# Licurse 2010 AKI Hydronephrosis Score Calculator

> Licurse 2010 AKI Hydronephrosis Score Calculator 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 Licurse 2010 clinical score predicting hydronephrosis (HN) and hydronephrosis requiring intervention (HNRI) in patients with AKI, based on seven caller-assigned boolean flags.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability licurse-2010-aki-hydronephrosis-score-calculator-21fd26a5
```

Example prompt: Calculate the Licurse 2010 hydronephrosis-in-AKI score for my patient: they have a history of hydronephrosis, are not Black, have no recurrent UTIs, have BPH (obstruction-consistent diagnosis), are not on inpatient nephrotoxins, do not have CHF, and do not have prerenal AKI from pressors or sepsis.

## When to prefer this

Use this endpoint when you need to apply the published Licurse 2010 clinical prediction rule exactly as validated — seven boolean flags mapped to a deterministic point score — to stratify AKI patients by hydronephrosis risk. Prefer it over manual calculation when embedding clinical decision support in automated workflows, EHR integrations, or clinical agent pipelines where reproducibility and auditability matter. Not appropriate for ordering imaging, diagnosing conditions, or assigning race — the caller must supply all clinical determinations.

## Known failure modes

- Missing any of the seven required boolean query parameters returns a validation error
- Incorrect data types (non-boolean values) cause a schema validation failure
- Network or server errors return HTTP 5xx with no score
- Score outside 0–10 would indicate a misconfiguration in caller-supplied inputs

## How this service works

Licurse 2010 AKI hydronephrosis points: history of hydronephrosis +4; nonblack (black=false) +1; recurrent UTI +1; obstruction-consistent diagnosis (mass, BPH, pelvic surgery, or neurogenic bladder) +1; absence of inpatient nephrotoxins, CHF, and prerenal AKI (pressor or sepsis) +1 each. Score 0-10. 2010 split only: <=2 low (HN 3.1%, HNRI 0.4%), >=3 higher (HN 15.7%, HNRI 4.7%). Not an imaging order. magent does not assign race or perform ultrasound.

## Output

Returns the total Licurse 2010 score (0–10), the risk stratum (low if ≤2, higher if ≥3), and the associated probability estimates for hydronephrosis (HN) and hydronephrosis requiring intervention (HNRI) based on the 2010 split thresholds (low: HN 3.1%, HNRI 0.4%; higher: HN 15.7%, HNRI 4.7%).
