First Use of Thermal Stabilized Hyaluronic Acid Injection in One-Year Follow-Up Patients with Genitourinary Syndrome.

OBJECTIVE

Evaluation of the impact of hyaluronan hybrid cooperative complex (HCC) injections in premenopausal and postmenopausal Italian women affected by vulvar-vaginal atrophy (VVA), one of the symptoms of genitourinary syndrome (GS), on self-reported quality-of-life, vaginal symptoms, and sexual activity, as well as treatment side-effects.

METHODS

We surveyed a sample of 26 women affected by VVA with follow-up at 6 and 12 months. Deep intradermal injections of HCC were delivered at 1-month intervals. Evaluation of the treatment impacting the VVA patients was assessed by three international validated questionnaires (Visual Analogic Scale, VAS; health-related quality-of-life test, SF12; Female Sexual Function Index, FSFI). The statistically significant differences between pre- and after-treatment responses have been assessed by Wilcoxon signed-rank test and repeated measures ANOVA test.

RESULTS

At 6-12-month follow-up, general quality-of-life (SF12) did not show any significant improvement. On the contrary, VVA patients showed significant improvements of genital symptoms (VAS) and sexual function (FSFI). Global FSFI score increased by 58% and evidenced important satisfaction (≤0.05).

CONCLUSION

Vestibular HCC injection is an office, safe, fast, not expensive, and reproducible procedure effective in vulvar-vaginal atrophy. This study can be used as a pilot for future trials.
