Abstract: Objective :To investigate the advantages and indications of radical nephrectomy withchevron incision for the treatment of complicated renal carcinoma. Methods :In the 15 cases with renalcarcinoma that were analyzed, CT and/or MRI performed before surgery showed large tumors. Five caseshad renal vein or inferior vena cava tumor thrombus and 2 cases had solitary metastases to the con-tralateral adrenal gland before surgery. All patients underwent radical nephrectomy and lymphectomywith chevron incision. Results :Radical nephrectomy and thrombectomy were carried out in 5 cases,and contralateral adrenalectomy was carried out in 2 cases. The operations were successful in all pa-tients. The mean operative time was 4.45± 0.83 hours. All 15 cases have been successfully followed up. Conclusion :Chevron incision is suitable for patients with large tumors, local lymphatic involvement,thrombus in the renal vein or inferior vena cava and solitary metastases to the contralateral adrenalgland. This method has good results and few complications.
