We studied efficacy of using MR imaging (MRI) in differential diagnosis of serous and pyodestructive pyelonephritis in pregnant women. We performed MRI (MR tomograph Siemens Magnetom Symphony, Germany; 1.5 T, 20 mT/m) in 28 women with acute gestational pyelonephritis (pregnancy trimester II and III) to reject pyodestructive changes in the kidneys, paranephral fat, including cases with drained kidney. Three women were operated. The decision about operation was made basing on clinical, ultrasound, MRI pictures which confirmed the diagnosis of pyodestructive process. In the other cases MRI definitely described the state of the parenchyma and calyculopelvic renal system after drainage, rejected pyodestructive lesion, and, finally gave grounds for decision on conservative therapy which later proved effective. Thus, MRI is a method of choice in suspected pyodestructive gestational pyelonephritis, in ideal conditions it is a routine method of examination of pregnant women when it is necessary to get significant information on anatomofunctional status of the kidneys and urinary tract.
我们研究了磁共振成像（MRI）在鉴别诊断孕妇浆液性和脓性破坏性肾盂肾炎中的有效性。我们对28例急性妊娠期肾盂肾炎（妊娠中期和晚期）的女性进行了MRI检查（德国西门子Magnetom Symphony磁共振断层扫描仪；1.5T，20mT/m），以排除肾脏、肾旁脂肪的脓性破坏性改变，包括肾引流的病例。3名女性接受了手术。手术决策基于临床、超声和MRI图像，这些图像证实了脓性破坏性病变的诊断。在其他病例中，MRI明确描述了引流后肾实质和肾盂肾盏系统的状态，排除了脓性破坏性病变，最终为保守治疗决策提供了依据，而保守治疗后来证明是有效的。因此，MRI是疑似脓性破坏性妊娠期肾盂肾炎的首选检查方法，在理想情况下，当需要获取有关肾脏和尿路解剖功能状态的重要信息时，它是孕妇的常规检查方法。
