目的探讨肾癌保留肾单位手术的适应证、安全性及疗效。方法分析15例肾癌保留肾单位手术患者的临床资料。结果术后均顺利恢复出院,无继发出血、尿漏等并发症。随访时间10～107个月,平均42个月。有1例术后18个月非肿瘤性死亡,余14例无肾功能障碍、局部复发和远处转移。结论保留肾单位的肾癌切除术是较为安全、有效、可行的方法,局部复发率低。 Objective To investigate the indications, safety and efficacy of renal cell nephron surgery. Methods Clinical data of 15 patients with renal cell carcinoma retained by renal cell carcinoma were analyzed. Results All patients recovered smoothly and no complications such as secondary bleeding and urine leakage occurred after operation. Follow-up time of 10 to 107 months, an average of 42 months. There was 1 case of non-neoplastic death at 18 months after operation, and 14 cases had no renal dysfunction, local recurrence and distant metastasis. Conclusions Nephron excision with nephron preservation is a safe, effective and feasible method. The local recurrence rate is low.
