实时三维超声与二维超声诊断输尿管下段结石150例对比分析

目的：对比二维超声检查结果，评估实时三维超声成像技术诊断输尿管下段结石的应用价值。方法：分析输尿管下段结石病例150例共152个病变，均作二维超声及实时三维超声诊断，并以手术取石、碎石、药物排石后结果作为验证标准。结果：输尿管下段结石在合并肾盂积液情况下，两种方法之间无显著差别（P〉0．05）；当无肾盂积液情况下，两种方法有显著差异（P〈0．05），实时三维超声比二维超声确诊率高；总体上两种方法有显著差异（P〈0．05），实时三维超声比二维超声准确率要高，漏诊少。结论：经实时三维超声诊断输尿管下段结石比经二维超声准确率高，具有直观、立体感强的特点，应用容积存储效应，结合多切面选择，可协助疑难病例的诊断，对减少漏诊输尿管下段结石有实用价值。

Real-time Three-dimensional Ultrasound and Two-dimensional Ultrasound Diagnosis of 150 Cases of Lower Ureteral Stones Comparative Analysis

Objective： Contrast two-dimensional ultrasound examination results to assess the real-time three-dimensional ultrasound imaging diagnosis of lower ureteral stones application. Methods： Analysis of cases of lower ureteral stones 150 cases, are treated as two- dimensional ultrasound and real-time three-dimensional ultrasound diagnosis, X-ray urography, CT, surgery to take stone, gravel, drug row of results as the Standard. Results： Lower Ureteral calculi by real-time three-dimensional ultrasound-dimensional imaging rate of 90.7% （136/150）; the renal pelvis fluid in the consolidated cases, the two methods was no significant difference between them （P〉0.05）; when no renal pelvic fluid circumstances, the two methods were significantly dif/brent （P〈0.05）, real-time three- dimensional ultrasound diagnosis rate more than of two-dimensional ultrasound; overall significant difference between the two methods （P〈0.05）, real-time three-dimensional Ultrasound accuracy rate than the two-dimensional ultrasound is higher, fewer missed. Conclusion： The real-time three-dimensional ultrasound diagnosis of lower ureteral stones than being two-dimensional ultrasound with high accuracy, with an intuitive, three-dimensional sense of strong characteristics, application volume storage effects, combining more than one aspect of options to assist the diagnosis of difficult cases, to reduce the misdiagnosis of Lower Ureteral calculi practical value
