magent VURx (Kirsch 2014) — Vesicoureteral Reflux Prediction Score
x402
magent VURx (Kirsch 2014) — Vesicoureteral Reflux Prediction Score is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Computes the Kirsch 2014 VURx score (1–6) and its associated spontaneous improvement/resolution probability for children under 2 years with primary vesicoureteral reflux, based on sex, VUR timing, grade, and ureteral anatomy.

How this service works
Kirsch 2014 VURx for children <2 years with primary vesicoureteral reflux. Caller-assigned vur_timing (voiding 1, late filling 2, early- or mid-filling 3), female (1), high_grade grade IV-V (1), and ureteral_anomaly (complete duplication or periureteral diverticulum, 1). Score 1-6. Improvement or resolution: 1 → 89%, 2 → 69%, 3 → 53%, 4 → 16%, 5-6 → 11%. magent does not read a VCUG. Not a medical device. Not a surgery order.
Output
Returns the VURx integer score from 1 to 6 and the associated spontaneous improvement or resolution probability (e.g. score 1 → 89%, score 4 → 16%), derived from the Kirsch 2014 prediction rule for children under 2 with primary vesicoureteral reflux.
Example use cases
Counseling parents on VUR prognosis
“I'm seeing a 14-month-old girl with primary VUR grade V and it's visible during voiding on her VCUG — no ureteral duplication. Can you run the Kirsch VURx score and tell me the probability this will resolve on its own?”
Comparing surgical vs watchful waiting
“For a male infant under 2 with low-grade VUR (grade II) that shows up on late filling during the VCUG and no ureteral anomaly, what does the Kirsch 2014 VURx calculator say about his chance of spontaneous improvement?”
Documenting VURx in clinical notes
“I need the VURx score for a female patient under 2 with high-grade VUR appearing in early-mid filling and a complete ureteral duplication — give me the score and the improvement percentage so I can document it.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/vurxWhen to prefer
Use this endpoint when you need a validated, published clinical scoring tool (Kirsch 2014 VURx) for stratifying spontaneous resolution probability of primary VUR in children under 2. Prefer it over generic risk estimates when you have structured VCUG timing data, sex, VUR grade, and ureteral anatomy. Not appropriate for children ≥2 years, secondary VUR, or when VCUG data is unavailable. Not a substitute for physician interpretation or a medical device.
Side effects
- Missing required query parameters (female, vur_timing, high_grade, ureteral_anomaly) → HTTP 400 or validation error
- Invalid vur_timing value (must be one of: voiding, late_filling, early_mid_filling) → rejection
- Boolean fields passed as non-boolean strings → parsing error
- Network or server error → HTTP 5xx
- Payment not included or insufficient → HTTP 402
