Cystoscopy

Cystoscopy is a diagnostic examination performed under local anesthesia or sedation, where a thin telescope is passed by the urologist through the urethra into the bladder. The bladder and the urethra, and in males, the prostate, can be seen and examined. Biopsies or treatments may be done through the cystoscope. Sometimes a tube or stent is passed to the kidney to help treat kidney stones or to take x-rays of the inside of the kidney.
