Comparative Analysis of Laparoscopic Versus Open Partial Nephrectomy for Renal Tumors in 200 Patients

Abstract

Open surgical partial nephrectomy remains the established standard for nephron sparing treatment of renal tumors. When applied to small renal tumors, the laparoscopic approach is associated with longer warm renal ischemia time, more major intraoperative complications and more postoperative urological complications. Our data also suggest that more deliberate efforts to achieve a wider surgical margin are necessary with the laparoscopic approach. Nevertheless, our data suggest that laparoscopic NSS is emerging as an effective, minimally invasive therapeutic approach with respect to renal functional outcome with the additional advantages of decreased postoperative narcotic use, earlier hospital discharge and a more rapid convalescence. Continued efforts are required to develop laparoscopic renal hypothermia techniques and facilitate intrarenal suturing, while minimizing warm ischemia time.
