Methods and materials
Patients who presented to emergency department with suspected renal colic and subsequently underwent CT KUB between 1 October 2017 and 31 March 2018 were identified retrospectively using PACS.
Exclusion criteria includes:
- Urinary tract infection
- Known persisting renal calculus within 6 months prior to the CT KUB
- Follow-up for renal calculus
A 128-slice helical CT scanner performed at 100kV, 35mA and 2.0 mm width was used to scan the patients.
All CT KUB images were either primarily or secondarily reviewed by a consultant radiologist.
The CT KUB reports, patients' follow-up and information regarding interventions in positive cases were obtained from the patients' electronic record and management system.
Ethical approval and patient consent were not required in our institution for this retrospective case series study.
