Clinical Score Application for Abdominopelvic Computed Tomography Used in the Diagnosis of Renal Colic Patients

Abstract

Abstract Background To develop risk scoring for the use of computed tomography (CT) imaging using the visual analog scale (VAS), physical examination, and laboratory findings of renal colic patients admitted to the emergency department (ED). Materials and Methods This is prospective observational study. Among the patients who presented to the ED with abdominal or flank pain, patients who were scheduled for CT imaging for urolithiasis were included in the study. The mean VAS pain scores, physical examination findings, laboratory parameters, and macroscopic and microscopic values in urinalysis were compared between the two groups with and without stones on CT. Results Of the 196 urolithiasis patients included in the study, 165 had ureteral stones, 76 had renal stones, and 45 had renal and ureteral stones. While the difference between the urine erythrocyte averages of the two groups was borderline significant (p = 0.04), there was a high difference between the urinary hemoglobin amounts (p < 0.001). In patients with urinary system stone disease, hydronephrosis, and ureteral dilatation, hemoglobin ++ and above were more significant (p < 0.001). For ureteral stones, pain intensity increased as the size increased (r = 0.34 p < 0.001). White blood cells > 10,000 103/mL, and C-reactive protein (CRP) ≤ 5 mg/L were more significant in patients with acute renal colic. Conclusions Although we cannot develop a clinical scoring system for renal colic patients, the meaningful results we found for urinary stone disease can be used in a newly developed scoring system. It can be used in new scoring systems in the ED using a high VAS score, presence and amount of urine hemoglobin, CRP) ≤ 5 mg/L, and creatinine value.
