Abstract
Peritoneal dialysis (PD) enjoyed huge growth in the 1980s, followed by a rapid decline in the late 1990s, and a now persistently low utilization rate in many countries, including the United States. Recent clinical data indicate a survival advantage for patients started on PD. Residual renal function is better preserved with PD. Adequacy targets are being revised and will likely allow PD prescriptions to be simplified. The physiology of the peritoneum is better understood and treatment strategies reflect that understanding. New solutions have been developed in response to studies that have assessed the impact of conventional PD dialysate on the structure and function of the peritoneum. A remaining challenge is to ensure that nephrology trainees and nephrologists in practice are fully informed of the advantages of PD for many patients and of the advances in the therapy. If this can be achieved, PD should start to grow again.
