Noninfectious complications of peritoneal dialysis (PD) remain an important impediment to successful implementation of PD. Rare noninfectious complications of the PD catheter are sparsely reported. We report an unusual complication of outflow failure due to a peritoneal catheter that separated into two distinct intra-abdominal segments, due to an unusual method of placement in which two catheters were connected to make a long intra-abdominal portion to permit a high exit site on the abdominal wall. The application of this unusual rather a unique technique led to separation of the two catheter portions and the outflow failure shortly after the patient started continuous ambulatory PD. We reviewed other unusual causes of PD catheter failure, and these included luminal stones blocking the PD catheter, pneumomediastinum related to inappropriate technique, catheter deformation and leak due to the use of antibiotic ointment at the exit site of polyurethane catheters, vesicoperitoneal fistula and perforation of the bladder from the placement of PD catheters, rare site migrations of the catheter, and subcutaneous titanium connector infection in a presternal catheter. Knowledge of these unusual complications may allow prevention and/or early recognition.
