x402
magent STONE Nephrolithometry Score (Okhunov 2013) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the Okhunov 2013 STONE nephrolithometry score (sum 5–13) from five caller-assigned PCNL complexity parameters: stone size, tract length, obstruction, calyces involved, and stone density.

How this service works
Okhunov 2013 STONE nephrolithometry for kidney calculi (PCNL). Caller-assigned published item points: size 0_399 1 / 400_799 2 / 800_1599 3 / ge_1600 4 (mm²); tract le_100 1 / gt_100 2 (skin-to-stone mm); obstruction none_or_mild 1 / moderate_or_severe 2 (hydronephrosis); calyces 1_or_2 1 / 3 2 / staghorn 3; essence le_950 1 / gt_950 2 (HU). Sum 5-13. No published SFR bands. Not the Moore 2014 ureteral STONE score. magent does not measure CT. Not a medical device. Not a PCNL order.
Output
Returns the STONE nephrolithometry total score (integer 5–13) reflecting PCNL complexity, along with individual component scores for stone size, tract length, obstruction, number of calyces, and stone density (essence). Higher scores indicate greater surgical complexity.
Example use cases
Preoperative PCNL complexity assessment
“I need the STONE nephrolithometry score for a patient with a stone area of 800–1599 mm², a skin-to-stone distance of 90 mm (so ≤100 mm), none or mild hydronephrosis, only 1 or 2 calyces involved, and stone density of 800 HU (≤950 HU).”
High-complexity staghorn calculus scoring
“What's the STONE score for a staghorn kidney stone with size ≥1600 mm², tract over 100 mm, moderate-to-severe obstruction, and density above 950 HU?”
Low-complexity small stone evaluation
“Can you run the Okhunov STONE nephrolithometry score for a small stone — size under 400 mm², tract ≤100 mm, no obstruction, only 1 or 2 calyces involved, and HU ≤950?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/stone_nephrolithometryWhen to prefer
Use this endpoint when you need to programmatically compute the Okhunov 2013 STONE nephrolithometry score for PCNL case complexity classification. It is specifically the kidney stone PCNL scoring system, not the Moore 2014 ureteral STONE score. Choose this over manual calculation when integrating nephrolithometry scoring into a clinical decision-support workflow, EHR automation, or urology research pipeline.
Side effects
- Missing required query parameter (size, tract, obstruction, calyces, or essence) returns an error
- Invalid enum value for any parameter returns a validation error
- Network or server error returns a non-2xx HTTP status
