health.kidney-stone-risk Calculator
Calculates kidney stone recurrence risk score from 24-hour urine calcium, oxalate, citrate, uric acid, and volume. Hypercalciuria (>250 mg/day in women, >300 mg/day in men) is the most common metabolic abnormality in stone formers, present in 40–60%.
Inputs
Urine Calcium Mg Day
Reference formula or conversion factor shown for context.
Urine Oxalate Mg Day
Reference formula or conversion factor shown for context.
Urine Volume L Day
Three-dimensional space occupied (m³ or L). 1 m³ = 1,000 L.
Urine Citrate Mg Day
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
risk score (0-9)
Numerical risk rating — higher typically indicates greater probability of an adverse outcome. The score is only as reliable as the inputs and model assumptions.
risk level
The measured or computed level on the applicable scale.
CaOx supersaturation index
How close the system is to its capacity limit. Above 80% sustained saturation typically leads to queuing and latency spikes.
urine volume target
The computed three-dimensional volume.
citrate status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
