[The role of intravenous urography in the diagnosis of urinary tract lithiasis in the era of new therapeutical methods].

Urinary stones continue to be an interesting and major problem for both urologists and radiologists. The authors try to present the imaging diagnosis possibilities for this pathology according to the expectations of the urologists who have to deal with urinary tract lithiasis with the new methods (extracorporeal shock wave lithotripsy, percutaneous nephrolithotomy, and ureteroscopy). Helical CT has certain advantages and in different centers in Europe appear to be less expensive than intravenous urography (IVU), but unfortunately, is not available in our medical center. So, for us, IVU remains the basic investigation for urinary stones. Echography helps a lot for correct strategy, but together with KUB cannot replace IVU if we want to avoid mistakes.
