Should peritoneal dialysis catheters be removed at the time of kidney transplantation?

: Delayed graft function (DGF) following transplantation necessitates support in the form of hemodialyis (HD) or peritoneal dialysis (PD). However, post-transplant PD-related complication and failure rates are unknown.

: We studies patients who were on PD at the time of kidney transplantation over a 4-year period at two separate institutions.

: Of the 137 PD patients, 19 had their catheters removed at the time of transplant. Of the remaining 118 patients, 89% had immediate graft function. PD-related complications in this group included peritonitis (n=5), catheter-related infections (n=2) and emergency laparotomy (n=1). Of the 15 patients requiring post-transplant PD, 33% developed peritonitis and 20% had fluid-leaks necessitating HD. Overall, leaving a PD catheter in situ post- transplantation is associated with 7% rate of peritonitis versus 0% if removed (p < 0.05).

: PD catheter removal should be considered at the time of renal transplantation, as postoperative PD-related failure/complication rates are high.
