Computed tomographic (CT) findings of 17 pyonephrotic and 20 uninfected hydronephrotic kidneys were reviewed. Parameters evaluated included: renal pelvic wall thickness (none; grade 1, < or = 2 mm; grade 2, 3-5 mm; and grade 3, > 5 mm), renal pelvic contents, parenchymal, and perirenal findings. All patients underwent subsequent percutaneous nephrostomy within 1 week of CT. Common CT findings suggesting pyonephrosis include increased pelvic wall thickness and more severe perirenal fat changes than are seen in uninfected hydronephrosis. However, for any one patient, these findings are often not diagnostic. The presence of clinical signs of infection with hydronephrosis on CT is a more sensitive indicator of pyonephrosis than most CT findings.
回顾了17例脓肾和20例未感染肾积水患者的计算机断层扫描（CT）结果。评估的参数包括：肾盂壁厚度（无；1级，≤2mm；2级，3 - 5mm；3级，>5mm）、肾盂内容物、实质及肾周表现。所有患者在CT检查后1周内均接受了经皮肾造瘘术。提示脓肾的常见CT表现包括肾盂壁增厚以及肾周脂肪改变比未感染肾积水更严重。然而，对于任何一位患者，这些表现往往不能确诊。CT上肾积水伴有感染临床体征比大多数CT表现更能敏感地提示脓肾。
