title: [Unilateral catheterless determination of kidney function in hydronephrosis].
abstract: Whereas the value of quantitative separate determination of kidney functioning is undisputed for most urological and nephrological problems, its value for the judgement of hydronephrotic kidneys is doubted by various working groups. Using 15 mongrel dogs, the nuclide excretion at certain times, various calculation intervals and the results of separate functional analysis of hydronephrotic and non-hydronephrotic kidneys were compared. Due to the early nuclide excretion with an advanced secretion peak it is no longer acceptable to use a 2-minute calculation interval for hydronephrotic kidneys in dogs. If the upper limit of the calculation interval is prior to the secretion peak, there will be no overestimation of the hydronephrotic kidneys.
