The Olympus WA22810A is a 22.5 Fr cystoscope outer sheath designed for use in urological endoscopic diagnosis and treatment procedures. It serves as a protective and functional conduit through which a rigid cystoscope and other instruments are introduced into the urinary tract for inspection, biopsy, or intervention. The sheath is constructed for repeated sterilization and clinical durability. It is typically paired with an optical obturator (model WA22840A) for atraumatic, visualized insertion. The WA22810A sheath is compatible with 4 mm rigid cystoscopes and supports fluid irrigation during procedures.

This sheath is widely used in urology for cystoscopy and other lower urinary tract endoscopic procedures, providing a safe, durable, and functional access channel.
