摘　　要：目的探讨肾集合管癌(collecting duct carcinoma,CDC)误诊的原因,提高本病的临床诊治水平。方法回顾性分析我院1例误诊为肾盂肾炎的CDC临床资料。结果患者因全程无痛性肉眼血尿1月余,当地医院查尿常规考虑为肾盂肾炎,治疗无效转入我院,CT检查示右肾占位性病变,行右肾肿瘤根治性切除术,术后病理检查及免疫组化证实为CDC,患者术后恢复顺利,随访5个月生活质量良好。结论 CDC临床较为罕见并具有很强侵袭性,病理学检查是确诊CDC的唯一可靠方法,治疗以根治性肾切除为主,术后坚持随访。Objective To discuss the misdiagnosis cause of renal collecting duct carcinoma（CDC）,and to improve the diagnosis and treatment level of the disease.Methods The clinical data of a patient with CDC misdiagnosed as pyelonephritis were retrospectively analyzed.Results The patient was regarded as having pyelonephritis in local hospital for presenting full range indolent hematuria over a month,and was admitted to our hospital.CT detection showed occupying lesion on the right kidney,and the patient underwent radical ectomy of the right kidney.Postoperative pathology diagnosis showed CDC,which was confirmed by immunohistochemisty.The patient recovered successfully after surgery,and survived with good life quality during a 5-month follow-up.Conclusion CDC is a rare kind of disease with strong invasion.Pathology examination is one of the most reliable methods in diagnosis of CDC.Radical nephrectomy is the first option,and postoperative follow-up should be persistent.
