目的　提高对原发性非特异性输尿管炎的认识。　方法　报告 3例原发性输尿管炎结合文献对其病因、病理、临床表现作一简要介绍 ,提出了本病与继发性非特异性输尿管炎、输尿管结核、输尿管阴性结石和输尿管癌的鉴别要点。并对本病的治疗方法进行了讨论。　结果　术前无一能明确诊断 ,误诊率较高。手术行输尿管部分切除输尿管膀胱再植术 1例 ,输尿管部分切除输尿管端端吻合术 2例 ,术后随诊效果较好。　结论　原发性非特异性输尿管炎术前诊断比较困难 ,确诊依靠病理学 ,治疗有赖于手术 ,预后较好 Objective To improve the understanding of primary non-specific ureteritis. Methods The report of 3 cases of primary ureteral inflammation combined with the literature on its etiology, pathology, clinical presentation made a brief introduction of the disease and secondary non-specific ureteral inflammation, ureteral tuberculosis, ureteral negative stones and ureteral cancer identification points. The treatment of this disease was discussed. Results None of the preoperative diagnosis can be made with a high rate of misdiagnosis. Surgical ureter partial resection of the ureter bladder replantation in 1 case, partial resection of the ureter in 2 cases of anastomosis, postoperative follow-up effect is better. Conclusion Preoperative non-specific ureteritis diagnosis is more difficult, diagnosis depends on the pathology, the treatment depends on the operation, the prognosis is better
