Other diagnostic studies for urethral cancer include biopsy and ureteroscopy.

• Biopsy

• The removal of cell or tissue samples from the urethra, bladder, and, prostate gland.
• The samples are viewed under a microscope by a pathologist to check for signs of cancer.^[1]

• Ureteroscopy

• A procedure to look inside the ureter and renal pelvis to check for abnormal areas. A ureteroscope is a thin, tube-like instrument with a light and a lens for viewing. The ureteroscope is inserted through the urethra into the bladder, ureter, and renal pelvis. A tool may be inserted through the ureteroscope to take tissue samples to be checked under a microscope for signs of disease.
