The Prevalence and Bacteriology of Asymptomatic Bacteriuria among Antenatal Patients in Nnamdi Azikiwe University Teaching Hospital Nnewi; South Eastern Nigeria

ABSTRACT

Urinary tract infection in pregnancy leads to poor pregnancy outcome. Diagnosis and treatment of asymptomatic bacteriuria markedly improves pregnancy outcome as well as reduce the incidence of acute pyelonephritis. To determine the prevalence and bacteriology of asymptomatic bacteriuria among Antenatal patients in our centre; and to know if routine screening will be justifiable. This was a prospective study carried out between April and August 2008. Sample size was statistically determined.Women who consented were interviewed and mid stream urine samples were collected and processed in the microbiology laboratory; using standard microbiological methods. Out of 357 women studied; 65(18.21) had significant bacteriuria. was the commonest isolate (25.6); while was the least frequent isolate (3.66). Women in third trimester had the highest prevalence (25.68) while those in the first trimester had the least (15.79).Women that had only primary education had the highest prevalence (27.50) while those that had tertiary education had the least prevalence (21.10). The prevalence of significant asymptomatic bacteriuria among the women studied was high. Screening of all the pregnant women and treatment will reduce the incidence and complications of overt urinary tract infection in pregnancy among these women
