Urinary infection in pregnancy: analysis of diagnostic methods and treatment - Revista Brasileira de Ginecologia e Obstetrícia
Revista Brasileira de Ginecologia e Obstetrícia. 2002;24(7):471-477
Purpose: to assess the diagnostic and therapeutic aspects and the complications of symptomatic urinary tract infections (UTI) during pregnancy of patients who were hospitalized. Methods: a total of 136 pregnant women with a clinical diagnosis of pyelonephritis were studied. The studied parameters were: age and parity of patients, gestational age of diagnosis, epidemiologic aspects, laboratory evaluation for UTI, treatment and clinic evolution, prophylaxis and complications. Results: pyelonephritis was diagnosed at the same proportions at all gestational ages. The incidence of UTI was higher among primigravidae. Only 29.3% of the pregnant women had a previous history of UTI; 57.0% were anemic and 93.0% had altered urinalysis. Escherichia coli was the most prevalent uropathogen (75.8% of cases), with low percentages of sensitivity to ampicillin (60.6%) and high percentages of sensitivity to cefuroxime (95,5%). The highest rate of clinical improvement was obtained for the pregnant women treated with cefuroxime (95.7%). Prophylaxis was needed in 11.0% of the patients. Preterm labor occurred in 33.3% of the pregnant women who delivered in our service and preterm delivery occurred in 18.9%. Conclusions: the present results support the need for an early diagnosis and effective treatment of UTI in pregnant women in order to prevent the frequent occurrence of perinatal complications such as premature labor and delivery. We emphasize the need of a periodical evaluation of the pattern of sensitivity of the etiologic agents to the antimicrobials allowed for use during pregnancy, with cefuroxime being adopted as the antibiotic of choice for the treatment of UTI during pregnancy.
