We correlated contrast-enhanced cross-sectional imaging and outcomes to assess the reproducibility of ultrasonographic criteria for renal minimally complex (MC) cysts. From 2003 to 2015, 143 cysts were described as complex or MC by ultrasound (US). After exclusions, 98 US studies were retrospectively evaluated and compared with computed tomography (CT)/magnetic resonance imaging (MRI). At sonography, 51 were MC cysts and 47 were complexes according to two independent observers. Inter-observer agreement for US was 0.704 and 0.745 for CT/MRI. Of 51 cysts classified as MC by US, 38 were Bosniak I/II and 6 were Bosniak IIF by CT/MRI. In 7, there were no cross-sectional images; however, they were stable for at least 2 y. Of 47 complex cysts, 9 were Bosniak II, 22 Bosniak IIF, 8 Bosniak III and 8 Bosniak IV. No Bosniak III/IV cysts by CT/MRI were classified as MC by US. Our results indicate that US offers reproducible criteria for MC cysts and may be used alone for these lesions.
我们将对比增强横断面成像与结果相关联，以评估肾微复杂（MC）囊肿超声标准的可重复性。2003年至2015年期间，143个囊肿经超声（US）检查被描述为复杂或微复杂。排除相关因素后，对98项超声研究进行回顾性评估，并与计算机断层扫描（CT）/磁共振成像（MRI）进行比较。在超声检查中，根据两名独立观察者的判断，51个为MC囊肿，47个为复杂囊肿。超声检查的观察者间一致性为0.704，CT/MRI检查的观察者间一致性为0.745。在超声检查分类为MC的51个囊肿中，CT/MRI检查显示38个为博斯尼亚克I/II级，6个为博斯尼亚克IIF级。7个囊肿没有横断面图像；然而，它们至少稳定2年。在47个复杂囊肿中，9个为博斯尼亚克II级，22个为博斯尼亚克IIF级，8个为博斯尼亚克III级，8个为博斯尼亚克IV级。CT/MRI检查为博斯尼亚克III/IV级的囊肿，超声检查均未分类为MC囊肿。我们的结果表明，超声为MC囊肿提供了可重复的标准，可单独用于这些病变的诊断。
