Definition : Devices designed to collect stones (i.e., calculi) from the urine during normal micturation. These strainers usually consist of a sieve with handles (e.g., built-in ridges) for easy manipulation; they are frequently attached to specimen containers. Each sample is sent to the clinical laboratory after stone collection for a pre-determined time period (usually 24 hours). Urine strainers are used every time the patient urinates during several days or weeks, typically until there are no stone fragments in the urine for several days. Determination of the chemical composition (e.g., calcium, cystine, uric acid) of calculi facilitates diagnosis and/or therapeutic treatment of the patient.
