摘要
目的分析输尿管息肉的影像学表现,提高对输尿管息肉的诊断水平。资料与方法回顾性分析经手术病理证实的5例单纯输尿管息肉的影像学资料(X线、CT、MRI)。5例患者均行静脉肾盂造影,3例行逆行肾盂造影,2例行CT平扫和增强,2例行MR平扫。结果4例静脉肾盂造影发现病变,表现为管腔内边缘光滑的充盈缺损,1例病变侧肾脏输尿管未显影。3例逆行肾盂造影发现病变。2例CT检查发现增强后期扩张输尿管内低密度充盈缺损。2例MR平扫T2WI发现高信号管腔内低信号充盈缺损。结论输尿管息肉的影像学表现具有一定特征性。X线检查是输尿管息肉首选方法,CT、MRI可作为辅助诊断手段,对碘过敏及肾功能不良等不能使用碘对比剂的患者,首选MRI。
Objective To analyze the characteristic radiographic appearances of ureteral polyps and improve the accuracy of diagnosis. Materials and Methods The X-ray, CT and MR. data of 5 patients with ureteral polyp confirmed by surgery and pathology were retrospectively analyzed. Excretory urography were performed in all 5 cases, retrograde ureterography were performed in 3 cases, plain and contrast CT were performed in 2 cases and MRI were performed in 2 cases, Results There were hydronephrosis and a filling defects at the ureter by excretory urogram in 4 cases, one effect-side of another patients was not displayed. Lesions were found on retrograde ureterography in 3 cases, hypodensity filling detects were shown at the later enhancenrent on CT in dilated ureter of 2 cases. Low signal filling defects were shown on T2WI in 2 cases. Conclusion The radiographic appearances of ureteral polyps are characteristics. X-ray is the first choice method, and CT or MRI is subordinate, MRI should be taken as first choice for the allergic and renal disorder patients.
