目的探讨肾错构瘤的临床表现、影像学特点和治疗方式的选择原则。方法回顾分析2005年至2009年收治的19例肾错构瘤患者的临床资料。结果 19例经手术及病理诊断为肾错构瘤。9例采用保留肾单位手术(3例为肿瘤剜除术,6例为肾部分切除术),6例行肾切除术,4例误诊肾癌行根治术。术后无出血、尿瘘等并发症。13例获随访5个月～5年,均无肿瘤复发,肾功能均良好。结论 B超和CT是诊断肾错构瘤的重要检查方法。治疗方案取决于肿瘤大小、数量、部位等,尽可能选择保留肾单位手术。
Objective To explore the clinical manifestations, imaging features and treatment principles of renal hamartoma. Methods The clinical data of 19 patients with renal hamartoma admitted from 2005 to 2009 were retrospectively analyzed. Results 19 cases were diagnosed as renal hamartoma by operation and pathology. Nine patients were treated with retained nephron (3 with tumor excision and 6 with partial nephrectomy), 6 with nephrectomy and 4 with misdiagnosis of renal cell carcinoma. No postoperative bleeding, urinary fistula and other complications. Thirteen patients were followed up for 5 months to 5 years, no tumor recurrence, renal function were good. Conclusion B-ultrasound and CT are important diagnostic methods of renal hamartoma. Treatment options depend on tumor size, number, site, etc., as far as possible choose to retain nephron surgery.
