 Answer the question below. Please respond with the option letter (A, B, or C) first. (HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.) 

Question:
Is fluoroscopy essential for retrieval of lower ureteric stones? 

Options:
{'A': 'yes', 'B': 'no', 'C': 'maybe'}'

[2025-09-25T11:26:04.966230] [PI reasoning] **Responding to article conclusions**

I see that the article I have includes the conclusion stating that ureteroscopic stone retrieval can be performed safely without fluoroscopy for many patients. The title suggests we consider whether fluoroscopy is essential. Based on the conclusion, the answer is “B” (no). I need to follow instructions and provide just the option letter “B” first, and then perhaps a brief justification after, even if it is optional. I'll make sure to keep it straightforward!
