Laparoscopic donor nephrectomy yields kidneys with structure and function equivalent to those retrieved by open...

Area of Science:

• Nephrology
• Transplant Surgery
• Minimally Invasive Surgery

Background:

• Laparoscopic transperitoneal donor nephrectomy (LapDN) presents technical challenges, raising concerns about allograft quality.
• Live donor kidney procurement methods impact graft outcomes and donor safety.

Purpose of the Study:

• To compare anatomical and functional outcomes of kidneys procured via laparoscopic donor nephrectomy (LapDN) versus open donor nephrectomy.
• To evaluate the impact of surgical approach on allograft quality and recipient renal function.

Main Methods:

• Randomized controlled trial involving 60 live kidney donors comparing open and laparoscopic procurement.
• Assessment of donor demographics, operative parameters (e.g., operative time, warm ischemia time), and anatomical vessel length.
• Comparison of recipient acute rejection rates and renal function post-transplantation.

Main Results:

• Laparoscopic donors had longer operating times and initial warm ischemia, but total warm ischemia time was comparable to open donors.
• No significant differences were observed in left or right renal vessel lengths between the two groups.
• Recipient outcomes, including acute rejection rates and renal function, were similar regardless of procurement method.

Conclusions:

• Laparoscopic donor nephrectomy yields kidneys structurally and functionally equivalent to those obtained through open surgery.
• The findings suggest LapDN is a viable alternative, potentially alleviating concerns regarding its effect on live donor kidney quality.
