【摘要】 目的:探讨肾错构瘤(RAML)的诊断和治疗方法。方法:对102例RAML患者按肿瘤直径分为3组:A组(<4cm)21例,B组(4～≤8cm)63例,C组(>8cm)18例;A组中17例(81%)患者无任何症状,治疗以定期随访为主。B组中50例(79%)患者有临床症状,52例行保留肾单位手术,4例行肾切除术,2例行肾癌根治切除术,5例患者定期随访。C组中16例(88%)患者有临床症状,所有病例都进行了手术治疗,10例行保留肾单位手术,6例行肾切除术,其中2例行肾癌根治切除术,1例行选择性肾动脉栓塞术,后择期行肾切除术,1例因伴发下腔静脉瘤栓而同时行了下腔静脉瘤栓取出术。结果:所有病例术后病理检查均证实为RAML。结论:肿瘤直径<4cm的患者多无临床症状,可临床随访;肿瘤直径≥4cm的患者应积极行手术治疗,以保留肾单位的手术为首选。更多还原

【Abstract】 Objective:To discuss the diagnosis and treatment of renal leiomyolipoma.Methods:Clinical data of 102 cases of renal leiomyolipoma were reviewed retrospectively. The cases were divided in 3 groups based on the size of single largest tumor: Group A(<4 cm), Groups B(4～≤8 cm), Groups C(>8 cm). In Group A, 81%(17/21) of the patients were asymtomatic, regular followed up was primary. In Groups B, 79%(50/63) had clinical complaints. Of the 63 cases, Nephron-sparing surgery was done in 52, nephrectomy in 4, radical nephrectomy in 2, regular follow-up in 5. In Group C, 88%(16/18) of the patients were symptomatic, all patients acquired surgical operation including Nephron-sparing surgery was done in 10, radical nephrectomy in 2, selective emergency arterial embolization followed by nephrectomy in 1, nephrectomy in 6 of which dislodged tumor embolus from postcava in 1.Results:All cases were confirmed renal leiomyolipomas by pathology after operation.Conclusions:The patients with RAML<4 cm are likely to be asymtomatic and should be observed, With RAML≥4 cm, surgery is ecessary. Nephron-sparing surgery(NSS) is optimum choice.更多还原
