The ultrasonographic features of multicystic renal dysplasia in 15 patients (14 children, 1 adult) are described with emphasis on differentiating this condition from hydronephrosis. The most useful ultrasonographic criteria for identifying multicystic kidney include: (a) the presence of interfaces between cysts (accurate in 100% of cases); (b) nonmedial location of the largest cyst (100%); (c) absence of an identifiable renal sinus (100%); (d) multiplicity of oval or round cysts that do not communicate (93%); and (e) absence of parenchymal tissue (73%). The role and usefulness of radionuclide renal scanning are also discussed. Ultrasonography followed by nuclear scintigraphy appears to be a logical diagnostic sequence in the evaluation of neonates with flank masses. Excretory urography is of value in assessing the status of the uninvolved kidney.
本文描述了15例（14例儿童，1例成人）多囊性肾发育不良的超声特征，重点是将这种情况与肾积水相鉴别。识别多囊肾最有用的超声标准包括：（a）囊肿之间存在界面（100%的病例准确）；（b）最大囊肿位于非内侧（100%）；（c）无可识别的肾窦（100%）；（d）多个椭圆形或圆形囊肿不连通（93%）；（e）无实质组织（73%）。还讨论了放射性核素肾扫描的作用和实用性。在评估有侧腹肿块的新生儿时，超声检查后进行核闪烁扫描似乎是一种合理的诊断顺序。排泄性尿路造影在评估未受累肾脏的状况方面具有价值。
