原发性非特异性输尿管炎三例报告

目的探讨原发性非特异性输尿管炎术前诊断及治疗方法。方法总结3例原发性非特异性输尿管炎患者资料。男1例，女2例。年龄分别为28、38、68岁。1例体检B超发现右肾积水，临床无症状，2例表现为下腹隐痛。病变位于输尿管中段1例，下段2例。3例均经MRU结合输尿管镜检查诊断，行病变输尿管部分切除术治疗。结果3例术后病理报告均证实为输尿管炎性变，镜下表现为输尿管黏膜坏死组织及炎细胞浸润、血管扩张充血、肌层肥厚，纤维组织增生。术后随访2年，2例临床症状消失，3例IVU示尿路通畅。结论原发性非特异性输尿管炎病因不明，临床无典型表现，输尿管镜结合MRU检查有助于诊断，病变输尿管部分切除治疗效果良好。

Preoperative diagnosis and treatment of primary non-specific ureteritis (report of 3 cases)

Objective To evaluate the preoperative diagnosis and treatment of primary non-specific ureteritis,and to better understand this disease.Methods Three cases of primary non-specific ureteritis (1 man and 2 women)were reported.Their age was 28,38,68 years,respectively.One ease was found to have hydronephrosis on B-ultrasound at physical examination with no symptoms,and 2 had abdominal pain. The lesions were detected in lower part of the ureter in 2 cases,and in middle in I.The patients were diag- nosed preoperatively with combined use of MRU and ureteroscopy.Partial resection of the diseased part of the ureter was performed in all the cases.Results Pathological findings confirmed the diagnosis of non-spe- cific ureteritis.Microscopy showed necrotic tissue and inflammatory cell infiltration of ureteral mucosa,dilated and congested blood vessels,hypertrophic muscular layer,and proliferation of fibrous tissue.During the fol- low-up of 2 years,the patients had no symptoms and were free from hydronephrosis.Conclusions The eti- ology of primary non-specific ureteritis is unclear,and no typical symptoms can be found clinically.Combined use of MRU and ureteroscopy is helpful for definite diagnosis of the disease.Partial resection of the diseased part of the ureter has good results.
