 82% of IUD users and 80% of controls. Fifty-seven percent of the women in the IUD group and 55% of the women in the control group had graduated secondary school (high school). Asymptomatic bacteriuria was detected in 13 IUD users (9.9%) and in 1 woman (1.3%) in the control group (risk ratio = 7.74, confidence interval: 1.03 to 58.03; P = .019). The detected microorganism in the urine culture was Escherichia coli in 12 IUD users and in 1 patient in control group. Klebsiella was found in 1 IUD user.
Conclusion: Use of an IUD is a risk factor for urinary tract infection and should be considered, especially in women with recurrent urinary tract infections.
