    Computed tomography (CT) is generally used for ureteral stone diagnosis. Unnecessary imaging use should be reduced to prevent increased radiation exposure and lower costs. For this reason, scoring systems that evaluate the risk of ureteral stones have been developed. In this study, we aimed to investigate the diagnostic accuracy of the modified STONE score (MSS) and its ability to predict ureteral stones. The research was conducted as a multi-center, prospective and observational study. Patients aged 18 and over who presented to EDs with complaints of flank pain and who received a CT were included. Patients were divided into two groups based on the presence or absence of stones, and the categories of the MSS were determined. The ability of the MSS to predict the ureteral stone and its diagnostic accuracy were calculated. The median age (min/max) of the 367 study patients was 37 (18/91), and 244 (66.5%) were male. A ureteral stone was present in 228 (73.0%) patients. Male gender, previous stone history, duration of pain less than 6 h, presence of hematuria, and CRP value below 0.5 mg/dL were significantly more common in the group with stones. The prevalence of ureter stones in the MSS high-risk group was 96.0%. The area under the receiver operating characteristic curve and sensitivity of the MSS was 0.903 and 0.81, respectively. The modified STONE score has high diagnostic performance in suspected urinary stone cases. This scoring system can assist clinicians with radiation reducing decision-making.
