目的 对原发性输尿管肿瘤发病情况和诊断方法进行了讨论 ,并对本病手术方式进行了分析。方法 对临床上主要表现为全程肉眼血尿的 16例患者 ,进行术前检查 ,并经术后病理报告为移行细胞癌。结果术前检查结果分别为 :16例静脉尿路造影中 ,4例不显影 ,12例肾积水 ;膀胱镜检 14例中 ,3例输尿管口肿瘤 ;逆行肾盂造影 11例 ,5例插管受阻 ,6例输尿管狭窄 ;B超检查 6例 ,均示肾积水 ,其中输尿管肿瘤 6例 ,腹膜后肿块 1例 ;CT检查 3例 ,腹膜后肿块 1例 ,2例肾积水 ;尿脱落细胞检查 6例 ,2例查到肿瘤细胞。 16例均行手术治疗。术后病检 16例均示移行细胞癌。结论 认为对早期单发病例可行姑息性手术 ,对浸润性的高级期肿瘤应作输尿管全长切除术 ,术后必须随访膀胱镜、B超等
Objective To discuss the incidence and diagnosis of primary ureteral tumors and to analyze the surgical methods of this disease. Methods Sixteen patients with clinically gross hematuria were examined preoperatively and postoperative pathology was reported as transitional cell carcinoma. Results The results of preoperative examination were: 16 cases of venous urography, 4 cases of non-visualization, 12 cases of hydronephrosis; cystoscopy in 14 cases, 3 cases of ureteral tumor; retrograde pyelography in 11 cases, 5 cases of intubation 6 cases of hydronephrosis, including hydronephrosis, including 6 cases of ureteral tumor, 1 case of retroperitoneal mass; CT examination in 3 cases, 1 case of retroperitoneal mass, 2 cases of hydronephrosis; exfoliation Cell examination in 6 cases, 2 cases found tumor cells. 16 patients underwent surgical treatment. Postoperative pathological examination showed 16 cases of transitional cell carcinoma. Conclusions that palliative surgery is feasible for early solitary cases, full-length ureterrectomy for invasive advanced stage tumors, and postoperative follow-up of cystoscopy, B-
