【摘要】 目的:探讨肾错构瘤(RAML)的诊断和治疗方法。方法:对78例RAML患者按肿瘤直径分为3组:A组(<4 cm)18例,B组(4~8 cm)52例,C组(>8 cm)9例;A组中15例(83%)患者治疗以定期随访为主;B组中40例患者(77%)有临床症状,行保留肾单位手术,10例行肾切除术,2例行肾根治切除术;C组7例(78%)患者有临床症状,均进行了手术治疗,5例行保留肾单位手术,4例行肾切除。结果:所有手术病例术后病理检查均证实为RAML。结论:肿瘤直径<4 cm的患者多无临床症状,可临床随访;肿瘤直径≥4 cm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 explore the diagnosis and treatment of renal angiomyolipoma(RAML).Methods:Clinical data of 78 cases of renal angiomyolipoma were reviewed retrospectively.The cases were divided in 3 groups based on the size of single largest tumor:Groups A(<4 cm),Groups B(4~8 cm),Groups C(>8 cm).In group A,83%(15/18)of the patients were asymptomatic,regular followed up was primary.In group B,77%(40/52)had clinical complaints,and nephron-sparing surgery was done in 40 cases,nephrectomy in 10 cases,radical nephrectomy in 2 cases.In group C,78%(7/9)of the patients were symptomatic,all patients acquired surgical operation including nephron-sparing surgery was done in 5 cases,nephrectomy in 4 cases.Results:All cases were confirmed renal angiomyolipoma by pathology after operation.Conclusion: The patient with RAML<4 cm is likely to be asymptomatic and should be observed,while RAML ≥4 cm,surgery treatment is necessary,and nephron-sparing surgery(NSS) is optimum choice.更多还原
