Abstract

  The challenge of laparoscopic partial nephrectomy（LPN）is to resect a tumor within a limited warm ischemia time（WIT）, followed by hemostatic renorrhaphy under restricted movement of laparoscopic forceps. DaVinci device improved the movability of instruments and provided three-dimensional visualization.
  Since July 2010, we carried out seven cases of RALPN. Tumor size and WIT ranged from 15 to 62 mm, and from 13 to 37 minutes, respectively. RALPN was completed without open conversion or reoperation postoperatively. Urine leakage from the resected surface was noted in one case, which was successfully managed by urinary tract drainage.
  Introduction of daVinci device to LPN made this procedure, RALPN, a secured and promising one, leading to shorten the WIT and to achieve comfortable renorrhaphy. Even for the complex and technically challenging renal tumors, robotic assistance is expected to provide patients the benefit of minimally invasive surgery with maintenance of kidney function.
