超声持续观察对输尿管息肉和输尿管癌的鉴别诊断价值

Differential Diagnosis of Conventional Ultrasound in Ureteral Polyps and Ureteral Carcinoma via Continuous Observation

目的探讨常规超声持续观察对输尿管息肉和输尿管癌的鉴别诊断价值。资料与方法回顾性分析2015年6月—2022年6月陕西省人民医院98例病理证实为输尿管息肉患者的临床资料和常规超声表现,并以同期151例输尿管癌患者作为对照,比较两组临床资料特征,及常规超声检查中病变回声、血流、蠕动性等差异。结果两组患者输尿管病变是否蠕动、彩色多普勒血流分布、有无输尿管周围组织增厚、回声增高、有无患侧肾积水,差异有统计学意义(χ^(2)=197.50、138.89、26.97、36.13,P均<0.05);两组均以低回声为主[67(68.37)比114(75.50)],差异无统计学意义(χ^(2)=1.52,P>0.05)。输尿管息肉组67例见于上段输尿管,89例持续观察息肉常见蠕动,73例彩色血流多为病变中央型血流;输尿管癌组85例见于中下段输尿管,148例持续观察几乎未见蠕动,122例彩色血流多为病变周边型血流。结论输尿管息肉和输尿管癌好发位置及是否存在肾积水等临床表现存在一定差异,二维超声检查中持续观察输尿管息肉常见蠕动现象,可以为鉴别输尿管癌提供诊断参考。

Purpose To evaluate the differential diagnostic value of conventional ultrasound in the ureteral polyps and ureteral carcinoma via continuous observation.Materials and Methods The conventional ultrasound of patients with ureteral polyps and ureteral carcinoma treated in Shaanxi Provincial People’s Hospital were retrospectively analyzed from June 2015 to June 2022.According to the pathological results,all participants were divided into the ureteral polyp group(98 cases)and the ureteral carcinoma group(151 cases).All clinical and ultrasound data were recorded,and the differences of echo,blood flow and peristalsis were compared between the two groups.Results There were significant differences in ureteral peristalsis,color Doppler flow distribution,periureteral tissue thickening,increased echo,and hydronephrosis(χ^(2)=197.50,138.89,26.97,36.13,all P<0.05)between the two groups.Low echo was predominant in both groups[67(68.37)vs.114(75.50)],with no significant difference(χ^(2)=1.52,P>0.05).In the ureteral polyp group,67 cases were found in the upper ureter,89 cases were observed continuously with common peristalsis,and 73 cases with color blood flow were mostly central blood flow,while in the ureteral cancer group,85 cases were found in the middle and lower ureter,148 cases showed almost no peristalsis,and 122 cases with color blood flow were mostly peripheral blood flow.Conclusion There are some differences in clinical features such as the location as well as whether hydronephrosis between ureteral polyps and carcinoma.Peristalsis can provide the differential diagnosis for ureteral polyps and ureteral carcinoma via continuous observation.
