ACUTE REACTIONS TO UROGRAPHIC CONTRAST MEDIUM

Acute reactions to urographic contrast media.

A prospective study of 3509 consecutive patients examined by excretion urography has been conducted to assess the incidence and significance of the untoward effects of urographic contrast media. Four compounds were used in doses containing 160 to 500 mg iodine/kg body weight. Toxic effects, arm pain, and allegic reactions were assessed separately, while the remainder were classified according t...

A comparison of the clearance of urographic contrast medium (sodium diatrizoate) by peritoneal and haemodialysis.

1. The clearance of isotopically labelled sodium diatrizoate by haemodialysis was measured in vitro, with simulated extracellular fluid, and in vivo in eleven patients, at varying rates of fluid or plasma flow. Clearance was also measured in five patients undergoing peritoneal dialysis. In all instances simultaneous measurements of urea clearance were made and the diatrizoate/urea clearance rat...

Contrast Medium-Induced Acute Kidney Injury.

Contrast medium-induced acute kidney injury (CI-AKI) is a predominant cause of hospital-acquired renal insufficiency. With an increasing number of contrast medium-enhanced radiological procedures being performed in a rapidly increasing ageing population in the Western world, it is imperative that more attention is given to understand the aetiology of CI-AKI to devise novel diagnostic methods an...

Fifty per cent urokon sodium as an intravenous urographic contrast medium; a study based on 250 cases.

I urography is a safe, relatively simple procedure that offers much valuable information about the form and the functioning of the urinary tract and its neighboring structures. For these reasons it frequently is employed as a diagnostic measure. Although several commercially available contrast media give good visualization of the urinary tract and cause few postinjection reactions, new preparat...
