A Radiology Pathway
In NHS Lothian, GPs have Direct Access to CT KUB for the expedited urgent investigation of symptomatic patients with unilateral loin pain and a suspected diagnosis of acute renal colic. The aim of this service is to aid management by providing an early diagnosis for symptomatic patients, who might otherwise need to be referred as an emergency. Eligible patients will be scanned as soon as practicably possible. This service is not for the investigation of patients who have more non-specific symptoms.

Who To Refer:
CT KUB can be requested for patients:
- Who have symptoms of unilateral renal colic
- Who do not require admission
- Who are male (any age), or female >40 years
Microscopic haematuria is not a prerequisite for CT KUB. A good history is.
For all Radiology requests: Referrers accept responsibility for dealing with the result(s) and informing the patient as necessary.
Who Not to Refer:
- Patients whose pain is uncontrolled with diclofenac, paracetamol and dihydrocodeine – these patients should be referred as an emergency via Flow Centre; or if proven stones and under follow up with Urology, refer to on-call Urology team.
- CT KUB is not indicated for vague symptoms, general abdominal pain, or pain not consistent with stone disease.
- Female patients <40 years. Women <40 yrs with acute loin pain are much less likely to have stones, and more likely to have other pathology (e.g. pyelonephritis, ovarian cyst), so should be referred for US renal tract and pelvis as per the guidance under Urology Loin Pain
- Patients with a known history of stones. Patients should be referred back to the Scottish Lithotriptor Centre urgently (SCI Gateway referral to urology), who will arrange imaging tailored to the patient (CT KUB is not routinely necessary for these patients, who are at risk of a significant cumulative radiation dose as a result of repeated stone episodes).
How To Refer:
Via SCI Gateway, please mark requests as urgent:
- RIE > Clinical Radiology > LI Radiology CT (KUB only)
- SJH > Clinical Radiology > LI Radiology CT (KUB only)
- WGH > Clinical Radiology > LI Radiology CT (KUB only)
Information required for the SCI Gateway referral:
Details of previous imaging
Reasons for request (free text)
Side, duration, and severity of symptoms
CT Practicality and Safety questions: LMP / DM? / Latex Allergy? / Impaired Renal Function? (please provide details in reasons for request box) / Patient weight >20 stones
