Nephrogenic ascites. Case report and review of the literature.

Nephrogenic ascites is a clinical diagnosis defined as persistent ascites in an uremic patient without evidence for a causative (specific) underlying disease. The incidence is not known. Contributing mechanisms may include peritoneal membrane changes, fluid overload, hyperparathyroidism, reduced lymphatic drainage, heart failure and hypoproteinemia. Rigid fluid control, intensive hemodialysis, high-protein diet, intravenous albumin infusion, intraperitoneal steroid injections and paracenteses as well as implantation of a peritoneatrial pump have all been found ineffective as treatment. Peritoneal dialysis has been shown to resolve ascites, however, the only effective treatment is so far renal transplantation. The development of nephrogenic ascites is associated with a poor prognosis. Thus, one year after the development of nephrogenic ascites 1/3 had died.
