Laparoscopic partial nephrectomy.

Area of Science:

• Urologic Oncology
• Minimally Invasive Surgery
• Nephrology

Background:

• Partial nephrectomy is oncologically equivalent to radical nephrectomy in select patients.
• Laparoscopic radical nephrectomy (LRN) has emerged as a viable alternative to open surgery.

Purpose of the Study:

• To describe the technique and outcomes of laparoscopic radical nephrectomy.
• To evaluate the feasibility and oncologic efficacy of LRN in a large patient series.

Main Methods:

• Retrospective review of over 415 LRN procedures performed between September 1999 and August 2004.
• Detailed description of surgical technique including imaging, approach (transperitoneal/retroperitoneal), dissection, hilar clamping, tumor resection, and closure.
• Intraoperative ultrasonography for tumor delineation and indigo carmine for pelvicaliceal repair assessment.

Main Results:

• LRN was successfully performed in over 415 patients over a 5-year period.
• The described surgical technique, including specific closure methods, was consistently applied.
• Initial patient selection focused on small, exophytic tumors, with criteria expanding with surgeon experience.

Conclusions:

• Laparoscopic radical nephrectomy provides oncologic efficacy similar to traditional radical nephrectomy for properly selected patients.
• The described surgical technique is detailed and reproducible, allowing for successful application in a significant patient volume.
• Surgeon experience and comfort level are key factors in expanding patient selection criteria for LRN.
