What shape is associated with Cystine stones?

Cystine stones are characteristically associated with a hexagonal shape. This unique formation is a result of the specific crystallization pattern of cystine, an amino acid that can crystallize in the urine of individuals with cystinuria. The hexagonal crystals are often noted in microscopic examinations of urine and are important for identifying and managing cystine stone disease. Identifying the shape of the stones helps in determining the underlying metabolic disorders and tailoring appropriate treatment strategies.

In contrast, other stone types have different shapes; for instance, calcium oxalate stones can often present as envelope or dumbbell shapes, while struvite stones may appear as staghorn configurations. Understanding these distinctions can aid in diagnosing the underlying conditions leading to stone formation.
