The cystoscopy instruments are kept ready after being sterilized. The nurse cleans the area around the urethral opening. A local anesthetic is kept ready and is given to the patient before the examination starts.
Patients who have to undergo cystoscopy should check with their doctor for any special instructions. People who have undergone cystoscopy can eat normally before the test while for ureteroscopy, the patient may not be permitted to eat before the test.
Any type of medical procedure involves a minor risk of injury; therefore patients have to sign a consent form before undergoing the test. The patient should feel free to ask the doctor if he has any doubts or concerns.
Before the test starts, the patient has to give a urine sample to check if there’s infection. The patient is not supposed to urinate at least an hour before the test. Mostly, the patient should lie on the back with apart and raised. After this, a nurse cleans around the urethral opening and injects a local anesthetic for the patient to be comfortable while the test is going on. Patients who have to undergo uretheriscopy are injected with general anesthetic.
After being given the local anesthea the patient loses sensation in the urethra, the doctor then carefully inserts the tip of the cystoscope in the urethra and then gently moves it up inside the bladder. Then a sterile liquid which consists of salt water known as saline flows from the scope, which fills the bladder and stretches. This is done so that the doctor can view the bladder wall properly.
When the bladder is filled with the liquid, the patient’s bladder is filled and he is not in a comfortable position, and urges to urinate. The doctor releases a little fluid or gives time to the patient to urinate as soon as the test is over.
It takes only a couple of minutes to insert the cystoscope and then remove it. There are chances that the process of Cystoscopy may take more time if the doctor finds a stone and suggests for a treatment. While taking a biopsy, a tiny sample of the tissue is taken for examination with the help of a microscope. This will extend the length of the procedure and in such cases the entire test along with the preparation takes 15-30 minutes.
