The significance of this test is largely historical. Chain-bead cystography involves the passage of a radiopaque chain transurethrally, with a portion of the chain piled just within the bladder at the urethrovesical junction. Urethra and bladder neck mobility, the presence or absence of urethral funneling, and the posterior urethrovesical angle can be determined with this test.

Incontinence experts no longer use this test. Instead, less invasive techniques, including the cotton swab test, bladder neck ultrasound, video urodynamics, and dynamic pelvic floor magnetic resonance imaging (MRI), now are used to study bladder neck anatomy and function.
