[Physiological-pathophysiological evaluation of possibilities and limits of unilateral renal function tests].

1. Issuing from the clinical method of proceeding in side-separated diagnosis of the renal function under theoretical aspect a survey orientation for the renal global function is tried. 2. The method orientation is done according to semiquantitative and quantitative valuation. The isotope and contrast remedy urography, the functional tests after Howard, Rapoport and Stamey, the conventional side-separated estimation of the clearance, the isotope sequence scintigraphy as well as the diagnostics of the renal and intrarenal haemodynamics (renin determination, measuring of the renal plasma flow by means of PAH and other indicators [133-xenon-wash-our-technique]). 3. Finally a valuation of the method concerning the side-separated diagnostics of the renal elimination function as well as of the stenosis of the renal arteries is done taking into consideration the performability of the investigation methods in the clinic.
