Abstract

Introduction: Laparoscopic nephrectomy (LN) is likely the most common laparoscopic procedure performed by general urologists without formal laparoscopic training. The traditional technique is cumbersome because it entails making an early approach to the hilum with the risk of bleeding and need for conversion. We perform a different technique that we believe is simpler to learn and to teach. It consists of a complete dissection of the inferior and posterior aspects of the kidney, followed by en bloc stapling of the renal hilum. The present report is a detailed description of our technique including outcomes and complications. Materials and Methods: Perioperative data of 129 consecutive patients who underwent LN between November 2003 and September 2007 were prospectively collected and retrospectively reviewed. Complications were reported using the Clavien classification system, and follow- up was performed according to our institution’s protocol and included physical examination, blood count, blood chemistry, and renal function tests at every visit, in addition to abdominal computed tomography scan six months after surgery. Additional imaging was scheduled according to disease stage and grade. Results: Mean patient age, tumor size, and operative time were 63 ± 15.6 years, 6.3 ± 2.4 cm, and 128 ± 41.4 minutes, respectively. Median estimated blood loss was 0 mL (0.200). Conversion to open surgery occurred in 3.1% of patients, and 8% of the patients had a blood transfusion. Complications were recorded in 26% of the patients; 91% of them had Clavien grade scores of 1 or 2. Conclusion: We present a standardized technique for LN. Its main advantage is that postpones any manipulation of the hilum to a later step during the procedure when it is easy to identify and control. This decreases early bleeding and main vascular complications.
