What is the difference between ureteroscope vs cystoscope?

Answer 1

Ureteroscopy (URS): This treatment involves the use of a very small, fiber-optic instrument called a ureteroscope, which allows access to stones in the ureter or kidney. The ureteroscope allows your urologist to directly visualize the stone by progressing up the ureter via the bladder. No incisions are necessary and general anesthesia is used to keep the patient comfortable during the procedure.

Once the stone is seen through the ureteroscope, a small, basket-like device can be used to grasp smaller stones and remove them. If a stone is too large to remove in one piece, it can be fragmented into smaller pieces. Most commonly this is accomplished with laser energy.

Once the stone has been completely treated, the procedure is done. In many cases, the urologist may choose to place a stent within the ureter, to allow any post-operative swelling or reaction to subside.

A cystoscopy is an examination of the inside of the bladder and urethra, the tube that carries urine from the bladder to the outside of the body. In men, the urethra is the tube that runs through the penis. The doctor performing the examination uses a cystoscope-a long, thin instrument with an eyepiece on the external end and a tiny lens and a light on the end that is inserted into the bladder. The doctor inserts the cystoscope into the patient's urethra, and the small lens magnifies the inner lining of the urethra and bladder, allowing the doctor to see inside the hollow bladder. Many cystoscopes have extra channels within the sheath to insert other small instruments that can be used to treat or diagnose urinary problems.

Answer 2

A ureteroscope is a tool used to visualize and access the ureter and kidneys, while a cystoscope is used to examine the bladder and urethra. The ureteroscope is longer and thinner, allowing it to reach the upper urinary tract, while the cystoscope is shorter and wider to navigate the bladder. Both instruments are inserted through the urethra for diagnostic or therapeutic procedures.
