Patients with advanced chronic kidney disease nearing dialysis but without pre-established access almost uniformly initiate dialysis with a temporary central venous catheter. These catheters are associated with high rates of infection and flow disturbances, requiring removal and subsequent replacement. Many of these patients might be candidates for peritoneal dialysis (PD), but because of the absence of prior catheter placement, the default initial modality is hemodialysis. Recent reports, however, have demonstrated the feasibility of initiating PD urgently despite the late referral for access placement. Urgent-start PD clinical pathways require a unique infrastructure and treatment approach. This article reviews the salient features required to establish an urgent-start PD program.
