[Pharmacoechography]

Ultrasonic scanning of the kidney was conducted in the presence of drug-induced polyuria in order to detect upper urinary urodynamic disorders and termed "pharmaco-echography". Pharmaco-echography with furosemide enables an indirect assessment of functional capacity and reserve potentials of the kidneys and the upper urinary tract, and detect a latent functional insufficiency. Detection of upper-urinary urodynamic disorders, using this method, makes possible timely treatment, thus preventing the development of disease. Pharmaco-echography with furosemide, combined with roentgenologic investigation in urologic patients provides an assessment of the events occurring in the upper urinary tract as well as the latter's performance and reserve potentials.
