Renal tubular acidoses (RTAs) are a subset of non-anion gap metabolic acidoses that result from complex disturbances in renal acid excretion.  In a Core Curriculum recently published in AJKD, Ryan Bonner and Gerald Hladik discuss the disturbances that can lead to the development of metabolic acidosis and/or a failure to compensate fully for other systemic acidoses. AJKDBlog’s Interviews Editor, Timothy Yau (@Maximal_Change) sat down with Drs. Roger Rodby (@NephRodby) and William Whittier (@TWhittier_RUSH) to discuss physiology, treatment, and to delve into thoughts on the urinary anion gap.
