[Retroperitoneal lymph node dissection for testicular tumor with renal autotransplantation: a case report].

: A case of testicular tumor (embryonal cell carcinoma with choriocarcinoma) in a 42-year-old man treated with renal autotransplantation is presented. After four courses of chemotherapy (carboplatin, vinblastine and bleomycin), we performed retroperitoneal lymph node dissection. At the operation, one of the swelling lymph nodes involved left renal artery completely, so we performed left renal autotransplantation and promoted more effective lymph node dissection. After the operation, renal function was impaired but returned completely in a short time. Autotransplantation provides excellent bench visualization of renal lesions and stable graft function. Therefore, this procedure should be taken into consideration when nephrectomy cannot be avoided.
