输尿管下段息肉的超声诊断价值

目的探讨超声诊断输尿管下段息肉的临床应用价值。方法对12例经输尿管镜或膀胱镜检查、病理检查证实为输尿管下段息肉（其中男性8例,女性4例,年龄17～60岁,平均年龄32.6岁;病程1个月～4年。左侧9例,右侧3例,合并输尿管结石4例,膀胱结石2例,肾结石1例,息肉自输尿管口部分脱入膀胱4例,随输尿管喷尿节律性脱入膀胱2例）的患者超声及临床资料进行回顾分析。结果超声对输尿管下段息肉的诊断符合率为58.3%（7/12）。误诊为输尿管癌3例,膀胱肿瘤2例,误诊率为41.7%（5/12）。其中合并输尿管结石4例,膀胱结石2例,肾结石1例。病理诊断为炎性增生性息肉9例,纤维性息肉3例。结论超声是输尿管下段息肉的首选筛查方法,对合并阴性结石、逆行造影困难、碘过敏者更具有价值。

Ultrasonic diagnosis of low segment ureteral polyp

Objective To study the clinical value of ultrasonic diagnosis for low segment ureteral polyp. Methods The ultrasonic and clinical data were analyzed retrospectively in 12 cases(male 8 cases,female 4 cases,aged 17 to 60 years,mean age 32.6 years;duration of illness 1 month to 4 years. Left focus 9 cases,right 3 cases,combined with ureter stone 4 cases,bladder calculus 2 cases,kidnery stone 1 case) confirmed as ureteral polyp in low segment by cystoscopy/or ureteralscopy,operations and pathologyical examination. Results The diagnostic coincidence rate was 58.3 %(7/12) of ultrasonic approach in low segment ureteral polyp. Three cases were misdiagnosed as ureteral carcinoma and two cases as tumor of urinary bladder,thus the misdiagnostic rate was 41.7 %(5/12). Of all cases there were 4 cases complicated with ureteral calculi,two cases with bladder stone and 1 case with renal stone. In pathological examination 9 cases of inflammatory hyperplastic polyp and 3 of fibroepithelial polyp were found. Conclusion Ultrasonic approach is the first choice for diagnosis low segment ureteral polyp,and it is more valuable in patients complicated with X-ray negative stone,difficult for retrograde urethrography and allergy to iodine.
