Application of the metallic stents in the interventional uroradioligy is the result of continous development of the new generation methods percutaneous nephrostomy (PCN), ballon catheter dilatation (BCD), methal and covered stent application. Application of metal stents in the renal canal system was attempted in order to eliminate BCD and PCN--related limitations as well as poor therapeutic results of these methods in a number of etiopathogenic groups of urinary stasis. Years--long application of interventional uroradiology methods, until the development of metallic stengts had shown the following therapeutics facts: PCN is incapable to resolve the caus of urinary obstruction. Permanent good therapeutic BCD results mostly depend on pathohistological aspect of the stricture, metallic stents are most frequently the last choice in therapeutics approch to urinary tract obstructions and their application is directly dependent on previous therapeutics results accomplished by PCN and BCD. In therapeutical sequences new generation of covered stents have important place as method of selection in patients of irreversibile uroopstruction of distal ureter.
