目的对先天性输尿管狭窄的影像学诊断方法进行比较分析。方法回顾性分析28例先天性输尿管狭窄患者的影像学诊断资料。结果 28例患者均采用静脉肾盂造影检查,显示输尿管狭窄段均位于肾盂输尿管移行处,狭窄段长度为0.6~2.0 cm,B超提示肾积水,CT扫描可以观察肾实质的动态增强曲线。结论先天性输尿管狭窄的诊断应该根据患者具体情况来选择1种、2种或2种以上影像学方法 ,多种检查方法联合运用可以提高疾病诊断的准确率。
Objective To compare the imaging diagnosis of congenital ureteral stricture. Methods The imaging diagnosis data of 28 patients with congenital ureteral stricture were retrospectively analyzed. Results All 28 patients underwent intravenous pyelography. The ureter stenosis was located in the ureteropelvic junction. The length of the stenosis was 0.6-2.0 cm. B-mode ultrasound showed hydronephrosis. The dynamic enhancement curve of renal parenchyma was observed by CT scan. Conclusion The diagnosis of congenital ureteral stricture should be based on the specific circumstances of patients to choose 1, 2 or 2 kinds of imaging methods, a combination of multiple inspection methods can improve the accuracy of disease diagnosis.
