 In their study, a total of 5798 TRUS-guided biopsies performed between 2002 and 2011. Increased incidence of infectious complications is noted from 0.52 infections per 100 biopsies between 2002 and 2009 to 2.15 infections per 100 biopsies between 2010 and 2011 P 0.001. The commonest organism found to be responsible for these infectious complications is Escherichia coli E. Coli.
