Association between diaphragm use and asymptomatic bacteriuria.

The prevalence of asymptomatic bacteriuria was assessed in women using different contraceptive methods. Three hundred and twenty women attending a family planning centre were studied, 80 in each of the following groups: diaphragms, intrauterine contraceptive devices (IUCDs), oral contraceptives (OCs) and no contraception. The numbers with asymptomatic bacteriuria in the 4 groups were as follows: diaphragm - 12 (all E coli); IUCD - 3 (E coli; P mirabilis; S saprophyticus); OC - 5 (all E coli); no contraception - 4 (3 E coli; 1 S saprophyticus). The prevalence of Gram-negative bacteriuria in women using diaphragms was significantly higher than for women in the other groups (chi 2 = 8.98; p less than 0.05). Factors such as parity, numbers of sexual partners and frequency of sexual intercourse had no apparent effect. The use of diaphragms may contribute to the risk of Gram-negative urinary tract infections in sexually active women.
