肾周脂肪囊厚度在脂肪肝诊断中的应用价值

目的:探讨肾周脂肪囊厚度在脂肪肝诊断中的价值.方法:收集正常组与轻度、中重度脂肪肝组研究对象各30例, 超声测量双肾长轴切面下极与短轴切面肾周脂肪囊最厚处厚度.结果:肾周脂肪囊厚度在正常组与轻度、中重度脂肪肝组之间的差异存在显著意义(P <0.05), 而在轻度与中重度脂肪肝组之间的差异无显著意义(P >0.05); 1.25、0.65、1.05、0.55 cm作为超声诊断脂肪肝时右肾长轴下极与短轴肾周以及左肾长轴下极与短轴肾周脂肪囊厚度的临界值, 其灵敏度分别为72.7%、75.0%、72.7%、77.3%, 特异度分别为93.7%、87.5%、93.7%、87.5%.结论:肾周脂肪囊厚度可作为脂肪肝超声诊断的参考指标.

Value of fatty renal capsule thickness in diagnosis of fatty liver disease

AIM: To explore the clinic value of fatty renal capsule thickness in diagnosis of fatty liver disease. METHODS: Thirty cases with mild and or with moderate to severe degree of fatty liver were collected, and their fatty renal capsule thickness was measured. RESULTS: The fatty renal capsule thickness had significant differences between the normal group and mild, moderate to severe degree groups (P < 0.05), and had no differences between the mild and moderate to severe degree groups (P > 0.05). If 1.25, 0.65, 1.05, 0.55 cm were used as the critical value of the fatty renal capsule thickness for ultrasonic diagnosis of fatty liver at the long axis inferior pole, short axis surround of right kidney and left kidney, the sensitivities were 72.7%, 75.0%, 72.7% and 77.3% respectively, the specificities were 93.7%, 87.5%, 93.7% and 87.5% respectively. CONCLUSION: The fatty renal capsule thickness can be used as the reference index for the ultrasonic diagnosis of fatty liver disease.
