Abstract

Objectives: To assess the validity of ultrasonography (USG) for detection of renal and ureteric calculi in patients of renal colic by taking computerized tomography (CT) scan as a gold standard.

Study Design: Cross-sectional analytical study.

Place and Duration of Study: KRL General Hospital, Islamabad Pakistan, from Jan to Dec 2019.

Methodology: 110 patients with suspected renal colic presenting in emergency and outpatient departments were recruited through non-probability convenience sampling. Both adult female and male patients irrespective of their age, fulfilling the inclusion criteria were included. Transabdominal USG and unenhanced CT of all patients were performed, and findings were recorded.

Results: CT scan was taken as gold standard and sensitivity, specificity, positive predictive values, negative predictive values, and diagnostic accuracy of ultrasound in detecting renal calculi were 73.08%, 94.83%, 92.68%, 79.71%, and 84.54% respectively. While these values in detecting ureteric calculi by USG were 14.81%, 89.65%, 80%, 27.37% and 34.54% respectively.

Conclusion: Ultrasonography (USG) can be used to identify renal calculi on the x-ray in patients with renal colic, but it is less effective at detecting ureteric calculi. CT is reserved for cases where ultrasonography is unable to provide conclusive results due to the higher costs and ionizing radiation risks.
