The transition from laparoscopic to retroperitoneoscopic live donor nephrectomy: a matched pair pilot study

Area of Science:

• Urology
• Minimally Invasive Surgery
• Transplantation

Background:

• Retroperitoneoscopic live donor nephrectomy (RetroNeph) may reduce donor complications compared to transperitoneal laparoscopic nephrectomy (LapNeph).
• However, RetroNeph is less common and lacks direct comparative studies in unselected donors.

Purpose of the Study:

• To compare outcomes of RetroNeph with transperitoneal LapNeph in live kidney donors.
• To evaluate the safety and efficacy of implementing a RetroNeph program.

Main Methods:

• A single-center program switched from transperitoneal LapNeph to RetroNeph for all live donor nephrectomies in November 2007.
• Donor selection, port placement, and hand assistance remained consistent.
• Outcomes were compared between 45 RetroNeph cases and 45 pair-matched LapNeph cases.

Main Results:

• 87% of intended RetroNeph cases were completed retroperitoneoscopically, with no conversions to open surgery, transfusions, readmissions, or reoperations.
• No significant differences were found in warm ischemia time, donor outcomes, delayed graft function, recipient creatinine, or 1-year graft survival between RetroNeph and LapNeph groups.
• The implementation of RetroNeph did not adversely affect donor morbidity or early graft function.

Conclusions:

• Implementing a RetroNeph program did not negatively impact donor safety or graft function.
• The learning curve for RetroNeph appears short, making it a viable alternative to LapNeph.
• RetroNeph is a promising option, especially for surgeons experienced in LapNeph, due to its potential donor advantages.
