We report two patients who underwent laparoscopic partial nephrectomy using a microwave tissue coagulator who suffered relatively severe complications. One was a 63-year-old man whose serum creatinine level gradually increased postoperatively and in whom ipsilateral renal function was almost lost at 3 months postoperatively. We suspect that the microwave coagulator came into contact with the main renal artery and that blood supply to the affected kidney was stopped in this case. In another 46-year-old woman, prolonged leakage of urine was observed in the postoperative period, but resolved after 2 months. We speculated that the cause of this leakage was irreversible damage to collecting system tissue by the microwave coagulator. In conclusion, care is needed concerning the portion of tissue and depth of needle insertion in laparoscopic partial nephrectomy using a microwave tissue coagulator.
