Don’t perform ultrasound on boys with cryptorchidism.

Ultrasound has been found to have poor diagnostic performance in the localization of testes that cannot be felt through physical examination. Studies have shown that the probability of locating testes was small when using ultrasound, and there was still a significant chance that testes were present even after a negative ultrasound result. Additionally, ultrasound results are complicated by the presence of surrounding tissue and bowel gas present in the abdomen.

How The List Was Created

1–5: The American Urological Association (AUA) established a committee to review evidence from the association’s guidelines and identify potential topics for nomination to the AUA’s Choosing Wisely list. The committee reviewed a number of recommendations and through a consensus process identified the five tests or procedures that should be questioned. These recommendations were reviewed and approved by the AUA Board of Directors.

6–10: Following its previous successful participation in Choosing Wisely in 2013, the American Urological Association (AUA) established a new committee in 2014 to develop a second list of recommendations. The group sought input from the AUA membership in addition to drafting potential suggestions after studying evidence from the association’s evidence-based clinical practice guidelines and other clinical documents. The committee reviewed all recommendations and narrowed them to a list of fifteen possibilities. Again, the committee sought AUA member input by asking members to vote for their top five selections from the list of candidate recommendations. After the votes were tallied, the list of five recommendations was determined. These recommendations were reviewed and approved by the AUA Board of Directors in February 2015.
