Question

What is correct regarding the image shown?

• A. Non-invasive and gold standard of cancer
• B. Non-invasive and can diagnose PUJ obstruction
• C. Percutaneous method
• D. Invasive and therapeutic for bladder lithiasis

Hint:

PUJ obstruction is commonly evaluated using non-invasive imaging that assesses urinary drainage.

Answer 1

The Correct Option is B

Concept: Imaging modalities such as renal scans or functional imaging can be used non-invasively to diagnose pelvi-ureteric junction obstruction. PUJ obstruction causes impaired drainage from the renal pelvis into the ureter.

Step 1: Identify the key diagnostic purpose.
The question asks about an image-based investigation related to urinary tract evaluation.

Step 2: Understand PUJ obstruction.
PUJ obstruction causes obstruction at the junction between renal pelvis and ureter. It can be diagnosed using non-invasive imaging.

Step 3: Select the correct statement.
Among the given options, the correct statement is: \[ \text{Non-invasive and can diagnose PUJ obstruction} \] Therefore, the correct answer is Non-invasive and can diagnose PUJ obstruction.
