This paper describes angiographic and ultrasonic findings in three patients with proven infected renal cyst. The clinical picture was that of inflammatory renal disease. B-mode ultrasonography showed the characteristic features of renal cyst; however, this technique cannot differentiate between infected and simple cysts. Selective renal angiography demonstrated the following, enabling differentiation from simple renal cyst; hypervascular rim, irregular inflammatory vessels, indistinct interface between cyst and adjacent parenchyma, and prominent capsular branches. Since percutaneous puncture of an infected renal cyst or abscess carries risk of infectious complications, angiography appears justified only for those patients with fever and flank pain who have cystic lesions in the kidney confirmed by echography.
本文描述了3例经证实为感染性肾囊肿患者的血管造影和超声检查结果。临床表现为炎性肾病。B型超声显示了肾囊肿的特征性表现；然而，该技术无法区分感染性囊肿和单纯性囊肿。选择性肾血管造影显示出以下情况，有助于与单纯性肾囊肿相鉴别：血管丰富的边缘、不规则的炎性血管、囊肿与相邻肾实质之间界限不清以及明显的包膜分支。由于经皮穿刺感染性肾囊肿或脓肿有发生感染性并发症的风险，血管造影仅适用于那些经超声证实肾脏有囊性病变、伴有发热和侧腹痛的患者。
