The present invention includes strainers used to gather solids from voided urine. Embodiments include urinary bowl strainers, hand-held strainers and disposable hand-held urine strainers, all of which are particularly useful for gathering kidney stones passed in urine that are intended for verification of passing said kidney stones, and for laboratory analysis which may be used to guide clinical treatment to prevent recurrent kidney stone formation. Embodiments of disposable urine samplers are also disclosed. The embodiments of urine strainers and samplers disclosed herein are particularly adapted for use by female patients, though male patients may also use the devices.
