Laparoscopic versus open nephrectomy in 210 consecutive patients: outcomes, cost, and changes in practice patterns.

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Laparoscopic nephrectomy adoption is increasing in urology.
• Practice patterns and patient outcomes have transformed with its introduction.

Purpose of the Study:

• To compare the outcomes of laparoscopic and open nephrectomy within a single institution.

Main Methods:

• Retrospective analysis of elective nephrectomy cases (August 1998 - September 2002).
• Comparison of open (n=92) versus laparoscopic (n=118) procedures.
• Statistical analysis using Wilcoxon rank sum, chi-square, and Fisher's exact tests (p<0.05 significant).

Main Results:

• Laparoscopic nephrectomy showed significantly less blood loss (97ml vs 216ml), shorter length of stay (3.9 vs 5.9 days), and lower perioperative morbidity (14% vs 31%).
• Fewer wound complications (6.8% vs 27.1%) and faster convalescence for live donors (12 vs 33 days) were observed with the laparoscopic approach.
• Mean operative time was longer for laparoscopic cases (230 min vs 187 min), with higher hospital charges ($19,007 vs $13,581).

Conclusions:

• Laparoscopic nephrectomy leads to reduced blood loss, shorter hospitalizations, and fewer complications compared to open surgery.
• The benefits of faster recovery and reduced morbidity outweigh the increased initial hospital charges.
• Laparoscopic nephrectomy is a safe and effective alternative to open surgery.
