Conference paper


Potassium metabolism in RCU has received little attention by stone researchers1, despite the fact that potassium forms soluble complexes with oxalate2, and is a key substance in renal acid-base and citrate regulation. In RCU, hypocitraturia and renal tubular acidosis-like hyperbicarbonateuria are well-documented3,4 along with a tendency toward hypokalemia3.
