title: [Scintigraphy in chronic micturition disorders].
abstract: Partial functions of the kidney, i.e. renal blood flow, GFR etc, can be estimated with radionuclide techniques as safe and non-invasive methods. Many methods have been published to distinguish between obstructive and non-obstructive hydronephrosis. A simple and highly relevant technique is the diuretic radionuclide urography which should be done in all patients with questionable urographic or sonographic findings. The evaluation of split renal function is somewhat difficult because tissue absorption will influence uptake determination. In hydronephrosis this absorption cannot be predicted by sonographic measurement of the kidney's depth and mass. A solutions is to calculate the absorption in these patients by stepwise scintigraphy. Continuous quality control of the technique is emphasized.
