腔内三维超声在诊断输尿管下段疾病中的临床应用

目的 评价腔内三维超声成像检查在输尿管下段病变中的诊断价值。方法 对42例输尿管下段病变患者先进行腔内二维超声检查，并进行腔内三维超声重建，对两者图像进行描述，并进行对比分析。结果 经腔内三雏超声成像后，可以更清晰地了解病变与输尿管管壁的关系、病变与输尿管管腔，病变与膀胱输尿管开口、病变与输尿管开口旁的膀胱壁的空间关系，腔内三维超声病变检出率为88．10％，二维超声检出率为74．13％，三雏超声检出率明显高于二维超声（P〈0.01）。结论 实际应用中发现腔内三雏成像可以提供较二雏图像更丰富的信息，能够更有效地发现二雏超声无法检出的病变。

The value of endoluminal three - dimensional ultrasound in diagnosis of lower ureter disease

Objective To evaluate the value of endoluminal three- dimensional ultrasound in diagnosis of lower ureter disease. Method 42 patients with lower ureter disease underwent endoluminal two- dimensional ultrasound and endoluminal three- dimensional ultrasound examinations separately. Their results were compared. Results Endoluminal three- dimensional ultrasound compared with endoluminal two- dimensional ultrasound denoted the spatial relations, the pathology and the ureter pipe wall relations, the pathology and the ureter tube cavity, the pathology and the lower ureter aperture, the pathology and the bladder wall in the side of the lower ureter aperture. Detection rate of disease with endoluminal three- dimensional ultrasound was increased significantly compared to that with two- dimensional ultrasound ( P<0.01). Conclusion Endoluminal three dimensional ultrasound can provide more information on disease and can detect focus of infection easily, so it has extensive prospect on diagnoses of the lower ureter disease.
