To critically analyse the relationship of bladder pain syndrome (BPS/IC), as defined, to the posterior fornix syndrome, "PFS" predictably co-occurring bladder urgency, frequency, nocturia, chronic pelvic pain, emptying symptoms/retention, caused by uterosacral ligament (USL) laxity and cured by USL repair. The starting and end points of this paper are the questions, "Are there arguments that BPS/IC can, in some cases, be linked to PFS?" And if so, "To what extent?" We used the criteria required by Ueda for proper diagnosis: "understanding symptoms, detecting abnormal findings and verifying them as a cause of the symptoms." Literature, diagnostic and surgical, indicate that chronic pelvic pain "of unknown origin" can be caused by unsupported visceral pelvic plexuses because of weak USLs; these cause fire of afferent impulses, which the brain mistakenly interprets as coming from the end-organ itself (i.e., genitourinary pain, lower urinary tract symptoms). The same lax USLs can also weaken the pelvic muscles which contract to stretch the vagina to support the urothelial stretch receptors from below: these may prematurely fire off afferent impulses to activate micturition at lower bladder volumes, interpreted as urgency. A speculum placed in the vagina can relieve pain and urgency by mechanically supporting the vaginal wall and USLs, thus predicting an eventual cure by USL repair. There is need to evaluate what percentage of women with known BPS/IC also pass the criteria for PFS. Identifying a significant percentage of BPS/IC women with the causative relation between PFS pathogenesis and BPS/ IC may open a new way of diagnosing and treating BPS/IC in some women.
