(460) A Case Series on Vulvovaginal Obliteration

Abstract

Abstract Introduction Between Dec. 2018 & June 2020, 5 cases of Vulvovaginal Obliteration, also known as Labial Adhesion were diagnosed, evaluated and treated. All of the presenting cases had a history which shared certain features, including more than 2 decades without sexual activity, no history of masturbation, no use of hormone replacement therapy and chronic urinary tract symptoms. The most severe case had the longest period without vaginal penetration (>30years). In 3 of the 5 cases the patients didn't have a partner, while the other 2 patients were not sexually active with their partner in any way. Objective To add new cases to the literature about this rarely described disorder. To show this condition is one of the most extreme consequences of Genitourinary Syndrome of Menopause. To demonstrate the importance of vaginal penetration and hormone replacement therapy (HRT) to prevent postmenopausal labial adhesion. Methods This is a case series reviewing the effective management of labial adhesion in post-menopausal women. Results In 2 of the cases the patients main complaint was their inability to urinate due to obstruction of the urethral outlet by the fused labia. This obstruction caused urocolpos, extremely distended urinary bladder, megaloureters, & bilateral hydronephrosis. Leakage of urine also occurred at the posterior fourchette. All of these urinary symptoms disappeared after an urgent introital incision was performed in the OR. In both cases the exclusive use of local estrogens postoperatively failed to prevent recurrent closure. Only the combined use of local estrogens and the regular use of dilators (3-4 times/day/2 weeks, then 1-2 times /day/2 weeks, then PRN) prevented recurrence. In 3 of the 5 cases, regular use of the dilators caused them to reach orgasm for the first time in their lives. The ages of these women were between 76 & 92 years old. The last 2, and more mild cases had 50% labial fusion, without urinary retention. The use of progressively increasing sizes of dilators and estrogen cream resolved the problem without surgical interventions. Conclusions Labial adhesion is one of the worst consequences of GSM, due to progression towards urinary retention. It is caused by insufficient maintenance of sexual activity after menopause, combined with lack of prevention with HRT, and is successfully managed with surgery, dilators and topical estrogens.
