目的 :探讨肾血管平滑肌脂肪瘤 (RAML)的诊治方法。方法 :回顾性分析 4 8例RAML患者的临床资料及诊治情况。结果 :B超 37例提示为错构瘤 (37/ 4 8) ,CT38例提示为错构瘤 (3895 ) ,7例行MRI检查者 6例提示肾错构瘤 (6 / 7)。 4 5例RAML患者行保肾手术 ,其中 10例继发破裂出血者行血肿清除瘤体剜除术 ;2 9例瘤体直径大于 2cm者行肿瘤剜除或肾部分切除术 ;6例直径小于 2cm者行腹腔镜下肿瘤切除术。 3例患者行肾切除术。所有病例术后病理检查均证实为错构瘤。结论 :B超 ,CT和MRI为肾错构瘤的最佳诊断方法。对已确诊的肾血管平滑肌脂肪瘤患者应积极进行手术治疗 ,手术治疗应尽量保留有功能的肾单位。
Objective: To investigate the diagnosis and treatment of renal angiomyolipoma (RAML). Methods: A retrospective analysis of 48 cases of RAML in patients with clinical data and diagnosis and treatment. Results: Twenty-seven cases of B-mode ultrasound showed hamartoma (37/48), CT38 cases showed hamartoma (3895), and 7 cases MRI showed 6 cases of renal hamartoma (6/7). 45 cases of RAML patients underwent kidney surgery, of which 10 cases of secondary hemorrhage were hematoma removal of tumor removal surgery; 29 cases of tumor diameter greater than 2cm were removed tumor or partial nephrectomy; 6 cases of diameter less than 2cm laparoscopic resection of the tumor. Three patients underwent nephrectomy. Postoperative pathological examination of all cases confirmed hamartoma. Conclusion: B-ultrasound, CT and MRI are the best diagnostic methods for renal hamartoma. The diagnosis of renal vascular smooth muscle lipoma patients should be actively surgical treatment, surgical treatment should try to retain functional nephron.
