| Category | Reason |
|---|---|
| Metabolic | Most kidney stones arise from metabolic imbalances, including: – Hypercalciuria – Hyperoxaluria – Hyperuricemia – Cystinuria |
🔄 Secondary (Contributing) Categories Based on Etiology
| Category | When Applicable |
|---|---|
| Infectious | If due to struvite stones from urease-producing bacteria (e.g., Proteus) |
| Inherited | In cystinuria or primary hyperoxaluria (genetic conditions) |
| Mechanical | When secondary to urinary obstruction or stasis (e.g., UPJ obstruction) |
| Iatrogenic | Post-surgical or due to medications that promote stone formation |
| Idiopathic | If no identifiable metabolic or structural cause is found |
