A staghorn calculus is a very large and often irregularly shaped kidney stone that grows in one or both kidneys. Having certain kinds of urinary tract infections can increase the risk of developing them. They generally do not move because they are so large - usually they are discovered on an ultrasound, ct, or mri.
Background. Upper urinary tract stones that involve the renal pelvis and extend into at least 2 calyces are classified as staghorn calculi (see image below). Although all types of urinary stones can potentially form staghorn calculi, approximately 75% are composed of a struvite-carbonate-apatite matrix.ndications. Staghorn calculi represent a less-common nephrolithiasis subgroup so named because the significant stone burden that fills the renal pelvis and calyces forms a shape on radiographs that resembles a deer's horns.
