肾血管平滑肌脂肪瘤(以下简称肿瘤)是不罕见的良性肿瘤,由不同比例的成熟脂肪组织、厚壁血管组织以及平滑肌组织构成.过去主要是在肿瘤急性出血或无法与肾癌鉴别时才做处理。肾切除术是标准的治疗手段。1976年前所有报道的不伴结节样硬化的肾血管平滑肌瘤病人做肾切除术占93%。随着诊断和治疗技术的发展,目前大多数泌尿外科医生同意对这种肿瘤采用较为保守的治疗。作者温习有关文献,结合13例病人进行分析。按肿瘤大小及有否症状将肾血管平滑肌脂肪瘤分为4类:(1)有症状者,肿瘤直径在4厘米或>4厘米;(2)无症状者,肿瘤直径在4厘米或>4厘米;(3)有症状,肿瘤直径<4厘米;(4)无症状,肿瘤直径<4厘米。根据上述分类作者制定以下4条治疗方案;(1)肿瘤直径在4厘米或>4厘米的有症状的病人,应行肾动脉造影,并考虑同时行
Renal angiomyolipoma (hereinafter referred to as tumor) is an uncommon benign tumor composed of different proportions of mature adipose tissue, thick-walled vascular tissue, and smooth muscle tissue. In the past, it was mainly performed when the tumor was acutely bleeding or when it could not be differentiated from renal cancer. deal with. Nephrectomy is the standard treatment. All cases of renal angiomyolipoma without reported nodules-like sclerosis before 1976 accounted for 93% of nephrectomy patients. With the development of diagnostic and therapeutic techniques, most current urologists agree to adopt more conservative treatment for this type of tumor. The author reviewed the relevant literature and analyzed 13 patients. Renal angiomyolipomas were categorized into 4 categories according to tumor size and presence of symptoms: (1) Symptomatic patients with a tumor diameter of 4 cm or >4 cm; (2) Asymptomatic patients with a tumor diameter of 4 cm or >4 Centimeter; (3) symptomatic, tumor diameter <4 cm; (4) asymptomatic, tumor diameter <4 cm. According to the above classification authors, the following 4 treatment plans were formulated; (1) Renal artery angiography should be performed in symptomatic patients with a tumor diameter of 4 cm or > 4 cm
