Reoperative Partial Nephrectomy-Does Previous Surgical Footprint Impact Outcomes?

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Historically, open surgery was preferred for complex procedures.
• Minimally invasive techniques are increasingly adopted for partial nephrectomies.

Purpose of the Study:

• To compare perioperative outcomes, surgical footprints, and complication rates between open and robotic reoperative partial nephrectomy.
• To evaluate the impact of prior surgical approach on outcomes in reoperative partial nephrectomy.

Main Methods:

• Retrospective review of 192 patients undergoing reoperative partial nephrectomy.
• Patients were categorized into four cohorts based on current and prior surgical approaches (open/minimally invasive).
• Perioperative outcomes and complication factors were analyzed.

Main Results:

• Robotic surgery cohorts had significantly fewer blood transfusions, overall complications, and major complications (grade ≥3) compared to open surgery cohorts.
• Multivariate analysis indicated the robotic approach was protective against major complications (OR 0.3, p=0.02).
• Prior surgical approach was not a predictor of major complications.

Conclusions:

• Reoperative partial nephrectomy is feasible with both open and robotic approaches.
• The robotic approach is independently associated with fewer major complications.
• Prior surgical history is less critical to perioperative outcomes than the current surgical approach.
