What is a common indication for performing a cystoscopy?

A cystoscopy is primarily used to visualize the interior of the bladder and the urethra, making it particularly valuable for examining bladder abnormalities. This procedure allows the healthcare provider to identify issues such as tumors, bleeding, or inflammation within the bladder lining, which can be crucial for diagnosing conditions like bladder cancer or interstitial cystitis. During a cystoscopy, the doctor can directly observe any irregularities and, if necessary, perform biopsies or other interventions.

In comparison, while evaluating kidney stones is a significant aspect of urological diagnostics, it is often addressed through imaging studies like ultrasounds or CT scans rather than through direct visualization of the bladder. A prostate exam is typically performed through digital rectal exams or ultrasound rather than a cystoscopy, as the latter focuses on the bladder and urethra. Lastly, analyzing urine composition involves laboratory testing of urine samples and does not require cystoscopic procedures, which are mainly visual examinations.
