结石

Methods An retrospective analysis on 54 failure cases of ureterolithiasis treated with URSL was made.

回顾54例经URSL治疗输尿管结石失败的病例（男38例，女16例），对其全部影像学资料进行分析。

Results With the low-dose scan, The sensitivity and accuracy rates of the detection of nephrolithiasis and ureterolithiasis on the low-dose scan were 100% and 98% respectively.

结果 所有低剂量扫描及后处理图像均获得成功，低剂量扫描检查结石的敏感性为100%，准确性为98%。

The sensitivity and accuracy rates of the detection of nephrolithiasis and ureterolithiasis on the low-dose scan were 100% and 97% respectively, and those of the detection of pelvicaliectasis and ureteral dilatation were all 100%.

与标准剂量扫描结果比较，低剂量扫描发现肾及输尿管结石的敏感性及准确率分别为100%、97%，发现肾积水及输尿管扩张的准确率100%。

Ultrasonography shows important value in the ureterolithiasis.

超声显像对输尿管结石的诊断具有重要价值。

The formatted nonenhanced spiral CT of ureter has potentil as an imaging for the ureterolithiasis with renal failure.

非增强螺旋CT输尿管重建可获得良好的输尿管成像，在输尿管结石并肾功能衰竭的诊断方面具有重要的临床价值。

Methods: By measuring the width of renal pelvis,compared with 98 normal persons, 93 cases with ureterolithiasis concurred with0 mm hydronephrosis, among them, there were 2 cases whose hydronephrosis involved both kidneys at the same time,have been observed and analyzed statistically.

98例正常人与93例(其中2例双肾同时发生积水)经X线体外震波碎石及临床确诊为输尿管结石的病例进行超声观察、登记、统计分析。

High accuracy for the detection of nephrolithiasis and ureterolithiasis is obtained and the radiation dose significantly decreased by using unenhanced 16-detector helical CT performed at a reduced tube current of 60mAs for the patients less than 90 kg.

对于体重＜90kg的病人，在16层螺旋CT，管电流为60mAS的低剂量平扫诊断肾及输尿管结石能够获得高的准确率，并且明显降低病人的放射剂量。

Methods Using three segmental region ultrasonography, 42 cases with ureterolithiasis without ipsilateral kidney hydrocele were confirmed by Xray, ESWL, urography, and combined treatment.

应用三分段区域扫查法，对42例经X线腹部平片、静脉尿路造影及体外震波碎石治疗或综合疗法排石证实的无同侧肾积水的输尿管结石进行检查。

Methods Sixty-five patients with suspected nephrolithiasis and ureterolithiasis were collected. Followed by standard-dose helical CT scans with 2-mm-thick section, 120kv, 160mAs, low-dose scan was carried out with the tube current reduced to 60mAs. All other technical parameters and anatomic coverage remained constant.

收集65例临床拟诊肾及输尿管结石病例，每一病例在常规标准剂量(120KV， 160mAs)扫描后再行低剂量扫描，在低剂量扫描中，管电流下降到60mAs，其余参数及扫描范围均保持不变。

Objective To explore the surgical technique and experience of laparoscopic ureterolithotomy.

目的 探讨腹腔镜治疗输尿管结石的技术要点和经验。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
