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。
