Retroperitoneoscopic microwave ablation of renal hamartoma: middle-term results.
The safety and efficacy of retroperitoneoscopic microwave ablation (MWA) in the treatment of renal hamartoma were evaluated. From July 2007 to July 2009, a total of 16 cases of renal hamartoma were treated with retroperitoneoscopic MWA. Peri- and post-operative findings were observed. Middle-term efficacy was assessed by contrast-enhanced computerized tomography (CT) in follow-up period. All patients received MWA of 1-5 points. The mean operative time was 85 min and the mean blood loss was 65 mL. During a median follow-up of 16 months, no evidence of disease recurrence was observed despite of incomplete ablation in 1 case. Retroperitoneoscopic MWA is a relatively simple procedure with less impact to renal function and less complication. The outcome of middle-term follow-up is satisfactory. Thus, retroperitoneoscopic MWA appears to be a safe and effective technique for renal hamartoma in selected patients.
