目的提高原发性输尿管癌的诊断水平。方法分析35例输尿管癌的临床资料,比较各种检查方法,总结诊断经验。结果35例均行B超检查,10例提示输尿管占位性病变;30例行静脉尿路造影(IVU)检查,7例提示输尿管病变;30例行膀胱镜检查,发现输尿管口有新生物脱出2例;23例行逆行肾盂输尿管造影检查,18例提示输尿管病变;35例行尿找脱落细胞检查,3例发现肿瘤细胞;23例行CT检查,15例提示输尿管病变;9例行磁共振尿路成像(MRU)检查,9例均提示输尿管病变;11例行输尿管镜检查,10例病理证实为输尿管癌。全组均行手术,术后病理检查均证实为移行细胞癌。结论联合应用多种检查方法可明显提高术前确诊率,B超、IVU是诊断原发性输尿管癌的基本方法,输尿管镜检查+病理活检是确诊输尿管肿瘤的重要手段。
Objective To improve the diagnosis of primary ureteral cancer. Methods The clinical data of 35 cases of ureteral carcinoma were analyzed, and various methods of examination were compared to summarize the experience of diagnosis. Results All the 35 cases underwent B-mode ultrasound examination, 10 cases showed ureteral space-occupying lesions, 30 cases underwent intravenous urography (IVU), 7 cases showed ureteral lesions, 30 cases underwent cystoscopy and found that there was a new biopsy 23 cases underwent retrograde pyelography; 18 cases showed ureteral lesions; 35 cases underwent exfoliative cells examination in urine; 3 cases found tumor cells; 23 cases underwent CT examination; 15 cases showed ureteral lesions; 9 cases underwent magnetic resonance Urinary tract imaging (MRU) examination, 9 cases were prompted ureteral lesions; 11 cases of ureteroscopy, 10 cases of pathological confirmed as ureteral cancer. All patients underwent surgery, postoperative pathology confirmed as transitional cell carcinoma. Conclusion Combined application of multiple examination methods can significantly improve the preoperative diagnosis, B ultrasound, IVU is the basic method of diagnosis of primary ureteral cancer, ureteroscopy + biopsy is an important means of diagnosis of ureteral tumors.
