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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
