摘要
目的 提高肾良性肿瘤和瘤样病变的诊治水平。 方法 肾良性肿瘤和瘤样病变 4 9例 ,均行B超和CT检查 ,14例行MRI检查 ,分析临床表现、病理和影像学特点。 2 1例术前未能确诊 ,按肾癌行肾切除术 ;2 8例行保留肾单位的肿瘤切除术。 结果 各种病变临床症状无特异性。血管平滑肌脂肪瘤CT和MRI表现含脂肪组织的影像学特点。彩超检测 2例肾动脉瘤和 2例动静脉瘘有特异性表现。其他良性病变无特异性影像学表现。行保肾手术的 2 8例患者随访 1～ 9年无复发 ,肾功能正常。 结论 B超、CT、MRI和彩超等影像学检查对肾良性肿瘤和病变有重要诊断价值。有依据的保留肾单位的肿瘤切除术和术中行冰冻病理检查可减少误诊误治。
Objective To evaluate the differentiation and diagnosis of benign renal tumors and tumor-like lesions. Methods The data of 49 cases of benign renal tumors and tumor-like lesions were retrospectively analyzed.All the 49 cases underwent B-ultrasonography and CT;14 cases underwent MRI.The clinical manifestation,imaging features and the pathological results were evaluated.21 cases of benign renal tumors and tumor-like lesions were misdiagnosed as renal carcinoma and underwent nephrectomy.28 cases underwent nephron-sparing tumor excision. Results There was no specificity of the clinical presentation in all the cases.CT and MRI showed that angiomyolipoma had imaging features of intra-tumoral fat.Color Doppler ultrasonography showed the specific features of renal arterio-venous fistula and renal artery aneurysms.The other imaging features of benign renal tumors and tumor-like lesions had no specificity.28 cases who underwent nephron-sparing surgery were followed up for 1 to 9 years and had no relapse.Their renal functions were normal. Conclusions Bulltrosonography,CT and MRI are contributive to the diagnosis and treatment of benign renal tumors and tumor-like lesions.Using nephron-sparing surgery for indeterminate renal masses may reduce misdiagnosis and unnecessary nephrectomy.
