The StoneScreen Kidney Stone Collection Cup was constructed to capture renal calculi and for use with patients attempting to pass stones following extracorporeal shock wave lithotripsy. The urine-straining device is a collapsible plastic strainer cup designed for both men and women and includes a nylon screen at the bottom of the cup for stone capture. Once the stone is captured, it can be placed in the storage space under the lid and saved for analysis.

By analyzing the stone’s physical and chemical make-up, a physician can prescribe medication or recommend a special diet to avoid recurrence of kidney stones in the patient. Examination of the stone can also confirm that the entire stone has passed and no longer blocks the ureters and urethra, reducing patient risk of infection.
