Custom Additional Information

In the United States, the incidence of urinary tract calculi is common, with one person in 1000 requiring hospital care and treatment. A typical urinary calculus is composed of crystalline substances precipitated in the body. To ensure proper treatment and prevention of recurrences of urinary calculi, it is critical that the crystalline constituents of the stone be identified. Mandel describes 15 crystalline substances common in urinary calculi and subdivides them into six broad catagories.1,2

Collection Instructions

Provide source (urinary, gall, salivary) of calculi. Avoid rejection and delayed processing by sending the stone completely dried in a clean container. Do not send gauze, filters, tape or Q-tips. Stones that are not received completely dried will result in delayed processing.

Storage Instructions

Maintain specimen at room temperature.

Causes for Rejection

Urine; stone analysis not performed on urine samples
