"The most common placement for a renal transplant has been in the extraperitoneal/retroperitoneal space, confined anteriorly by the peritoneum, posteriorly and laterally by pelvic muscles. Occasionally, increased pressure in this relatively tight space may lead to compression of the transplant and if there is sufficient pressure this might lead to ischaemia of the transplant. It seems more common with large allografts and some surgical techniques."
