Cystographic contrast media: Clinical and experimental studies

Crysto-Contray II 17.2% (81 mg 1/ml), diluted Cysto-Conray 10% (47 mg l/ml), and Hypaque-Cysto 10% (47 mg l/ml) produced no histologic effects on rat bladders. Simulated ureters in water phantoms were well shown with lower concentrations of cystographic solutions including those of 5% (24 mg l/ml). In clinical studies there was little difference between Cysto-Conray II 17.2% and Hypaque-Cysto 10% for delineating refluxing ureters, bladder margins, and the urethra. Intraluminal filling defects in dog bladders were demonstrated best with cystographic concentrations of less than 10% (47 mg l/ml).
