Abstract:

To evaluate the efficacy of preoperative planning and intraoperative image navigation in combination with three-dimensional (3D) visualization for a laparoscopic partial nephrectomy (PN) procedure, we examined the results of our cases and compared those with previously reported studies. From September 2009 to June 2015, 6 patients with cT1 renal tumors underwent 3D laparoscopic PN in combination with preoperative planning and intraoperative image navigation at our hospital. The tumor cutting line and clamping portions of the renal artery were preoperatively determined based on reconstructed 3D images. Real-time navigation was performed during the operation. Average operative and ischemia times were 442 and 28.5 minutes, respectively, while blood loss was 129 ml. Renal function shown by creatinine level after surgery was comparable to the preoperative measurements. The pathological diagnosis in each case was renal clear cell carcinoma with a negative margin. There were no complications related to the procedures. All patients survived without recurrence after a mean follow-up period of 38 months. Our results suggest that preoperative planning and intraoperative image navigation in combination with use of a 3D laparoscopic system is feasible and useful for laparoscopic PN.
