I'm going to disagree with leaving it off the forum, changes in pH are noted as a side effect of vaping, and substantial change to pH is a contributing factor in encouraging growth of bacteria and emergence of cystitis (UTI).
As far as sources, I'd prefer something more like:
David S Howes, MD, Residency Program Director, Professor of Medicine, Section of Emergency Medicine, University of Chicago/Pritzker School of Medicine
For eMedicine/WebMD
As/Per:
Urinary Tract Infection, Female: eMedicine Emergency Medicine
Note Pathophysiology, PP2
This would allow us to speculate that observing substantial pH changes in vaping and acute UTI may not be unrelated. Not as the vector, of course, but as a potential contributing factor.
Now - specifically stated, where is the disagreement to this hypothesis?
As always: consult with a qualified medical doctor (or two or three) for medical conditions. Forum discussions are DISCUSSIONS, not diagnosis.
