腹腔鏡下腎部分切除術の治療成績

Abstract

The purpose of this study was to evaluate the safety and feasibility of laparoscopic partial nephrectomy with a small renal tumor. Between September 2004 and October 2014, 69 patients who underwent laparoscopic partial nephrectomy in Kansai Rosai Hospial were examined. The mean patient age was 60.3 years, and the mean tumor size was 24.5 mm. The mean estimated blood loss was 111 cc. The mean cold ischemic time was 59.7 minutes, and the mean warm ischemic time was 31.3 minutes. There were 5 complications : intraoperative ureteral injury, blood transfusion, postoperative perinephric hematoma, portsite bleeding, urinary fistula, respectively. All of the cases were cured with non-surgical treatment except ureteral injury which was repaired intraoperatively. The postoperative eGFR loss was 11%. At present, no patients have developed local recurrence or distant metastasis. The initial outcome of laparoscopic partial nephrectomy in our hospital was satisfactory in terms of safety, renal function and cancer control.
