Low-risk patients (defined by D’Amico criteria and National Comprehensive Cancer Network guidelines) are unlikely to have metastatic disease. Accordingly, imaging is generally unnecessary in patients with newly diagnosed prostate cancer who have a PSA <20.0 ng/mL and a Gleason score 6 or less unless the patient’s history or clinical examination suggests distant disease. Metastases are much more likely in high-grade disease that is characterized by fast and aggressive growth into surrounding areas such as bones or lymph nodes.

Studies suggest that asymptomatic bacteriuria in the elderly does not carry significant risk of morbidity if left untreated. Antimicrobial treatment studies for asymptomatic bacteriuria in older adults demonstrate no benefits and show increased adverse antimicrobial effects. Consensus criteria has been developed to characterize the specific clinical symptoms that, when associated with bacteriuria, define urinary tract infection. Screening for and treatment of asymptomatic bacteriuria is recommended before urologic procedures for which mucosal bleeding is anticipated.

Ultrasound is of minimal value in localizing the position or existence of testes that cannot be felt through physical examination. Studies have shown that there remained a significant chance that testes were present even after a negative ultrasound result. The likelihood of locating testes is low when using ultrasound.

The Canadian Urological Association (CUA) utilized its guidelines committee to review evidence from the association’s guidelines and the suggestions put forward by the American Urological Association (AUA) to identify potential topics for nomination to the CUA’s Choosing Wisely Canada list. The general membership had the opportunity to put forward suggestions after being notified of the process via email. 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 CUA guidelines committee. Recommendations 1, 3 and 5 were adopted with permission from the Five Things Physicians and Patients Should Question, © 2013 American Urological Association. Recommendation 4 was adopted with permission from the Ten Things Physicians and Patients Should Question, © 2015 American Geriatrics Society, New York, New York.
