Evaluation of 14C-urinary excretion and its comparison with 14CO2 in breath after 14C-urea administration in Helicobacter pylori infection

Objectives: 1) to estimate levels of 14 C-urinary excretion in Helicobacter pylori-infected and noninfected patients after 14 C-urea ingestion, 2) to compare 14 C-urinary excretion and 14 CO 2 breath results with biopsy findings, and 3) to find out correlation between 14 C-urinary excretion with 14 CO 2 breath results, if any. Methods: Twenty-four-hour 14 C-urinary excretion was measured in 26 patients of non-ulcer dyspepsia after oral administration of 5 μCi 14 C-urea to each patient
