What is the name of the examination of the bladder with a cystoscope?

Cystoscopy is the procedure that involves the examination of the bladder using a cystoscope, which is a specialized instrument that allows visualization of the bladder's interior. This procedure enables healthcare professionals to diagnose various bladder conditions, such as infections, tumors, or structural abnormalities. During cystoscopy, the cystoscope is inserted into the urethra and advanced into the bladder, providing a direct view for assessment or potential treatments, such as biopsy or removal of stones.

The other choices refer to different medical procedures or conditions. Dialysis is a treatment for kidney failure that removes waste products and excess fluid from the blood. Catheterization involves the insertion of a catheter into the bladder to drain urine or provide access for other procedures. Glomerulonephritis is a type of kidney disease characterized by inflammation of the glomeruli, which affects filtering in the kidneys but is unrelated to the examination process of the bladder. Therefore, the correct term specifically associated with the examination of the bladder using a cystoscope is cystoscopy.
