Renal transplantation after prolonged dwell peritoneal dialysis in children.

Thirty-three children received a total of 38 renal transplants (18 living related donor, and 20 cadaveric) after being on CAPD and/or CCPD (PDPD). Ten patients (12 transplants) were converted to hemodialysis pre-transplant in order to be free of the risk of peritonitis and off antibiotics, whereas 23 patients (26 transplants) were on PDPD at the time of transplant. The latter group of patients are described in greater detail. Within this group there was one episode of catheter colonization with Flavobacterium, and only three patients developed ascites post-transplant. Of the 26 transplants, catheters were removed at the time of transplant in the 13 LRD allografts but left in situ for a mean of 3.8 weeks in the 13 cadaveric transplant recipients. Peritoneal dialysis was required post-transplant in seven patients (two LRD recipients requiring a new catheter placement) without complications. Our policy of removing PD catheters at the time of transplant in LRD recipients and prior to hospital discharge in cadaveric transplant recipients has resulted in the avoidance of additional hospitalizations in 19 of the 26 transplants and avoided extra surgery in 11 of the 13 LRD transplants. We conclude that children who have been on PDPD are suitable candidates for renal transplantation and that the early removal of PD catheters, including removal at the time of transplantation in LRD recipients, is associated with a significant reduction in operative procedures for the patients.
