AbstractAbstract
[en] This paper is devoted to the analysis of a problem in the field of renal physiology which has shown many new developments during the course of the last few years. The following are treated successively: a) the data obtained from measurements of free water clearance and their interpretation; b) the data provided by nephron morphology and the comparative anatomy of the kidney ; c) the data relative to the existence of an intrarenal osmotic gradient; d) the principle of concentration multiplication by a counter current technique; e) the present day theory of counter current concentration of urine, and f) the physiological check on dilution and concentration mechanisms in urine. Lastly, the advantages of the modern theory and the unknown factors which remain are discussed. (authors)

Cette revue de question est consacree l'analyse d'un probleme de physiologie renale qui, au cours des dernieres annees, a subi un developpement et un renouveau remarquables. Sont successivement exposes: a) les donnees fournies par les mesures de clearance de l'eau libre et leur interpretation; b) les donnees fournies par la morphologie des nephrons et l'anatomie comparee du rein; c) les donnees concernant l'existence d'un gradient osmotique intrarenal; d) le principe de multiplication de concentration par contrecourant; e) la theorie actuelle de concentration de l'urine par contre-courant, et f) le controle physiologique des mecanismes de dilution et de concentration de l'urine. Les avantages de la theorie moderne et les obscurites qui subsistent sont enfin discutes. (auteurs)Original Title
