目的:提高对肾癌泌尿男性生殖道转移的认识。方法:总结我院20年来收治的2例患者资料,例1肾癌术后转移至同侧输尿管膀胱,例2肾透明细胞癌同时转移至同侧肾盂输尿管膀胱及前列腺,结合文献就其临床表现、转移机制、诊断及治疗进行讨论。结果:例1行残留输尿管及膀胱袖状切除术,例2行右肾癌根治性切除加膀胱全切回肠膀胱术,例1术后5年死于远处转移,例2术后2个月死于全身衰竭。结论:肾癌的泌尿男生殖道转移少见,转移机制尚不完全清楚,手术切除转移灶是首选推荐的治疗方法,肾癌根治术据病变情况可同时切除同侧全长输尿管并膀胱袖状切除。
Objective: To improve understanding of urinary and male genital tract in renal cell carcinoma. Methods: To summarize the data of 2 patients admitted to our hospital for 20 years. In case 1, renal cell carcinoma metastasized to ipsilateral ureter and bladder, case 2 renal clear cell carcinoma metastasized to ipsilateral pyeloureteral ureter and prostate, combined with literature on clinical manifestations , Metastasis mechanism, diagnosis and treatment. Residual ureter and bladder sleeve resection in case 1, radical nephrectomy in 2 cases and total ileal nephroureterectomy in case 2, case 1 died of distant metastasis 5 years after operation, case 2 2 months after operation Died of systemic failure. CONCLUSION: Urinary male genital tract is rare in renal cell carcinoma. The mechanism of metastasis is not yet fully understood. Surgical resection of metastases is the preferred method of treatment. Radical nephrectomy can be performed simultaneously with resection of ipsilateral full-length ureter and sleeve sleeve resection .
