Routine ultrasonographic detection of renal tract dilatations in pregnant women is used to define a high risk population for urinary tract infections. In a first group of 96 patients with symptomatic urinary tract infection, 34% of the cases of uncomplicated infection were accompanied by ultrasonographic abnormalities, while 73% of cases of pyelonephritis presented such signs. Antibody coated bacteria were only found in 12% of uncomplicated urinary tract infections and in 30% of cases of pyelonephritis. In a second group of 273 patients, routine ultrasonography revealed abnormalities in 11.5% of cases. 7.5% of patients had dilatations of the upper renal tract, 2% had renal stones and 2% had occult renal malformations. Dilatations of the upper renal tract were associated with asymptomatic urinary tract infections in 30% of cases. Screening for upper renal tract dilatations is recommended between the 17th and 20th weeks of pregnancy. The presence of such lesions constitutes a risk factor for urinary tract infection and appropriate prophylactic treatment should be prescribed.
孕期常规超声检查泌尿系统扩张用于确定尿路感染的高危人群。在第一组96例有症状的尿路感染患者中，34%的单纯性感染病例伴有超声异常，而73%的肾盂肾炎病例有此类体征。仅12%的单纯性尿路感染病例和30%的肾盂肾炎病例发现有抗体包裹细菌。在第二组273例患者中，常规超声检查发现11.5%的病例有异常。7.5%的患者有上尿路扩张，2%有肾结石，2%有隐匿性肾畸形。30%的上尿路扩张病例与无症状尿路感染有关。建议在妊娠第17至20周期间筛查上尿路扩张。此类病变的存在构成尿路感染的危险因素，应给予适当的预防性治疗。
