Evaluation of pain and quality of life after hyaluronic acid instillation in addition to botulinum toxin-A injection in women with refractory Interstitial Cystitis/Painful Bladder Syndrome: A pilot study

Objectives: The aim of this study was to assess changes in quality of life and pain alleviation in women with refractory Interstitial Cystitis/Painful Bladder syndrome following a combined intravesical injection of Botulinum Toxin-A and Hyaluronic Acid instillation versus Hyaluronic acid instillation alone. Methods: Two groups of women with painful bladder syndrome/interstitial cystitis were randomly divided (one to one randomization). Intravesical injections of botulinum toxin-A and intravesical Hyaluronic acid were given to Group (I). Only Hyaluronic acid was instilled intravesically in Group II. Patients were given voiding diaries, a visual analogue scale for pelvic pain, the International Cystitis Symptom Index and Problem Index, the Pelvic Pain Urgency/Frequency Patient Symptom Scale, and the Patient Health Questionnaire-9 to assess the candidates' quality of life. The Student t-test and mean and standard deviation were used in statistical analysis, with p 0.05 considered as significant (IBM SPSS statistics) Results: Thirty-four women were included in this study. The pain severity (VAS) of group (I) cases dropped dramatically from 8.5 ± 1.5 at the start to 3.9 ± 2.4 after three months and 2.9 ± 2.1 after six months. Among group (II) cases, the pain score reduced dramatically from 8.6 ± 1.3 to 5.8 ± 1.4 to 4.3 ± 2.6. Conclusions: In patients with refractory Interstitial Cystitis/Bladder Discomfort Syndrome, Botulinum Toxin-A injection combined with Hyaluronic Acid instillation improves pelvic pain and improves quality of life.
