摘要
目的探讨腹部超声造影在鉴别低回声肾血管平滑肌脂肪瘤与肾透明细胞癌中的应用价值。方法67例经手术病理证实的肾肿块患者作为研究对象,均行腹部超声造影。分析所有患者的手术病理结果及超声造影表现,比较肾透明细胞癌与低回声肾血管平滑肌脂肪瘤患者的超声造影增强模式及超声造影诊断的准确性。结果67例肾肿块患者中,51例为肾透明细胞癌,16例为低回声肾血管平滑肌脂肪瘤。其中低回声肾血管平滑肌脂肪瘤内部均质,血管发育畸形,微血管较少,血流阻力高,且为厚壁血管,流速缓慢。超声造影显示,肾透明细胞癌以快进快退为主,占比47.06%;低回声肾血管平滑肌脂肪瘤以快进慢退为主,占比75.00%。肾透明细胞癌快进快退占比47.06%高于低回声肾血管平滑肌脂肪瘤的0,而快进慢退占比23.53%低于低回声肾血管平滑肌脂肪瘤的75.00%,差异有统计学意义(P<0.05)。两者同进同退、慢进快退和慢进慢退占比比较差异无统计学意义(P>0.05)。超声造影诊断肾透明细胞癌的准确率为92.16%,与低回声肾血管平滑肌脂肪瘤的93.75%比较,差异无统计学意义(P>0.05)。结论腹部超声造影在鉴别低回声肾血管平滑肌脂肪瘤与肾透明细胞癌中具有重要意义,可为临床治疗提供依据。
Objective To discuss the practival value of abdominal contrast enhanced ultrasound in distinguishing hypoechoic renal angiomyolipoma from renal clear cell carcinoma.Methods There were 67 patients with renal masses confirmed by surgery and pathology as study subjects,and all underwent abdominal contrast enhanced ultrasound.The pathological results and the performance of contrast-enhanced ultrasound in all patients were analyzed,and the accuracy of enhanced ultrasound mode and contrast-enhanced ultrasound in patients with renal clear cell carcinoma and hypoechoic renal angiomyolipoma was compared.Results Among 67 patients with renal masses,51 were renal clear cell carcinoma,and 16 were hypoechoic renal angiomyolipoma.Among them,the hypoechoic renal angiomyolipoma is homogeneous,with malformed vascular development,fewer microvessels,high blood flow resistance,thick-walled blood vessels,and slow flow rate.Contrast-enhanced ultrasound showed that renal clear cell carcinoma was predominantly fast forward and fast retreat,accounting for 47.06%;hypoechoic renal angiomyolipoma was predominantly fast forward and slow retreating,accounting for 75.00%.The proportion of fast-forward and fast-retreat renal clear cell carcinoma was 47.06%higher than 0 of hypoechoic renal angiomyolipoma,while the proportion of fast-forward and slow-retreat 23.53%was lower than 75.00%of hypoechoic renal angiomyolipoma.The difference was statistically significant(P<0.05).There was no statistically significant difference in the proportion of advance and retreat together,slow forward and fast retreat and slow forward and slow retreat(P>0.05).The accuracy of contrast-enhanced ultrasound in diagnosing renal clear cell carcinoma was 92.16%,which had no statistically significant different compared with 93.75%of hypoechoic renal angiomyolipoma(P>0.05).Conclusion Abdominal contrast enhanced ultrasound has great significance in distinguishing hypoechoic renal angiomyolipoma from renal clear cell carcinoma,which can provide a basis for clinical treatment.
