Prophylactic peritoneal fenestration to prevent morbidity after kidney transplantation: a randomized study

Area of Science:

• Nephrology
• Transplant Surgery
• Surgical Complications

Background:

• Lymphocele, a common complication after kidney transplantation, involves lymphatic fluid accumulation.
• This study investigates prophylactic fenestration as a preventative measure.

Purpose of the Study:

• To evaluate the efficacy of prophylactic peritoneal fenestration in preventing lymphocele formation post-kidney transplantation.
• To compare the incidence of symptomatic lymphoceles and subsequent treatments between fenestration and standard surgical groups.

Main Methods:

• An open randomized trial involving adult kidney transplant recipients from deceased donors.
• Patients were randomized to either prophylactic peritoneal fenestration or standard surgical procedure.
• Symptomatic lymphocele incidence was assessed at 1 year, with ultrasound monitoring in the early postoperative weeks.

Main Results:

• The fenestration group (3.0%) had significantly fewer symptomatic lymphoceles than the standard group (15.5%) (RR=0.20, P=0.015).
• Fewer invasive procedures were required for lymphocele treatment in the fenestration group.
• Early postoperative fluid collections were more prevalent in the standard group (66% vs. 37%).

Conclusions:

• Prophylactic fenestration is effective in reducing lymphocele risk and the need for invasive treatments.
• Further studies are recommended in populations using lower steroid doses and wound drains.
