[Heterolateral renal dystopia (2 cases)]

The authors observed two cases with crossed renal dystopia, to which venous urography, renal scintigraphy, echographic and gamma-chamber investigations were performed. The venous urography, in case of the appropriate symptomatics, is stressed to be able to establish the presence of heterolateral dystopia by as far as the distributional function of the anomaly is concerned--the gamma-chamber investigation is with the highest information value.
