Renal calculi larger than 20mm in diameter represent a distinct, high-burden clinical scenario. Stones of this size require a specific first-line approach that differs from the management of smaller stones.
This protocol addresses patients with kidney stone disease where the stone measures more than 20mm (>2cm) in diameter. At this size, standard non-invasive options carry meaningful limitations, and guideline-directed care specifies a preferred procedural strategy.
For stones of this size, guidelines support a percutaneous renal procedure as the primary intervention. The full clinical protocol — including procedural details, decision pathway, and management algorithm — is available in the complete structured regimen.
