What can cause a blurry image on a cystoscope?

• A. Dirty lenses
• B. Cacked glass rods
• C. Damaged lenses
• D. Light malfunction

Answer: (C)

A blurry image seen through a cystoscope can be attributed to damaged lenses. Lenses that have scratches, cracks, or other physical impairments can distort the light passing through, leading to unclear or hazy imagery. Proper visualization is crucial in procedures utilizing a cystoscope, as clarity is necessary for accurate diagnosis and intervention.

While dirty lenses, caked glass rods, and light malfunction can also cause image quality issues, the specific choice of damaged lenses directly relates to the integrity of the optical components designed to produce a clear view. When lenses are compromised, the entire function of the cystoscope can be adversely affected, leading to significant difficulties during a procedure. Thus, understanding the role of lens integrity aids in ensuring optimal performance of cystoscopic instruments.
