Vergleichende isotopennephrographische Untersuchungen während der Schwangerschaft und bei hormonaler Kontrazeption

Renal function was investigated by isotope nephrography in 31 pregnant women with normal kidneys during various phases of pregnancy, and in 137 women on continuous contraceptive steroids (up to eight years). The semi-quantitative parameters of zum Winkel were used. It was found that the use of oral contraceptives did not lead to any change in renal function, whereas with advancing pregnancy there was distinct excretion delay on the isotope nephrogram. The results are discussed in the light of the relevant literature. Isotope nephrography appears to be a satisfactory screening test for evaluation of renal function on each side.
