摘要
目的:探讨采用低剂量螺旋CT及CT尿路造影(CTU)、后处理重建技术对输尿管小结石诊断的临床应用价值。材料与方法:对55例临床表现为剧烈腰腹痛可疑输尿管小结石的患者,行低剂量螺旋CT容积扫描,运用后处理技术取得CTU及二维、三维重建图像。结果:55例均行CTU及重建后处理,清晰显示输尿管全程,同时显示结石大小、形态、位置和输尿管扩张的程度及范围。结论:应用低剂量螺旋CT及重建技术,是目前诊断输尿管小结石最好的方法,对指导临床选择治疗具有重要作用。
Purpose： To evaluate the low dose radiationc linical value of diagnosing small ureteral with 16 slice spiral CT scan and CT urography（CTU）. Materials and Methods： 55cases with renal colic of suspected ureteral calculus were ex- amined with ultrasoniography, KUB and IVU. Results： 55 cases were found by unenhanced or enhanced CT. The location, size and morphology of calculi and ureter obstruction could be clearly demonstrated. Conclusion： Multi slice spiral CT low dose radiatione can diagnose ureteral calculi exactly, especially to small ureteral calculi in lower segment, moreover, CTU and 3D-reconstruction is of important value in diagnosing, therapy and observing secondary signs of ureteral calculus.
