Summary
This study introduces a modified endoscopic donor nephrectomy technique, combining retroperitoneoscopic and transperitoneal hand-assisted methods for safe and effective kidney removal. The novel approach ensures excellent visualization and preserves kidney function, with no complications in initial cases.
Area of Science:
- Nephrology
- Surgical Innovation
- Minimally Invasive Surgery
Background:
- Traditional donor nephrectomy techniques can be invasive.
- Endoscopic approaches aim to minimize donor morbidity.
- Optimizing surgical access and visualization remains a challenge.
Purpose of the Study:
- To present a novel, modified endoscopic donor nephrectomy procedure.
- To evaluate the safety and feasibility of this technique.
- To assess the preservation of renal function and operative field quality.
Main Methods:
- A two-stage dissection: retroperitoneoscopic posterior dissection followed by transperitoneal hand-assisted anterior dissection.
- Dissection of the renal artery, ureter, and gonadal vein.
- Focus on safe and easy dissection of the renal pedicle.
Main Results:
- The modified endoscopic donor nephrectomy was successfully performed in two donors.
- No intraoperative or postoperative complications were observed.
- The technique provided excellent operative fields for both posterior and anterior kidney aspects.
Conclusions:
- The modified endoscopic donor nephrectomy is a safe and feasible minimally invasive procedure.
- This technique effectively preserves renal function.
- It offers superior visualization for comprehensive kidney dissection.
