The former included 3 rare cases of 17 a hydroxylase deficiency. Thelatter included 3 cases of feminizing adrenal tumor and 2 cases of virilizing adrenal tumor.Results: Weight, size and CT of the tumor, DHEA, 17 -ks, sex hormone levels, infiltration, andmetastasis were closely related to the degree of differentiation of the tumors. Conclusion:Virilizing and feminizing adrenal neoplasm were removed surgically by different incisions. Modifiedsubcostal incision was recommended as the best choice for huge adrenal mass. Corticoadrenal hormonetreatment fa CAH should be individualized according to the different types of the disease. Sexhormones were not suitable for children suffering from 17 hydroxylase deficiency before puberty.展开更多

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 adrenal gland 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 patierfts 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.展开更多
