Postoperative ulnar neuropathy after kidney transplantation

Area of Science:

• Nephrology
• Neurology
• Surgical Complications

Background:

• Postoperative ulnar neuropathy is a potential complication following renal transplantation.
• Mechanical trauma to the elbow during surgery is a suspected cause.

Purpose of the Study:

• To investigate the causes of postoperative ulnar neuropathy in renal transplant recipients.
• To identify contributing factors and propose preventative strategies.

Main Methods:

• Retrospective analysis of eight patients who developed ulnar neuropathy post-renal transplantation.
• Examination of surgical positioning (adducted vs. abducted arms), presence of arteriovenous shunts, and blood pressure monitoring techniques.

Main Results:

• Ulnar neuropathy occurred in both adducted and abducted arms.
• Contributing factors included arm position, arteriovenous shunt presence, blood pressure cuff placement, and subclinical uremic polyneuropathy.
• Protective measures for adducted arms and optimized cuff placement for abducted arms were effective.

Conclusions:

• Postoperative ulnar neuropathy in renal transplant patients is multifactorial.
• Implementing specific protective measures during surgery can prevent this complication.
