Chapter 4 108 TPUS versus DRE by the surgeon (n=32) In 17 patients (52%) the tests showed similar results. Twenty-five (78%) patients were classified ‘indifferent’ with TPUS (Table 14).

DRE by the surgeon versus evacuation of gel during TPUS (n=24) One patient showed ‘paradoxical’ straining during DRE by the surgeon but could evacuate the gel during the TPUS at the same day (Table 15). One patient could not evacuate the gel while the surgeon classified ‘relaxation’ with DRE. Table 15.

S-EMG versus DRE by the surgeon (n=50) In 26 (52%) patients the test results were similar. S-EMG classified ‘indifferent’ in 22 (44%) patients (Table 16). One patient was classified ‘paradoxical’ with s-EMG but classified ‘relaxation’ by the surgeons’ DRE.
