Retroperitoneal laparoendoscopic single-site (LESS) simple nephrectomy is a feasible and safe approach for benign kidney conditions. While technically demanding, it offers cosmetic benefits and should be selectively applied based on patient factors.

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Retroperitoneal laparoendoscopic single-site (LESS) surgery is an evolving technique.
  • Simple nephrectomy is a common urological procedure.

Purpose of the Study:

  • To evaluate the early experience and outcomes of retroperitoneal LESS simple nephrectomy.
  • To assess the feasibility, safety, and cosmetic benefits of this approach.

Main Methods:

  • 16 patients with benign nonfunctioning kidneys underwent retroperitoneal LESS nephrectomy.
  • A single port was utilized via a lumbar incision, employing specialized laparoscopic instruments.
  • The procedure was performed by a single experienced laparoscopic surgeon.

Main Results:

  • Successful completion in 15 out of 16 cases; one conversion to open surgery due to adhesions.

  • Mean operative time: 85 minutes; mean blood loss: 56 mL.
  • Mean oral diet resumption: 1.5 days; mean hospital stay: 4 days; minimal complications.

    • Conclusions:

    • Retroperitoneal LESS simple nephrectomy is feasible and safe when performed by experienced surgeons.
    • The technique offers improved cosmesis but remains technically challenging.
    • Selective application based on patient condition is recommended.
