How this service works
Moore 2014 STONE score for ED prediction of uncomplicated ureteral stone. Table 3 integer points: sex female 0 male 2; timing gt_24h 0, 6_to_24h 1, lt_6h 3; origin black 0, nonblack 3 (caller-assigned as used in Moore 2014; magent does not assign race); nausea none 0, nausea_alone 1, vomiting 2; hematuria absent 0, present 3. Sum 0-13; 0-5 low, 6-9 moderate, 10-13 high. Not a CT order or stone diagnosis. Not S.T.O.N.E. nephrolithometry.
Output
Returns the total STONE score integer (0–13) along with the risk category (low: 0–5, moderate: 6–9, high: 10–13) and the individual point contributions for each of the five variables (sex, timing, origin, nausea, hematuria).
Example use cases
ED triage for suspected kidney stone
“I'm seeing a female patient in the ED, nonblack, whose pain started about 10 hours ago, she has nausea but no vomiting, and her urine dipstick is positive for blood — can you run the STONE score and tell me if she's low, moderate, or high risk for a ureteral stone?”
Male patient with acute onset flank pain
“Male patient, nonblack, pain onset less than 6 hours ago, vomiting present, hematuria on dipstick — what does the STONE score come out to and what risk tier is that?”
Low-acuity stone rule-out in ER
“I have a Black female patient in the ER whose pain has lasted more than 24 hours, no nausea, no hematuria on dipstick — compute her Moore 2014 STONE score so I can see if she falls in the low-risk group.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/stone_scoreWhen to prefer
Use this endpoint when you need a fast, deterministic, published-formula implementation of the Moore 2014 STONE score for emergency department ureteral stone risk stratification. Prefer it over manual calculation to avoid arithmetic errors and over general LLM reasoning when auditability and exact Table 3 integer scoring fidelity are required. Do NOT use for S.T.O.N.E. nephrolithometry scoring, CT ordering decisions, or definitive stone diagnosis.
Side effects
- Missing any of the five required query parameters returns a 400/422 error
- Invalid enum values (e.g. 'male2' instead of 'male') return a validation error
- Score is a deterministic arithmetic result — no probabilistic or model-based failures
- Result is not a CT order recommendation and should not be interpreted as a stone diagnosis
