Time to Excretion of Contrast, a Maastricht Prospective Observational Study

NCT04603261 · Status: WITHDRAWN · Type: OBSERVATIONAL

Last updated 2023-10-19

No results posted yet for this study

Summary

Risk of contrast-induced kidney injury is expected to be strongly correlated with exposure time. Studies on the excretion of iodinated contrast material are few and have mostly been carried out in patients with normal renal function. Although case wise reports of persistent renograms have been published, it is not known how long contrast is retained before excretion in patients with eGFR \<30 mL/min/1.73m2, nor which of these patients are most susceptible to contrast retention. The current observational study aims to compare contrast elimination time and % contrast excretion in patients with eGFR \<30 mL/min/1.73m2, to matched patients (for age, sex and contrast procedure type) with eGFR 30-59 and eGFR \>=60 mL/min/1.73m2.

Contrast concentration in urine

Iodinated contrast content of urine samples, collected post-contrast over a period of 5 days at all times of natural excretion within that period, will be assayed. Serum creatinine will be measured daily before (day 0) and during 5 days post-contrast, and again at 1 month post-contrast.
