Clinical comparison of intravesical hyaluronic acid and chondroitin sulfate therapies in the treatment of bladder pain syndrome/interstitial cystitis.

Data comparing clinical efficiencies of different GAG therapies are very limited. In this study, intravesical CS was found superior to intravesical HA in terms of 24 h frequency, nocturia and ICPI in patients with BPS/IC in short term follow-up. To provide a definitive conclusion on superiority of one GAG therapy to others, further evaluation with long term follow up is required.
