    Background : We evaluated the surgical outcomes of non-ischemic, non-renorrhaphy Laparoscopic partial nephrectomy (LPN) using a microwave tissue coagulator (MTC) for small renal tumors.

    Methods : From June 2003 to February 2014, 75 patients with small renal tumor underwent non-ischemic, non-renorrhaphy LPN with an MTC.

    Results : The median operative time was 167 minutes and the median estimated blood loss was 6 mL. No patient had conversion to radical nephrectomy.

    The histopathological study revealed renal cell carcinoma in 63 cases and a positive surgical margin causing local recurrence in one. Five-year local recurrence-free survival is 97.8%. There was no significant difference in eGFR during perioperative values.

    Conclusions : Non-ischemic, non-renorrhaphy LPN with an MTC for small renal tumors seems to be a simple and less invasive surgical option without a loss of renal function.
