Comparative study of hybrid laparoendoscopic single-site (LESS) partial nephrectomy and conventional multiport...

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Partial nephrectomy is a standard procedure for kidney tumors.
• Minimally invasive techniques aim to improve patient outcomes and cosmesis.
• Hybrid laparoendoscopic single-site (LESS) surgery is an evolving approach.

Purpose of the Study:

• To compare surgical and oncological outcomes of hybrid LESS partial nephrectomy with reusable components against conventional multiport laparoscopy.
• To evaluate the safety and efficacy of hybrid LESS partial nephrectomy.

Main Methods:

• A prospective, paired, nonrandomized, comparative study.
• 20 patients underwent hybrid LESS partial nephrectomy with an auxiliary 3.5mm trocar.
• 26 patients underwent conventional multiport laparoscopy.

Main Results:

• No significant differences in operating time, ischemia time, blood loss, or complications.
• Hybrid LESS demonstrated shorter drainage time and hospital stay.
• No positive margins or tumor recurrence observed during follow-up (average 31 months).

Conclusions:

• Hybrid LESS partial nephrectomy is a safe and oncologically sound alternative to multiport laparoscopy.
• The primary benefit observed is a reduced hospital stay.
• No significant improvements in other surgical outcomes or cosmetic results were noted.
