Abstract:
Doppler sonography is nowadays considered as a "first step" tool for diagnosis of vascular complications in kidney transplantation. Quite recently, it has been sometimes considered useful and effective investigation in order to obtain information about parenchymal dysfunctional pathologies, particularly about acute rejection. This has been obtained by studying the variation of resistive indexes. The goal of the following investigation was compare Doppler sonography data and histological examination in 50 kidney transplanted recipients in whom the renal biopsy was performed on a clinical basis. In the Authors' experience. Doppler sonography and study of the resistive index does not offer any reliable help in differentiating acute rejection from cyclosporine A toxicity.
