Iohexol vs. diatrizoate. A comparative study in intravenous urography.
Investigative Radiology
|January 1, 1985
Summary
Iohexol demonstrated superior safety and efficacy compared to diatrizoate in intravenous urography. This nonionic contrast medium resulted in significantly more excellent imaging studies with fewer adverse reactions.
Area of Science:
- Radiology
- Medical Imaging
- Pharmacology
Background:
- Intravenous urography is a key diagnostic tool.
- Assessing the safety and efficacy of contrast media is crucial for patient outcomes.
- Iohexol and diatrizoate are commonly used contrast agents.
Purpose of the Study:
- To compare the safety, incidence of adverse side effects, and efficacy of iohexol versus diatrizoate in intravenous urography.
- To evaluate image quality and patient tolerance.
Main Methods:
- A randomized, double-blind study involving 435 patients across nine centers.
- Systematic monitoring of hematologic, biochemical, blood pressure, and pulse parameters.
- Detailed recording of side effect severity, nature, and duration.
- Radiographic image quality assessment at multiple time intervals post-injection.
Main Results:
- Iohexol yielded a significantly higher number of excellent quality urography studies compared to diatrizoate.
- Iohexol exhibited a remarkably low incidence of side effects and adverse reactions.
- No significant differences were noted in hematologic or biochemical parameters between the two agents.
Conclusions:
- Iohexol is a safe and suitable nonionic contrast medium for intravenous urography.
- Iohexol offers improved image quality and patient safety over diatrizoate.
- The findings support the use of iohexol in routine urographic procedures.
