Comparison of laparoscopic versus robotic assisted partial nephrectomy: one surgeon's initial experience

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Partial nephrectomy is a standard treatment for small renal masses.
• Laparoscopic and robotic approaches are common surgical techniques.
• Comparing perioperative outcomes of these techniques is crucial for surgical decision-making.

Purpose of the Study:

• To compare perioperative outcomes between laparoscopic and robotic partial nephrectomy.
• To assess the impact of surgical approach on warm ischemia time and complication rates.
• To evaluate the surgeon's experience with consecutive laparoscopic and robotic partial nephrectomies.

Main Methods:

• Retrospective review of 15 laparoscopic and 13 robotic partial nephrectomies for small renal tumors.
• Comparison of patient demographics, tumor characteristics, intraoperative, and postoperative data.
• Statistical analysis using Student t-test, Wilcoxon rank-sum, or Chi square test.

Main Results:

• Robotic partial nephrectomy demonstrated significantly shorter warm ischemia time (29.7 min vs. 39.9 min, p < 0.0001).
• Operative time was longer in the robotic group (352 min vs. 253 min, p < 0.0001).
• No significant differences in hospital stay or complication rates; fewer conversions to radical nephrectomy in the robotic group.

Conclusions:

• Robotic partial nephrectomy is associated with reduced warm ischemia time compared to laparoscopic partial nephrectomy.
• Increased operative time is noted with the robotic approach.
• Both techniques achieve negative surgical margins, with robotic potentially reducing the need for conversion to radical nephrectomy.
