Can a urologist find any abnormalities with my bladder while doing a cytoscospy?

Certainly can.: The cystoscope is nothing more than a camera and a very bright light (and some ports for injecting and sucking out fluids and for taking biopsies) on a stick. The urologist can see all manner of bladder things normal and otherwise once the camera is through the urethra.

Yes: Cystoscopy is a procedure in which a scope is placed inside the bladder to look for any abnormalities. It is possible to see stones, masses, ulcers, evidence of infection, hints of interstitial cystitis, and the relative size of the bladder. It is also possible to see if the ureters are functioning.

Not always: While cystoscopy is an invaluable tool for identifying bladder cancer and infection/inflammation as well as some congenital anatomic abnormalities, there are many neurological and functional abnormalities that aren't apparent on cystoscopic exam. Urodynamics and other testing is sometimes needed.
