Retroperitoneal laparoendoscopic single-site radical nephrectomy using a low-cost, self-made device: initial...

Area of Science:

• Urology
• Surgical Innovation
• Minimally Invasive Surgery

Background:

• Radical nephrectomy is a standard treatment for renal cancer.
• Conventional laparoscopy offers minimally invasive benefits but can be complex.
• Single-port surgery aims to further reduce invasiveness and improve cosmesis.

Purpose of the Study:

• To introduce a novel, low-cost, self-made single-port device for retroperitoneal laparoscopic radical nephrectomy.
• To evaluate the outcomes of this new device compared to conventional laparoscopic surgery.

Main Methods:

• Retrospective analysis of 29 patients undergoing retroperitoneal laparoendoscopic single-site radical nephrectomy (RLSS-RN) using a self-made device.
• Comparison with a matched control group of 29 patients who underwent conventional laparoscopy.
• Analysis of patient demographics, cancer staging, and postoperative outcomes.

Main Results:

• No significant differences were observed in patient demographics (age, gender, BMI) or cancer characteristics (T stage, tumor diameter) between the groups.
• The RLSS-RN group showed a statistically significant shorter duration of postoperative hospitalization (7.14 ± 1.38 days) compared to the conventional laparoscopy group (8.17 ± 1.54 days).

Conclusions:

• The self-made single-port device for retroperitoneal laparoscopic radical nephrectomy is a feasible and safe surgical option.
• This approach represents a low-cost strategy for performing minimally invasive radical nephrectomy.
• Further investigation may support wider adoption of this technique.
