Water, urea, sodium, chloride, and potassium transport in the in vitro isolated perfused papillary collecting duct

Abstract

In this article, our objective is to analyze transepithelial transport of sodium, chloride, potassium, urea, and water in the PCD and to describe some studies done in our laboratory illustrating the application of renal tubule perfusion in vitro to the examination of transtubular transport.
