cystoscopy

Full Definition

A minimally invasive diagnostic procedure where a thin, flexible or rigid telescope (cystoscope) is inserted through the urethra to visualize the bladder interior. This procedure allows direct inspection of the bladder wall, identification of abnormalities such as tumors, stones, or inflammation, and enables tissue biopsy collection. Cystoscopy is essential for bladder cancer surveillance and can be performed in office settings or operating rooms.
