The rate of positive urolithiasis and significant alternative diagnoses for the ED patients who underwent CT KUB this institute were comparable to other published studies.3,5 There is statistically significant association between gender and diagnostic yield of urolithiasis, with male predominance. Together with good history taking and clinical assessment, this audit supports the use of CT KUB as the preferred imaging modality for investigation of suspected renal colic with good diagnostic yield. However, it is noted that there is a significant percentage of negative CT KUB in females. Current practice can be further improved by considering other imaging modalities when investigating young female patients with suspected renal colic to avoid unnecessary radiation exposure.
