Purpose
Vaginal/perineal pain is common following obstetric trauma or vaginal surgery for prolapse and may have a serious impact on sexual function and quality of life. Local injections of corticosteroids, local anaesthetic and hyaluronidase are treatment options for chronic pain; however, there are no published studies to support their efficacy. The objective of this study was to evaluate prospectively the efficacy of perineal/vaginal injections for chronic localised pain following childbirth or vaginal surgery.
Methods
Consecutive women with chronic vaginal/perineal pain were recruited in this prospective series (audit). Pain severity and sexual function were determined using a visual analogue scale (VAS 0–10) and the abbreviated sexual function questionnaire (ASFQ) respectively. Patients underwent local injections with a combination of 0.5% bupivacaine (10 ml), hydrocortisone (100 mg) and hyaluronidase (1,500 IU). Follow-up was undertaken at four-weekly intervals. Further injections were performed as clinically indicated.
Results
Fifty-three women underwent ≥1 injections [mean: 1.86 (range: 1–4)]. Mean interval from index childbirth [43/53 (81%)] or surgical intervention [10/53 (19%)] was 8 months (range 12 weeks–20 years). Twenty-seven women (51%) were sexually active. All reported dyspareunia. Fifteen (28%) women required 1 and 31(59%) two injections. Pre treatment VAS pain scores were 6.1 versus 4.1 after first injection (p = 0.0002, 95% CI 1.01–3.05) and mean ASFQ scores increased from 18.1 to 29.1 (p = 0.01, 95% CI −17.2 to −2.3) 4 weeks post-injection. There were no adverse events or morbidity. 24/27 (89%) sexually active women with dyspareunia resolved and 18/26 (69%) sexually inactive women resumed satisfactory sexual activity 8 weeks post-injection.
Conclusion
In our series, this treatment was well tolerated and significant improvements in pain scores and sexual function were observed.
