Retroperitoneal Compartment Syndrome in Renal Transplantation: How to Salvage the Graft?

Early allograft dysfunction may be caused by several technical factors including vascular complications such as thrombosis, kinking, or extrinsic compression. Renal allograft compartment syndrome (RACS) is an unrecognized cause of early allograft dysfunction. This complication is characterized by increased pressure of the iliac fossa that reduces the blood supply to the graft with a potentially devastating consequence. The main objective when recognizing this condition is to create a tension-free muscle closure. Many approaches have been proposed involving mesh such as the mesh hood fascial closure technique.^1-4 PATIENT AND METHODS: We describe in the video an RACS during an operation. The recipient is a 23-year-old young man with a body mass index of 22, with renal failure secondary to chronic reflux. Past history of failure to peritoneal dialysis currently on hemodialysis. He received a living donor's kidney. After performing a standard anastomosis, his urine output was brisk. The fascia was then closed with no force, at which point he stopped making urine. A RACS was suspected; intraoperative examination and ultrasound showed no flow in the graft, with no signs of kinking. Immediately, reexploration was performed, showing the graft with abnormal color and turgor. After relieving the pressure, the graft returned to normal. The closure was redone with a large ellipsoid piece of polypropylene mesh draped loosely and without tension over the graft.

A Doppler ultrasound, after the skin closure was performed, showed good flow, and the postoperative course was unremarkable. There was minimal bulking in the right iliac area, making it cosmetically acceptable.

RACS could be associated with a lack of compliance in the retroperitoneal cavity.⁵ The RACS required a prompt intervention. The timely suspicion is a watershed in the prognosis of this rare pathology. We propose that mesh hood fascial closure is easy, effective, and a safe method to treat these complications.
