[The scintigraphic effect of extracorporeal lithotripsy: prospective series of 25 cases]. / Le retentissement scintigraphique de la lithotritie extra-corporelle: série prospective de 25 cas.

ABSTRACT

25 patients with non complicated renal stones were treated by extracorporeal shockwave lithotripsy (ESWL) using Sonolith 3000 an electrohydraulic generator type. They were evaluated before, 15 days and 3 months after ESWL by renal scintigraphy, using for 15 of them technetium -99m dimer captosuccinic acid and technetium -99m-diethylene-triamine acetate for the last 10. This follow up scintigraphic study shows no reduction of glomerular filtration rate after ESWL but some focal parenchymal lesions. Very few of these lesions persist at 3 months. These parenchymal damages seem to be less frequent and less persistent than with piezo-electric lithotripter.
