[Kidney radionuclide diagnosis in the evaluation of clinical problem cases in pediatrics and nephrology].

An internistically and nephrologically as well as paediatrically well preexamined and selected group of patients in particular cases needs for the judgment of the renal function and capacity a nuclear-medical diagnostics which passes these preexaminations. Renal sequence scintigraphy including the trend scintigraphy and examinations of the renal clearance with side-separated judgment of the renal clearance with side-separated judgment of the function are at our disposal. The indication of these techniques and the value of evidence are demonstrated with the help of problem cases. As problem cases are demonstrated a child with glomerulonephritis, a female patient with renal failure post partum before and after haemodialysis including the observation of the course a female patient with localized inflammatory disease as well as a patient with kidney tumour and cirrhosis of the kidney. It is shown that nuclear-medical techniques recognize relatively discrete, but also severe pathological changes and are necessary within a complex judgment of the function, the quantitative establishment of the functional and compensatory capacity of the kidneys as well as for the planning of therapy and the control of the course.
