Retroperitoneal Laparoendoscopic Single-Incision Radical Nephrectomy Without Special Platforms: A Single-Center...

Area of Science:

• Urology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Retroperitoneal laparoscopic radical nephrectomy (LRN) is a standard procedure for kidney cancer.
• Single-incision laparoscopic surgery aims to reduce invasiveness and improve cosmetic outcomes.
• Laparoendoscopic single-site radical nephrectomy (LESI-RN) explores novel approaches to minimally invasive kidney surgery.

Purpose of the Study:

• To describe the initial experience with retroperitoneal LESI-RN using conventional laparoscopic instruments.
• To assess the safety and feasibility of this modified LESI-RN technique.
• To compare LESI-RN outcomes with conventional LRN.

Main Methods:

• Twenty patients underwent retroperitoneal LESI-RN via a 5-cm arc incision.
• Conventional laparoscopic instruments were used with trocars placed within the incision.
• Perioperative data were retrospectively analyzed and compared to a cohort of patients who underwent conventional LRN.

Main Results:

• LESI-RN demonstrated significantly lower visual analogue scale pain scores and reduced analgesic requirements compared to LRN.
• Operation time was longer for LESI-RN than for conventional LRN (P=.001).
• Time to liquid intake and hospital stay were similar between the two groups (P>.05).

Conclusions:

• Retroperitoneal LESI-RN is a safe and feasible surgical strategy.
• This technique combines principles of conventional LRN with the cosmetic and minimally invasive benefits of single-site surgery.
• LESI-RN achieves comparable surgical and oncological efficacy to LRN, with enhanced pain control and cosmetic results.
