Question

What instrument is used to insert this tube? 

• A. Nephroscope
• B. Cysto-urethroscope
• C. Ureteroscope
• D. Endoscope

Hint:

For placing a nephrostomy tube, a cysto-urethroscope is the appropriate instrument as it allows visualization of the bladder, ureters, and renal pelvis.

Answer 1

The Correct Option is B

To determine which instrument is used to insert the tube illustrated in the image, we need to understand the purpose and the anatomy involved. The choices provided are nephroscope, cysto-urethroscope, ureteroscope, and endoscope. Let's analyze:

• Nephroscope: Used primarily for direct visualization and treatment of the renal pelvis and calyces within the kidney.
• Cysto-urethroscope: Specifically designed for examining the urethra and the interior of the bladder. This tool allows surgeons to insert catheters or tubes into the bladder via the urethra.
• Ureteroscope: Utilized for accessing and treating conditions in the ureters, the tubes connecting the kidneys and bladder.
• Endoscope: A general term for instruments that allow internal examination of organs.
  

Considering the options, the Cysto-urethroscope is the instrument used for inserting tubes, such as catheters, into the bladder through the urethra, matching the described scenario. Therefore, the correct answer is:

Cysto-urethroscope
