Abstract

Background: Urolithiasis is a common urinary tract disease that can lead to obstruction, infection, and renal function impairment. Therefore, selecting an appropriate imaging modality is crucial for early detection and treatment planning. Objectives: To describe the clinical and laboratory characteristics and compare the diagnostic performance of different imaging modalities in detecting renal stones. Materials and methods: A cross-sectional descriptive study was conducted on 175 patients with renal calculi, confirmed by contrast computed tomography (CT) of the urinary system. Results: The mean age of the patients was 50.45 ± 10.72 years, with males accounting for 54.9%. Dull flank pain was the most common symptom, while most laboratory parameters were within normal limits. The upper calyx was the most frequent stone location (53.7%), bilateral stones accounted for approximately 7%, and a solitary stone was found in 69.1% of cases. Renal ultrasonography detected stones in 97.1% of patients, which was higher than plain abdominal radiography (87.4%). The mean stone size measured on ultrasonography was 1.79 mm smaller compared to that obtained from CT imaging. Conclusion: Ultrasonography detected a greater number of renal stone cases compared with plain abdominal radiography (KUB). The stone size measured by ultrasonography showed good agreement with computed tomography (CT) measurements, with only a small and clinically acceptable difference.
