Methods: Clinical records of 112 pregnant women who presented UTI were reviewed, establishing the frequency of acute pyelonephritis (APN), infectious agent and antimicrobial susceptibility. Data were compared statistically with the records of 2001 and 1988 by calculating odds ratios. Results: The proportion of APN showed a decreasing.
