although a direct relationship between the prostaglandin excretions of pge2 and pgf2 alpha and avp does not seem to exist , it is possible that the higher prostaglandin excretion in the renal transplant recipients may be a counterbalancing mechanism to the higher avp level , which most likely is secondary to a decreased responsiveness to vasopressin of the renal collecting ducts in the transplanted kidney .
