What is the diagnostic procedure used for internal visualization of the urinary bladder?

The diagnostic procedure used for internal visualization of the urinary bladder is cystoscopy. This involves the insertion of a thin tube with a camera called a cystoscope through the urethra into the bladder. Cystoscopy allows healthcare providers to examine the bladder lining and urethra for abnormalities such as tumors, stones, or signs of inflammation. It can also be utilized for biopsy or to perform certain treatments directly.

Colonography focuses on the visualization of the colon rather than the urinary bladder, while endoscopy is a broader term that encompasses various techniques to visualize internal organs, but it typically refers to those involving the gastrointestinal tract. Laparoscopy is a surgical procedure used to view organs in the abdominal cavity, not specifically the urinary bladder. Hence, cystoscopy is the appropriate choice for this procedure.
