Spontaneous dialytic ultrafiltration with intraperitoneal reinfusion of the concentrate in 15 cirrhotic patients with intractable ascites.

The clinical efficacy and tolerance of dialytic ultrafiltration of ascites through a hemofilter (DUF) with peritoneal reinfusion of the concentrate was evaluated in 15 cirrhotic patients with intractable ascites. All together, 51 DUF procedures were carried out. An average of 8.6 was ultrafiltered during 12 h with no significant change in blood pressure, hemoglobin, coagulation parameters or plasma creatinine. A significant increase in ascitic protein concentration was observed immediately after the procedure and a slight but significant increase in 24 h urinary output. A controlled evaluation of DUF compared to large paracenteses seems to be justified by these preliminary results.
