Dr. Benfield is a member of The North American Pediatric Renal Trials and Collaborative Studies (NAPRTCS) which is a research effort organized in 1987. NAPRTCS’ goal is to register and follow greater than 80% of the children receiving renal transplants in North America, to study the clinical course and natural history of patients with renal dysfunction and to continue following these patients as they move among the end-stage renal disease (ESRD) therapeutic modalities.  Click here to visit NAPRTCS website.
