Continuous ambulatory peritoneal dialysis is a new dialysis technique. It is unknown at this time which patient would be served best by this therapy. Two cases of dialysis-related ascites were successfully treated by this technique. We suggest that the continuous control of salt and water balance possible with this technique, as well as frequent drainage of the peritoneal cavity to prevent fluid reaccumulations, contributed to successful treatment. Continuous ambulatory peritoneal dialysis may be used to treat dialysis-related ascites.
