We use cystoscopy to examine the lining of your bladder and the tube that carries urine out of your body (the urethra). We insert a hollow tube (cystoscope) equipped with a lens into your urethra and slowly advance the tube into your bladder. We can do this procedure in a testing room, using a local anesthetic jelly to numb the urethra. We might also perform cystoscopy as an outpatient procedure, with sedation. Another option is to have cystoscopy performed in the hospital under general anesthesia. Where you go depends on the reason for your procedure. We might recommend cystoscopy to:

  • Investigate causes of symptoms including blood in the urine, incontinence, overactive bladder, and painful urination. Cystoscopy can also help our doctors determine the cause of frequent urinary tract infections (UTIs). However, we generally do not perform cystoscopy while you have an active UTI.
  • Diagnose bladder conditions such as bladder cancer, bladder stones, and bladder inflammation (cystitis).
  • Treat bladder diseases using special tools that can be passed through the cystoscope to treat certain conditions such as very small bladder tumors, which we might remove during cystoscopy.
  • Diagnose an enlarged prostate by revealing a narrowing of the urethra where it passes through the prostate gland, indicating an enlarged prostate (a condition known as benign prostatic hypertrophy or BPH).

What our patients say

Procedure went well. Staff was very friendly and concerned with any pain levels and care going forward. Doctor was very professional and described everything in detail before it happened.


Entire staff friendly and professional. Dr. Modder was patient and explained every step of the procedure. Results were explained. All my questions were answered. I felt comfortable that I was putting my health in good hands.


Going to a urologist can be a frightening experience. Dr. Vlach has always answered my questions with understandable responses. I left the visit with a sense of relief but also a dreaded appointment for next year. I trust Dr. Vlach. The staff are always professional but also very pleasant.
