碎石

Ureteroscopic lithotripsy manipulation is believed to be a safe and effective method for the treatment of ureterolith street with complicating acute renal failure.

认为输尿管镜弹道碎石术是治疗输尿管石街并发急性肾功能衰竭的一种安全有效的方法。

To investigate the effects on the management of ureterolith street with ureteroscopic lithotripsy.

目的 探讨应用输尿管镜弹道碎石术治疗输尿管石街并发急性肾功能衰竭的临床效果。

Methods 5 cases of ureterolith street with complicating acute renal failure were treated by emergency ureteroscopic lithotripsy and double-J tubes indwelling.

对5例输尿管石街并发急性肾功能衰竭采用急诊输尿管镜弹道碎石术治疗的患者的临床资料进行回顾性分析。

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。

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。

Results The stone was completely expelled in 18 cases with slight complications (hematuria 1～2 days) after 1～2 more times ESWL ,6 cases failed and went to ureterolithotomy.

结果 18例粘连性结石经球囊导管扩张后剥离粘连，结合体外冲击波碎石1～2次后粉碎排净，并发症轻微，只有血尿1～2d，自行消失。6例失败改切开取石。

Results:17 cases were abandoned because of stone migration to renal pelvis,8 cases were stopped owing to the tortuosity or the narrowness of ureters,5 cases failed because operation area was not clear,6 cases were managed by open ureterolithotomy because of ureteral perforation.

结果：17例手术中结石移位进入肾盂，无法碎石；8例因输尿管走行迂曲或输尿管狭窄置镜未成功；5例因局部出血或引流不畅导致视野不清终止手术；6例因输尿管穿孔而改开放手术。

Methods Hydronephrosis with negative evidence of ureteral calculi were shown on intravenous urogram in 73 patients. Unenhanced spiral CT scan (2 mm) and urinary ultrasonography were required.

73例排泄性尿路造影(intravenous urogram， IVU)显示肾盂积水但未见结石的患者，均进行B超和螺旋CT平扫(2mm)，采用输尿管镜／钬激光碎石治疗。

Vicissitudinary changes of temperature and humidity can easily induce shrinkage cracks,and sometimes these cracks reflect to surface of asphalt pavement.

但从多年的实际应用来看，这种水泥稳定碎石在温度或湿度交替变化时容易发生收缩裂缝和干缩裂缝，当沥青面层较薄时，这些裂缝会反射到面层，形成反射裂缝。

This machine is used to crush the rock up for road building.

这台机器用于碎石，以供筑路之需。
