Re: Petros, P. An anatomical explanation for 'urodynamic features and artifacts'. Neurourol urodyn 2014; 33:153-4

摘要

Peter Petros is to be commended for trying to invent alternative interpretations for the changes in pressure during bladder filling and voiding identified by Hogan et al., and I agree with him that, in the pelvis, complicated anatomical changes occur, with mechanical effects that are difficult to foresee. However, someone challenging convention requires compelling evidence that something is wrong with the older view, and in this particular case the difficulty is that anatomical imaging, however carefully done, gives information only about changes in geometry and not about the forces causing them. So any inference based on forces is purely speculative: it requires further experimental evidence to make it at least plausible.
