OBJECTIVE: This study aimed to investigate the influence of endocervical pH on vaginal pH, and also the changes in these pH values following hysterectomy and cold-knife conization. Vaginal pH is important for maintaining the equilibrium of the vaginal microflora.
PATIENTS AND METHODS: Two groups of women were studied: the first (n = 20, median age 45, range 33-50 years-old), before and after hysterectomy (without ovariectomy) for myomatosis; the second group (n = 18, median age 38.5, range 37-65 years-old), before and after cold-knife conization for cervical intraepithelial neoplasia (CIN) grade II or III. Four samples (before and 90 days after surgery) were collected from the women by means of swabs: (1) anterior vaginal fornix, (2) posterior vaginal fornix, (3) posterior wall of lower vagina, and (4) endocervix (except in cases after hysterectomy). The pH was measured using a digital pHmeter (Sentron).
RESULTS: We observed that endocervical pH was less acidic than were all the vaginal locations measured, before both surgeries. After both surgeries, all vaginal pH measurements were higher, but without reaching statistical significance. Endocervical pH correlated with vaginal pH.
CONCLUSIONS: We concluded that recent hysterectomy does not alter vaginal pH and that vaginal and endocervical pH values are related.
