OBJECTIVE: To determine whether knowledge about the degree of radiopacity of the double-J ureteral catheters utilized in Spanish hospitals suffices for correct radiologic control and subsequent follow-up.
METHODS: The CT attenuation index was utilized to determine the degree of radiopacity of 23 double-J ureteral stents, comprised of different biomaterials and from different manufacturers, that are used in Spanish hospitals.
RESULTS: The values ranged from 1,000-3,070 Hounsfield units.
CONCLUSION: All the catheters analyzed were sufficiently radiopaque to permit good radiologic control during insertion and subsequent follow-up. The radiopacity of the stent depends on the metal salt employed during the manufacturing process and not on the biomaterial.
