Unilateral renal cystic disease (URCD) is characterized by replacement of most of one kidney by multiple cysts scattered diffusely throughout the parenchyma without the formation of a distinct, encapsulated renal mass. There are no cysts in the opposite kidney or liver. The condition is nonfamilial and does not cause renal functional impairment. We describe the clinical and radiologic findings in two patients with URCD and discuss how the disorder usually can be distinguished from other renal cystic diseases using CT. Absence of a family history of renal cystic disease and the normality of the other kidney help distinguish URCD from autosomal dominant polycystic kidney disease. The diffuse nature of the cysts in URCD and the absence of a distinct encapsulated renal mass help distinguish URCD from cystic renal neoplasms.
单侧肾囊性疾病（URCD）的特征是一侧肾脏的大部分被多个囊肿弥漫性地散布于整个实质所取代，未形成明显的、有包膜的肾肿块。对侧肾脏或肝脏无囊肿。该疾病为非家族性，不引起肾功能损害。我们描述了两名URCD患者的临床和影像学表现，并讨论了如何使用CT将该疾病与其他肾囊性疾病区分开来。无肾囊性疾病家族史以及对侧肾脏正常有助于将URCD与常染色体显性多囊肾病区分开来。URCD中囊肿的弥漫性以及无明显的有包膜肾肿块有助于将URCD与肾囊性肿瘤区分开来。
