Conclusions: CD produced a significantly higher potency rate at 1 month following LRP but similar rates thereafter, which are in step with previously reported values (Rozet, 2004). Notably, CD failed to reproduce the results of Menon et al. despite the advantage of avoiding cautery at all stages during NVB preservation in our patients. We believe that the merit of this technique is in allowing a clearer appreciation of the contour of the prostate base at the commencement of antegrade NVB dissection, rather than preserving important nerve fibres. This may explain the lower basal positive margin rate in the CD group of 0% vs 5.8% in control cases (p=0.007).
