Hello,
I didn't hear back from you to update the missing information.
Assuming that all other causes of ascites have been eliminated (which is imperative), then one could call this nephrogenic ascites, or ascites that occurs in patients on dialysis - since to imply the kidneys generate it when they are not functioning, does not seem appropriate. Unfortunately, there are no good treatments for it. Aggressive dry weight reduction may actually only serve to cause hypotension, particularly if the patient has low albumin.
Sorry I cannot be of greater help.
