Methodology · worked example, guidelines & full notes
0–5 low, 6–9 moderate, 10–13 high.
When to use
Estimate stone probability in acute flank pain.
How it works
Sex (male 2), Timing (< 6 h 3 / 6–24 h 1), Origin/race (non-black 3), Nausea (vomiting 2 / nausea 1), Erythrocytes/haematuria (3). 0–13.
Key points
- 0–5 low, 6–9 moderate, 10–13 high.
- High scores may reduce immediate CT use.
- Stay alert for serious mimics (AAA, pyelonephritis).

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Sex | Female (0) |
|---|---|
| Duration of pain | 6–24 h (1) |
| Race | Non-black (3) |
| Nausea/vomiting | Nausea alone (1) |
| Microscopic haematuria | Absent (0) |
→STONE5/13
- Probability of stone：Low probability
- Note：Consider imaging and look for alternative diagnoses.

| Duration of pain | < 6 h (3) |

| Nausea/vomiting | None (0) |
| Microscopic haematuria | Absent (0) |
→STONE6/13
- Probability of stone：Moderate probability

FAQ
Frequently asked questions
- What are the limits and cautions when using STONE Score (Ureteral Stone Probability)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does STONE Score (Ureteral Stone Probability) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is STONE Score (Ureteral Stone Probability) calculated in practice? Can you show a worked example?
- Inputs: Sex Female (0), Duration of pain 6–24 h (1), Race Non-black (3), Nausea/vomiting Nausea alone (1), Microscopic haematuria Absent (0) → Result: STONE 5 /13（Probability of stone: Low probability, Note: Consider imaging and look for alternative diagnoses.） Inputs: Sex Female (0), Duration of pain < 6 h (3), Race Non-black (3), Nausea/vomiting None (0), Microscopic haematuria Absent (0) → Result: STONE 6 /13（Probability of stone: Moderate probability, Note: Consider imaging and look for alternative diagnoses.）
