    Abstract:
    INTRODUCTION AND HYPOTHESIS: Intravesical instillations of hyaluronic acid (HA) and chondroitin sulfate (CS) may lead to regeneration of the damaged glycosaminoglycan layer in interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS: Twenty-two patients with IC/BPS received intravesical instillations (40 ml) of sodium HA 1.6% and CS 2.0% in 0.9% saline solution (IALURIL, IBSA) once weekly for 8 weeks, then once every 2 weeks for the next 6 months. RESULTS: The score for urgency was reduced from 6.5 to 3.6 (p = 0.0001), with a reduction in pain scores from an average of 5.6 to 3.2 (p = 0.0001). The average urine volume increased from 129.7 to 162 ml (p < 0.0001), with a reduction in the number of voids in 24 h, from 14 to 11.6 (p < 0.0001). The IC Symptom and Problem Index decreased from 25.7 to 20.3 (p < 0.0001), and the Pain Urgency Frequency score, from 18.7 to 12.8 (p < 0.0001). CONCLUSION: The treatment appeared to be effective and well tolerated in IC/BPS in this initial experience.
