Background: During pregnancy, asymptomatic bacteriuria is associated with different complications such as pyelonephritis and preterm birth. Pregnancy changes pave the way for the growth and multiplication of pathogenic factors. This study was aimed at exploring the frequency of asymptomatic bacteriuria among pregnant women who attended Boo–Ali Hospital, a teaching center of Islamic Azad University in Tehran. Materials and Methods: This cross-sectional study was performed on 123 pregnant women without urinary symptoms who attended Boo–Ali Hospital from March 2013 to September 2014. Demographic information of the patients including age, gestational age at the time of experiment and parity were recorded. An amount of middle part of urine (20cc) was collected in an appropriate sterile container. Urine samples were examined for WBC, RBC and bacteria. Other parts of the samples were cultivated for urine culture (U/C). Results: Two (1.6%) women had significant bacteriuria (≥105/ml). Pyuria, bacteriuria and hematuria were seen in 49(39.8), 7 (5.6%) and 8 (6.5%) women, respectively. There was a significant association between positive U/C and pyuria (P=0.003). However, positive U/C showed no significance association between bacteriuria and hematuria (P>0.05). Conclusion: Regarding the low frequency of asymptomatic bacteriuria (less than 2%) in the investigated population, the administration of U/C does not seem logical for all pregnant women. Hence, U/C is recommended for those with significant pyuria in their urinalyses. [GMJ.2015;4(4):159-63]
