Relationship between bacterial vaginosis and urinary tract infection

Background: Due to the high prevalence of urogenital infection and lack of knowledge about the relationship between bacterial vaginosis and urinary tract infection in the country, this study was conducted in patients referred to Shohada Hospital during the years 2001-2002 . Materials and Methods: This case-control study was carried out on 134 candidates. Individuals with signs of urinary tract infection and positive urine culture were considered as patients. Also, the individuals with negative urine culture that their age, coitus frequency, years of marriage and birth control methods were matched with the patients were considered as control group. Bacterial vaginosis in both groups was determined based on Amsel criteria. The results were analysed using t-test and x2 test. Then odds ratio and confidence intervals were calculated. Results: Sixty seven patients with urinary tract infection were compared with 67 normal individuals. Bacterial vaginosis was observed in 40.3% of the controls and in 62.7% of the case group (p<0.01, OR = 2.49). Characteristic discharge of bacterial vaginosis and pH over 4.5 was observed in 91% of the patients and positive Whiff test and clue cells were reported in 74% and 72% of the patients with bacterial vaginosis respectively. Conclusion: Individuals with urinary tract infection encountered bacterial vaginosis more than control group. We recommend further experimental studies for evaluation of the effectiveness of vaginitis treatment in prophylaxis of urinary tract infection and also, further attention to pregnant woman.
