The feasibility of outpatient TPM has been well demonstrated.(Bianco \& Martínez-Salamanca, 2016; Merrick et al., 2016; Smith et al., 2014) New technology now allows for fusion of MRI images with TPM devices, allowing for targeting of cancerous-appearing lesions on MRI. Such technology that fuses MRI-imaging with TRUS biopsy has become routine in U.S. clinical practice, with improved cancer detection rates as compared with standard TRUS.(Ahmed et al., 2017; Robertson, Emberton, \& Moore, 2013)
This randomized trial will compare the safety and efficacy of TPM versus TRUS biopsies performed in the outpatient setting. Men will be randomized to receiving either TPM or TRUS targeted biopsy. All men will receive a urine culture within 2 weeks of biopsy and will be started on antibiotic prophylaxis prior to biopsy in accordance with AUA antimicrobial prophylaxis guidelines. Men with a positive urine culture will be treated with culture-specific antibiotics and must have a documented negative urine culture prior to biopsy.
