Flow correlation of loop of Henle potassium influx.
Potassium influx in short loops of Henle was assessed using end proximal to early distal perfusion with potassium-free saline. Over a wide range of perfusion rates influx was highly correlated with collected flow rates. The magnitude of the influx was comparable with the delivery rate of potassium to the early distal site seen during free flow, over a narrower range of collected flow rates.
