Cystoscopes & Cysto Sheaths | 17Fr to 25Fr | DDP Elite Skip to content

Cystoscopes

A rigid cystoscope is a system, not a single instrument: a telescope, a sheath with an obturator, and a bridge that joins them and carries the working channels. This collection lists all of those parts for Olympus and Storz systems, along with complete laser cysto sets and flexible cystoscopes.

More than 130 items are listed, with French size, viewing angle and system named on each. Order a single sheath or bridge to complete an existing set, or ask us to quote a whole system.

Why Sheath Size Matters

The sheath sets the outer diameter of the whole instrument, and with it patient comfort and what can pass through the channel. A 17Fr sheath is gentler for diagnostic cystoscopy. A 21–25Fr sheath leaves room for working instruments, stone baskets and irrigation flow. Female oblique-tip sheaths are shorter and angled for the female urethra.

Storz-style sheaths are color-coded by size so the right one can be picked at a glance on the back table.

How to Choose

Telescope angle. 30º is the standard for bladder inspection; 70º and 120º look back toward the bladder neck and anterior wall.

Telescope diameter. Most sheaths here take a 4mm telescope. Check the listing when pairing a scope with a sheath.

Bridge. An examination bridge for diagnosis, single or double channel for passing instruments, deflecting for steering catheters into the ureters.

System. Olympus and Storz parts are not interchangeable. Storz-style parts list the matching Storz reference number.

Frequently Asked Questions

What do the sheath colors mean?
On Storz-style sheaths the color marks the French size: yellow 17Fr, green 19Fr, red 21Fr, blue 23Fr, white 25Fr.

Can I buy a sheath without an obturator?
Yes. Sheaths are listed both alone and with their obturator.

What is a retrospective cystoscope?
A telescope with a very wide angle (120º) that looks back toward the entry point, used to inspect the bladder neck.
