Summary

This modified laparoscopic nephrectomy uses only 3 trocars, reducing the need for extra instruments and retractors. The technique is safe and reliable for kidney removal, minimizing iatrogenic injury risks.

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Laparoscopic nephrectomy commonly requires multiple trocars and retractors, increasing the risk of iatrogenic injuries.
  • Standard procedures often utilize 5 ports, with 2 dedicated to retraction instruments.

Purpose of the Study:

  • To describe a modified transperitoneal laparoscopic nephrectomy technique.
  • To demonstrate a method using only 3 ports and no additional retractors.
  • To reduce the risk of surgical complications associated with laparoscopic nephrectomy.

Main Methods:

  • A 3-port transperitoneal approach was employed: 10 mm, 5 mm, and 12 mm trocars.
  • Key modifications included leaving posterosuperior kidney attachments intact during vascular control to maintain tension.

  • Specimen retrieval followed the division of remaining attachments.

    • Main Results:

    • All 14 laparoscopic nephrectomies were successfully completed using the 3-port technique without additional instruments.
    • No major intraoperative or postoperative complications occurred, with one instance of abdominal wall hematoma.
    • Average operative time was 120 minutes, and mean hospital stay was 5 days.

    Conclusions:

    • The modified 3-port laparoscopic nephrectomy is a safe and reliable surgical option.
    • Limiting trocar number and eliminating retractors enhances patient safety.
    • This technique offers a viable alternative to standard laparoscopic nephrectomy procedures.
