title: [Prevalence of urinary tract infection in hospitalized patients with preterm labor].
abstract: OBJECTIVE
  To determine the prevalence of urinary tract infection (UTI) in patients with preterm labor.
  
  
  METHODS
  A prospective, observational, descriptive study, with a sample of 272 patients who were hospitalized in the Hospital de la Mujer at Culiacan, Sinaloa that presented symptoms of preterm labor. Age body mass index (BMI), parity, education, weeks of gestation, mode of delivery, history of preterm delivery and UTI were assessed.
  
  
  RESULTS
  Of the 272 patients with threatened preterm delivery, 97 (35.6%) had positive urine culture and of these patients, 32 (32.9%) had preterm labor. Association between urinary tract infection and patients with a hemoglobin (Hb) less than 11 g/dL OR: 2.66 95% CI (1.55-4.55), p 0.0003. Was isolated E. coli in 72 (74.4%) patients, Proteus in 9 (9.2%) patients. It was found that 42% of E. coli strains were resistant to ampicillin and 38.4% to ciprofloxacin.
  
  
  CONCLUSIONS
  The prevalence of UTI is higher than the national prevalence.
