Robot-Assisted Kidney Transplantation: Initial Experience with a Modified Hypothermia Technique

Area of Science:

• Nephrology
• Urology
• Minimally Invasive Surgery

Background:

• Robot-assisted kidney transplantation (RAKT) is an emerging surgical approach.
• Optimizing organ preservation during transplantation is crucial for patient outcomes.
• A modified hypothermia technique was developed to address challenges in RAKT.

Purpose of the Study:

• To evaluate the initial experience and feasibility of RAKT.
• To assess the efficacy of a modified regional hypothermia technique during RAKT.
• To analyze surgical and functional outcomes in patients undergoing RAKT.

Main Methods:

• Twelve patients with end-stage renal disease underwent RAKT.
• A modified regional hypothermia technique involved wrapping the kidney in a sealed plastic jacket with ice slush.
• Surgical data, ischemia times, blood loss, hospital stay, and postoperative serum creatinine levels were analyzed.

Main Results:

• All 12 RAKT procedures were successfully completed without complications.
• Mean operative time was 180.5 minutes; mean console time was 133.3 minutes.
• Mean cold ischemia time was 135.1 minutes; median blood loss was 50 mL; median hospital stay was 9.5 days. All patients and grafts survived at a median follow-up of 32.2 months.

Conclusions:

• RAKT is a safe and feasible procedure for centers with expertise in open kidney transplantation and robotic surgery.
• The modified hypothermia technique effectively maintains constant kidney temperature and prevents paralytic ileus.
• This approach offers a promising alternative for kidney transplantation, enhancing organ preservation and patient recovery.
