Retrospective Analysis of Laparoscopic Partial Nephrectomies Using the Zero Ischemia Technique

Area of Science:

• Urology
• Minimally Invasive Surgery
• Nephrology

Background:

• Partial nephrectomy is the gold standard for small renal masses.
• Minimally invasive techniques like laparoscopic partial nephrectomy (LPN) are increasingly utilized.
• The
• zero ischemia
• technique aims to improve renal function preservation during LPN.

Purpose of the Study:

• To evaluate the outcomes of 89 off-clamp laparoscopic partial nephrectomies (LPN).
• To assess the feasibility and safety of performing LPN without hilar clamping.
• To compare results with contemporary LPN data.

Main Methods:

• Retrospective analysis of 89 LPN cases performed between March 2008 and May 2014.
• Data collected included surgical characteristics, complications, postoperative outcomes, and renal function.
• Analysis focused on the
• zero ischemia
• technique without additional nephron-sparing manipulations.

Main Results:

• The median operative time was 154 minutes, with a 7.9% transfusion rate.
• Mean postoperative decline in glomerular filtration rate was 6.52 mL/min, with a creatinine elevation of 0.09 mg/dL.
• Complication rates included 2.3% intraoperative, 33.7% early postoperative, and 6.7% late postoperative events. Positive surgical margins occurred in 7.9% of cases.

Conclusions:

• Laparoscopic partial nephrectomy can be successfully performed without hilar clamping.
• The
• zero ischemia
• technique yields results comparable to contemporary LPN data.
• Larger prospective studies are needed to confirm the evidence-based advantages of this technique.
