先天性肾盂输尿管交界部梗阻的影像学诊断方法比较

Evaluation of Imaging methods in the diagnosis of congenital ureteropelvic junction obstruction

为提高对先天性肾盂输尿管交界部梗阻(UPJO)的诊断,评价影像诊断的价值,对80例先天性UPJO的病人的影像学检查资料进行回顾性比较分析,结果表明所有病人均作了静脉肾盂造影及B超检查;50例行逆行肾盂输尿管造影;20例曾行腹部CT检查;利尿性肾核素检查25例。75例外科手术治疗。先天性UPJO可分为两大类,动力性和机械性梗阻。动力性梗阻在临床及影像学表现上无特异性,机械性梗阻有其特征性的影像学表现。因此认为尿路造影诊断可以明确诊断,优于CT、B超、同位素的诊断价值。

To impreve the diagnosis of congenatal ureteropelvic junction obstruction(UPJO) and evaluate the value of imaging methods, 80 cases of congenital UPJO were analyzed retrospectively. The imaging methods done include IVP and B-ultrasonography, retrogradepyelography. CT or other examination. 75 cases underwent surgical treatment, the remains treated with medicine. The data shows the congenital UPJO can be classfied into two groups, motor and mechanical obstruction. The most of mechanical UPJO have special radiological manifestations, but the motor UPJO hasn't. It suggested the causes of conginatal UPJ obstruction is very complex and contrast urography not only give diagnosis but also provide useful information.
