Intermediate-term prospective results of radiofrequency-assisted laparoscopic partial nephrectomy: a non-ischaemic coagulative technique.

OBJECTIVE To report the first intermediate-term oncological outcomes of laparoscopic radiofrequency coagulation followed by laparoscopic partial nephrectomy (RF-LPN) to treat small renal masses, as LPN is limited by the technical difficulty of efficient tumour resection and parenchymal repair during warm ischaemia of the kidney. PATIENTS AND METHODS A prospective database was searched to identify patients treated with RF-LPN; in each case the tumour was first RF coagulated with a margin of normal parenchyma, and then excised. Only fibrin glue was applied to the haemostatic resection site to prevent urinary leaks.
