title: Retroperitoneoscopic partial nephrectomy using radiofrequency ablation.
abstract: Two patients with renal tumors underwent retroperitoneoscopic partial nephrectomy. The renal tumors were initially treated with radiofrequency ablation. This method allowed tumor excision to be achieved without clamping the renal pedicle. Residual renal function was well maintained as determined by enhanced computed tomography scanning and measurement of the serum creatinine level. There were no complications such as vascular damage or collecting system injury. The pathological diagnosis was clear cell carcinoma (pT1) in Patient 1 and was not determined in Patient 2 because of entire ablation. No recurrence has been observed after 3 years and 2 years of follow up, respectively. Radiofrequency ablation was useful for control of local bleeding during retroperitonaoscopic partial nephrectomy.
