There was no statistically significant differences in interpretation of the CT findings between those with and without the delayed bladder phase scan (P = .063, 95% CI 0.962 - 0.997). </p><p><strong>Conclusion:</strong> The delayed bladder phase scan had no significant yield in follow-up CT whole abdomen of non-urinary tract cancer patients who had no urinary tract symptoms.</p> ER -
