Instructions: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Input: Question: Is magnetic resonance arteriography/venography accurate to structure management of the impalpable testis?
Answer: Preoperative magnetic resonance imaging or magnetic resonance arteriography/venography does not accurately identify or localize impalpable testes in the age group typically presenting to pediatric urologists. Accuracy at our institution is discrepant with that in previous studies. We do not recommend using magnetic resonance imaging or magnetic resonance arteriography/venography for the possible observation of vanishing testes or nubbins and we recommend surgical exploration in all individuals.
Output:
no
