Laparoendoscopic single site surgery in urology: A single centre experience

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Innovation

Background:

• Single port surgery, also known as laparoendoscopic single site surgery (LESS), is an evolving minimally invasive technique.
• Evaluating the safety and efficacy of LESS across various urologic procedures is crucial for its wider adoption.

Purpose of the Study:

• To analyze the experience with 87 cases of laparoendoscopic single site surgery (LESS) in urologic procedures.
• To assess the outcomes, complications, and feasibility of LESS for nephrectomy and reconstructive surgeries.

Main Methods:

• Retrospective analysis of 87 LESS procedures performed between December 2007 and June 2010.
• Procedures included donor nephrectomy, simple nephrectomy, radical nephrectomy, pyeloplasty, and ureteroneocystostomy.
• Key parameters analyzed: operating room time, blood loss, pain scores, complications, warm ischemia time, and graft outcomes.

Main Results:

• LESS donor nephrectomy showed a mean warm ischemia time of 6.9 minutes with good recipient graft outcomes.
• Complications were infrequent, including one instance each of major vascular/bowel injury and two diaphragmatic injuries.
• Reconstructive procedures like pyeloplasty and ureteroneocystostomy demonstrated successful functional outcomes and good drainage.

Conclusions:

• Laparoendoscopic single site surgery (LESS) is a safe and effective approach for nephrectomy and reconstructive urologic procedures.
• LESS offers advantages in cosmesis and patient recovery compared to standard laparoscopy.
• Further randomized controlled trials are recommended to validate LESS donor nephrectomy's long-term efficacy.
