Urinary tract infection is a common pregnancy complication. Asymptomatic bacteriuria (AB) can trigger the development of serious complications affecting both the mother and the fetus.
Determine the frequency of AB among pregnant women attending to antenatal care at the family medicine clinic number 1 of the Instituto Mexicano del Seguro Social, located in Ciudad Obregón, Sonora.
A longitudinal study was carried out from September to December 2004. Seventy-two 72 pregnant women with gestational age of 24 weeks or less were followed up during four months. All pregnant women were selected by a non-probabilistic method. Every patient had a monthly urine culture during the follow up period.
Among the 72 pregnant women, 16.7% developed symptomatic urinary infections during the follow-up and 25% had at least one positive urine culture without urinary symptoms, being classified as AB, thus receiving treatment. Frequency of positive urine cultures was common at first and fourth months of follow-up.
Urine culture is an important component of prenatal care, and helps in identifying a significant number of urinary tract infections that would go otherwise undetected.
尿路感染是一种常见的妊娠并发症。无症状菌尿（AB）可引发影响母亲和胎儿的严重并发症。
确定在位于索诺拉州奥布雷贡市的墨西哥社会保障局第一家庭医学诊所接受产前护理的孕妇中AB的发生率。
于2004年9月至12月进行了一项纵向研究。对72名孕周为24周或更小的孕妇进行了四个月的随访。所有孕妇均通过非概率方法选取。在随访期间，每位患者每月进行一次尿培养。
在72名孕妇中，16.7%在随访期间出现有症状的尿路感染，25%至少有一次尿培养呈阳性但无尿路症状，被归类为AB，因此接受了治疗。尿培养阳性率在随访的第一个月和第四个月较为常见。
尿培养是产前护理的重要组成部分，并有助于识别大量否则会未被发现的尿路感染。
