objective to study the ct diagnosis of ureteral calculus at the distal end of ureter.methods 82 cases of ureteral caculus were examined by ct scanning.all cases were proved by clinical therapeutic results.results ureteral calculuses were showed as high density image in ct scanning.the ct values of the ureteral calculuses less than 7.5mm in diameter were beyond 83hu.the detection rate by ct was 96.3%.in all the 82 cases,ureteral with calculuses were found dilated and 69 cases with nephrohydrosis.in 13 cases with no nephrohydrosis,caculuses less than 3.8 mm in diameter were found.conclusion ct is the most valuable way to diagnose ureteral calculus at the lower end of ureter.appropriate methods of ct scanning are essential.

目的 回顾性分析输尿管膀胱入口处结石的ct诊断结果，评价其ct检查的临床应用价值。方法分析82例输尿管膀胱入口处结石的ct检查结果，所有病例均经尿道排石证实。结果输尿管膀胱入口处结石具有特征性的ct表现，即圆形或枣核状钙化高密度影，结石直径＜7.5mm，ct值≥83hu，ct确诊率96.3%。82例均发现病侧输尿管增粗，69例发现病侧肾盂少量积水，肾盂未见积水的输尿管膀胱入口处结石13例，其结石直径＜3.8mm。结论 ct检查输尿管膀胱入口处结石具有准确、无创、直观等优点，是诊断输尿管膀胱入口处结石不可替代的检查方法。

RESULTS:① The demonstrating rate of intrahepatic bile duct calculus was 87.5% and that of other parts was 100%.② The rate of orientative diagnosis of choledocholithiasis was 94.7%, that of intrahepatic bile buct calculus was 75.0％ and that of other parts was

结果：①定位诊断：对肝内胆管结石梗阻部位显示率为87.5%，对其他梗阻部位显示率为100%；②定性诊断：术前诊断胆总管结石正确率为94.7%，肝内胆管结石正确率为75.0%，其他胆道梗阻正确率为90.9%～100%。

objective to discuss the nursing methods of acute postrenal renal calculus obstruction through ureteroscope.methods the preoperative and postorerative aborative nursing in 22 cases of patients with ureter calculus who were treated by emergency ureteroscope were analyzed retrospectively.results all patients became well and renal function was improved quickly after operation,after the timely treatment and nursing,none patients occured the serious complication.conclusion timely and right preoperative preparation,mental nursing and postoperative nursing were essential for the success of operation.

目的 讨论经尿道输尿管镜治疗急性肾后结石梗阻的护理方法。方法对22名患者进行急诊经尿道输尿管镜，治疗上尿路结石的术前、术后精心护理的回顾分析。结果所有患者顺利接受手术，术后患者全身状况、肾功能快速恢复，并发症得到及时治疗和护理，无一例发生严重并发症。结论及时准确的术前准备、心理护理、术后护理、是保证手术成功的重要保障。

Results Successful lithotripsy was achieved in 78 cases ,two cases failed because movement of calculus to pelvis renalis in one and no access to calculus site by ureteroscope due to ureterostenosis at inferior segment in the other .

结果 1例因结石上移至肾盂，1例因输尿管下段狭窄使输尿管镜无法到达结石部位手术失败，其余78例均碎石成功，术后当天肾绞痛缓解，碎石手术成功率和术后肾绞痛缓解率均为97.5%。
