Abstract

Aim of the study Hyaluronic acid chondroitin sulfate represents the replacement of the protective lining in bladder known as Glycosaminoglycan, or GAG layer. The aim of our prospective observational study is to evaluate the efficacy of hyaluronic acid chondroitin sulfate (Ialuril®) administration in men with bladder pain syndrome (BPS) after radiotherapy (RT) for prostate cancer. Materials and methods Twenty-three consecutive patients (mean age: 67.9) with bladder pain syndrome due to pelvic irradiation for locally advanced prostate cancer (16 treated with radical prostatectomy [RP] plus RT and 7 with RT alone) were enrolled from May 2012 to October 2013. Patients underwent intravesical administration of Ialuril® weekly for the first month, and on the 6th, 8th and 12th week subsequently. The Interstitial Cystitis Symptoms Index (ICSI), the Interstitial Cystitis Problem Index (ICPI) and Pelvic Pain and Urgency/ Frequency questionnaire (PUF) were self-administered immediately after RT and at the end of treatment with Ialuril (12th week) to evaluate the relapse of symptoms.
