射频消融治疗功能性孤立肾肾细胞癌的临床分析

目的 探讨射频消融治疗功能性孤立肾肾细胞癌的可行性及临床疗效. 方法对5例功能性孤立肾肾细胞癌患者实施射频消融治疗.B超、CT扫描检查肿瘤位于左肾3例,右肾2例.肿瘤最大径3.0～6.0 cm,未发现远处转移灶.T1aN0M0 3例,T1bN0M0 2例.术前常规实验室检查,术后采用增强CT扫描(CECT)、超声造影(CEUS)定期随访. 结果 5例平均手术时间(100.0±28.5)min,平均出血量(95.0±30.5)ml,术中、术后均未输血.术后均有发热,体温(38.2±0.7)℃.术后1周CEUS示5例肾癌病灶均完全消融.血红蛋白(Hb)、血肌酐(SCr)、患侧ECT-肾小球滤过率(ECT-GFR)和肌酐清除率(Ccr)较术前均无明显变化(P>0.05).随访5～19个月,中位数11.5个月,均未见复发,SCr维持(87.5±17.3)μmol/L. 结论 射频消融治疗功能性孤立肾肾细胞癌具有保留肾单位、并发症少及恢复快等优势,是目前治疗功能性孤立肾肾细胞癌一种可选择的方法.

Radiofrequency ablation for renal cell carcinoma in functional solitary kidney

Objective To evaluate the clinical feasibility of radiofrequency ablation (RFA) for renal cell carcinoma in functional solitary kidney. Methods Five selected cases of primary renal cell carcinoma in a functional solitary kidney were retrospective analyzed. Three cases of left renal cell carcinoma and 2 cases of right renal cell carcinoma were diagnosed by B ultrasound and CT scanning. The maximum diameter of the tumors were 3.0- 6.0 cm. Three cases of which were T1a N0 M0 and the others Were T1bN0M0. All patients were followed up with enhanced-CT and contrast-enhanced ultrasonography. Results The mean time of the operation was 100.0+28.5 min, and the mean blood loss was 95.0±30.5 ml. No patients accepted blood transfusion post-operation. All patients after operation had fever (38.2±0. 7 ℃ ). All the lesions were completely ablated on contrast-enhanced ultrasonography. There was no statistic change of hemoglobin, serum creatinine (SCr), ECT-GFR and creatinine clearance after operation (P>0.05). All of the 5 cases survived. No recurrence were found by enhanced-CT and contrast-enhanced ultrasonography and SCr was retaining in the normal level during follow-ups (median, 11.5 months). Conclusion Radiofrequency ablation for renal cell carcinoma in a functional solitary kidney could be a treatment choice with a relatively low incidence of complications.
