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

The image shows a nephrostomy tube, which is typically inserted using a cysto-urethroscope. This instrument is used for endoscopic visualization of the bladder and urethra, and it is commonly employed to place a nephrostomy tube into the renal pelvis in cases of obstructed kidneys. The tube is used for drainage when there is obstruction in the urinary tract, such as from kidney stones or tumors.
- Nephroscope is used specifically for visualizing the kidneys, but a cysto-urethroscope is preferred for placing tubes into the renal pelvis, particularly for nephrostomy.
- Ureteroscope is used for visualizing the ureter, but it is not typically used for placing a nephrostomy tube.
- Endoscope is a general term that can refer to any flexible tube used for internal examination, but the correct term for placing a nephrostomy tube is cysto-urethroscope.
Thus, cysto-urethroscope is the instrument used to insert a nephrostomy tube.
