[Intervention in nuclear medicine kidney diagnosis].

In the present review, the possibilities of ergometric and pharmacological "intervention" with a view to improving the validity of scintirenography are reported. Exercise renography at present does not have a defined role in clinical routine. This procedure, however, gives additional information in hypertensive patients with respect to renal ischemia. Captopril scintirenography can be recommended as a screening test for renovascular hypertension. Furosemide-"intervention" differentiates between obstructive uropathy and dilatation of renal collecting system without obstruction. This is true especially in newborns with congenital abnormalities of the upper urinary tract, in order to stratify these young patients for surgical or conservative treatment.
