How this service works
Kutikov 2009 R.E.N.A.L. nephrometry. Caller-assigned radius le_4 1 / gt_4_lt_7 2 / ge_7 3 (cm); exophytic ge_50 1 / lt_50 2 / entirely_endophytic 3; nearness ge_7 1 / gt_4_lt_7 2 / le_4 3 (mm); location entirely_polar 1 / crosses_polar 2 / gt_50_midline_or_between 3. Anterior a|p|x and hilar suffix h are descriptors, not points. Sum 4-12. No published complexity bands. Not PADUA. Not STONE nephrolithometry. magent does not read CT. Not a medical device. Not a nephrectomy order.
Output
Returns the integer R.E.N.A.L. nephrometry sum (4–12), individual component scores for each dimension (R, E, N, A, L), the echoed anterior descriptor (a/p/x), and the hilar suffix flag. Does not provide complexity band classifications or surgical recommendations.
Example use cases
Pre-op complexity scoring for partial nephrectomy
“I have a kidney tumor that's 6 cm in maximal diameter, less than 50% exophytic, the deepest part is about 3 mm from the collecting system, it's posterior, entirely between the polar lines, and it doesn't touch the main vessels — can you give me the R.E.N.A.L. nephrometry score?”
Radiology report structured data enrichment
“A renal mass on the right kidney measures 8 cm (so ≥7 cm), is entirely endophytic, sits ≤4 mm from the sinus, is indeterminate anterior/posterior, crosses the axial renal midline, and abuts the main renal artery — compute the R.E.N.A.L. nephrometry score for the report.”
Research dataset nephrometry scoring
“For this study case: tumor radius ≤4 cm, ≥50% exophytic, ≥7 mm from the collecting system, anterior location, entirely above the upper polar line, no hilar involvement — what's the Kutikov nephrometry score?”

Endpoint
GEThttps://api.magentlab.com/api/calc/renal_nephrometryWhen to prefer
Choose this endpoint when you need a programmatic, structured computation of the Kutikov 2009 R.E.N.A.L. nephrometry score from already-interpreted imaging descriptors. It is ideal for automating radiology workflow enrichment, populating clinical research databases, or embedding nephrometry scoring into a urology decision-support agent. It is NOT a substitute for radiologist interpretation of CT images, does not implement PADUA or STONE scoring, and is not a medical device.
Side effects
- Missing required query parameters returns a validation error
- Invalid enum values for radius, exophytic, nearness, anterior, or location return a 400-level error
- Hilar parameter missing or non-boolean returns an error
- Network timeout or service unavailability returns a 5xx error
- Payment failure via x402 protocol prevents the call from completing
