Failure of peritoneal dialysis (PD) immediately following soft catheter insertion is well recognized and may be manifest by dialysate leakage, early peritonitis, or early inadequate outflow (1,2), the latter of which requires catheter replacement in up to 50% of cases (1). We describe 3 infants with failure of continuous cyclic peritoneal dialysis CCPD) following PD catheter insertion, as a result of poor dialysate outflow. In each case adequate dialysis was achieved using tidal PD.
