[Quality control in urography with iopamidol and iohexol. A parallel comparison]
La Radiologia Medica
|March 1, 1987
Summary
Iohexol and iopamidol are contrast media for urography. A study found both provide good image quality without significant differences in excretory pathway distension for patients with normal kidney function.
Area of Science:
- Radiology
- Nephrology
- Urology
Background:
- Iohexol's higher osmolarity may enhance diuretic effects and excretory pathway distension compared to iopamidol.
- Urography is a key diagnostic tool for evaluating the urinary tract.
Purpose of the Study:
- To compare the efficacy of iohexol and iopamidol in urography.
- To assess differences in excretory pathway distension and image quality between the two contrast agents.
Main Methods:
- A comparative trial involving 100 patients with normal renal function.
- Two groups of 50 patients each received either 50 ml (15 gI) of iopamidol or iohexol for urography.
Main Results:
- No significant differences were observed in evaluated parameters including nephrography, calyces, pelvis, ureters, and bladder.
- Both iopamidol and iohexol facilitated the performance of good quality urographies.
Conclusions:
- Iohexol and iopamidol exhibit comparable performance in urography for patients with normal renal function.
- Neither contrast agent demonstrated a significant advantage in terms of excretory pathway distension or image quality.
