Radiofrequency ablation for renal cell carcinoma in functional solitary kidney / 中华泌尿外科杂志

ABSTRACT

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.
