OBJECTIVE To investigate the outcome and indications for radical nephrectomy with a Chevron incision to treat complicated renal carcinoma.METHODS Large renal carcinomas were found in 15 patients during a preoperative CT and/or MRI examination. A tumor thrombus in the renal vein or inferior vena cava was found in 5 cases, and a complication of metastasis in the contralateral adrenalgl and was found in 2 patients. All of the 15 patients underwent a radical nephrectomy by a chevron incision and the postoperative pathological results noted.RESULTS Of the 15 patients who underwent a radical nephrectomy and lymphadenectomy, 5 also received a thrombectomy, and 2 a contralateral adrenalectomy. All surgical operations were safe and successful. The mean operation time was (4.45±0.83) h, and the intraoperative blood loss was (785±910) ml. All patients recovered well after the surgery. Multimodal therapy was conducted in these cases, with rigorous follow-up.CONCLUSION In determining the type of incision for surgery of renal carcinoma, a chevron incision is suitable for cases with a large tumor, local nodal metastasis, thrombus of the renal vein or inferior vena cava and complicated metastasis to the contralateral adrenal gland. The incision produces a clear operating field with less intra- and post-operative complications.
