Cystoscopy is a minimally invasive procedure to investigate conditions that may present in the bladder. During a cystoscopy, a thin tube with a camera and light on the end is inserted through the urethra. Magnified images are displayed on a screen.

A cystoscopy can reveal several conditions, including bladder tumors, stones or cancer. Your doctor can also use this procedure to diagnose:

  • blockages
  • enlarged prostate gland
  • noncancerous growths
  • problems with the ureters (tubes) connecting your bladder to your kidneys

Cystoscopy can also be used to treat underlying bladder conditions. Your doctor can pass tiny surgical tools through the scope to remove small bladder tumors and stones or to take a sample of bladder tissue without an incision. Other uses include:

  • taking a urine sample to check for tumors or infection
  • inserting a small tube to assist with urine flow
  • injecting dye so kidney problems can be identified on an X-ray
