title: Comparative study of the methylglucamine salts of iodamide and iothalamate in clinical urography.
abstract: In a comparative urographic study of the methylglucamine salts of iodamide (Uromiro 300) and iothalamate (Conray 280) the following conclusions have been made: (i) In subjects with radiologically normal kidneys and a creatinine clearance greater than 70 ml/min total urogram scores and nephrogram scores were higher with iodamide (not statistically significant). The improvement in performance was more marked in the nephrographic phase. (ii) In patients with radiologically normal kidneys and a spectrum of normal and abnormal renal function, total urogram scores and nephrogram scores showed no significant dependance on creatinine clearance. (iii) No correlations of note were observed between urographic performance and physical or biochemical parameters for either contrast medium. (iv) Side effects encountered in the study were mild and there were no significant differences between the contrast media in either the incidence or severity of the side effects. (v) Post-injection blood pressure profiles showed no significant differences between the media. (vi) Induced electrocardiographic abnormalities were uncommon and mild occurring in seven patients following iothalamate and three patients following iodamide.
