目的 探讨肾脏良性肿瘤的诊断与治疗。方法 对 1983～ 1999年收治的 3 7例肾脏良性肿瘤进行回顾性分析。结果 肾脏良性肿瘤占同期收治肾脏肿瘤的 9.49%。临床有症状 2 2例 (5 9.45 % ) ,主要表现为患侧腰痛 ;有体征 5例 (13 .5 1% ) ,均表现为腹部包块。另 15例 (4 0 .5 4% )体检时行超声检查发现。术前通过超声和 CT确诊 2 4例 (64 .86% )。治疗方法主要是肿瘤切除术 ,但要根据术中肿瘤情况决定 ,必要时做肾切除。术后病理主要为血管平滑肌脂肪瘤 3 0例 (81.0 8% ) ,其次为嗜酸细胞腺瘤 5例 (13 .5 1% )。结论 肾脏良性肿瘤较恶性肿瘤少见 ,临床表现缺乏特异性 ,超声及 CT是诊断的重要手段。治疗时应将肿瘤完整切除。肾血管平滑肌脂肪瘤是主要的病理类型
Objective To investigate the diagnosis and treatment of benign renal neoplasm. Methods A retrospective analysis of 37 cases of benign renal neoplasm admitted to our hospital from 1983 to 1999 was performed. Results Renal benign tumors accounted for 9.49% of renal tumors in the same period. Clinical symptoms of 22 cases (5 9.45%), mainly as ipsilateral lower back pain; 5 cases were signs (13.51%), showed abdominal mass. The other 15 cases (40.54%) were examined by ultrasonography. Preoperative ultrasound and CT confirmed 24 cases (64.86%). The main treatment is tumor resection, but according to intraoperative tumor decision, if necessary, to do nephrectomy. The main pathology was 30 cases (81.0%) of angiomyolipoma, followed by 5 cases of eosinophilic adenoma (13.51%). Conclusions Compared with malignant neoplasms, renal benign tumors are rare, and their clinical manifestations are not specific. Ultrasonography and CT are important diagnostic methods. Tumor should be completely removed. Renal vascular smooth muscle lipoma is the major pathological type
