目的 :B型超声 (B超 )对小儿肾重复畸形 (重肾 )的诊断价值。方法 :本文回顾性对比分析了 39例(42个 )经病理证实的重肾的手术发现、B超声像表现。结果 :14例重度积水型重肾 ,B超对 10例作出诊断 ,2例提示性诊断 ,2例误诊为囊肿 ;16例轻～中度积水型重肾 ,B超对 15例作出诊断 1例误诊为肾积水伴输尿管扩张 ;9例发育不良型重肾 ,B超对 5例作出诊断 ,2例提示性诊断 ,2例漏诊 ;3例发育型重肾 ,B超仅对 1例作出诊断 ,2例漏诊。结论 :B超诊断积水型重肾 ,尤其重度积水型和发育不良型重肾的价值较高 ;而对发育型重肾 ,B超的诊断价值较低。
Objective: To evaluate the diagnostic value of ultrasound B (B ultrasound) in children with deformity of kidney (kidney weight). Methods: This retrospective analysis of 39 cases (42) of pathologically confirmed kidney weight found by surgery, B ultrasound imaging. Results: Fourteen cases of severe hydronephrosis, B-ultrasound diagnosis of 10 cases, 2 cases of suggestive diagnosis, 2 cases misdiagnosed as cysts; 16 cases of mild to moderate hydronephrosis, B-ultrasound diagnosis of 15 cases 1 case was misdiagnosed as hydronephrosis with ureteral dilatation; 9 cases of dysplastic kidney, B ultrasound diagnosis of 5 cases, 2 cases of prompt diagnosis, 2 cases of missed diagnosis; 3 cases of development of severe kidney, B-only in 1 case Make a diagnosis, 2 cases missed diagnosis. Conclusion: The diagnostic value of B-mode ultrasonography in diagnosis of severe hydronephrosis, especially in severe hydronephrosis and dysplastic kidney disease is high, while it is low in diagnosis of developing severe kidney and B-mode ultrasound.
