Summary

Prospective single centre study aiming at validating a conditional imaging strategy for diagnosis of suspected kidney stone.

Consecutive Emergency department patients referred to the medical imaging department for exploration of a suspected acute uncomplicated renal colic will undergo the following interventions : systematic plain abdominal Xray, systematic ultrasonography and systematic unenhanced CT (with a reduced dose scan), in addition to clinical examination and assessment of body mass index and the Sex, Timing, Origin, Nausea, Erythrocytes (STONE) clinical prediction score for symptomatic stone.

Patients will be followed up at 1 month to record the need for urologic intervention and its type.

The performances of different conditional imaging strategy for the diagnosis of suspected renal colic will be assessed retrospectively. The conditional strategies tested will be based on the patient's stone score and BMI and targeted use of combined plain X-ray and ultrasonography and/or unenhanced CT.

The reference diagnosis for renal colic will be made according to the finding of a ureteral stone or indirect signs of urolithiasis at unenhanced CT.

Conditions

  • Acute Renal Colic
  • Nephrolithiasis

Interventions

DEVICE

Diagnostic imaging modalities for suspected renal colic

All patients with suspected acute uncomplicated renal colic included will undergo ultrasonography in addition to unenhanced CT of pelvis and abdomen and plain X-ray of the abdomen. Imaging examination will be performed according to current guidelines. Ultrasonography study and colour doppler will include the kidney, ureterovesical joint and ureters. Unenhanced CT will be performed using a dedicated low-dose protocol.
