Abstract

Objectives: To determine the effectiveness and safety of intravesical hyaluronic acid (HA) in symptomatic women with trigonitis and to correlate the severity of symptoms with the endoscopic and histological findings.

Methods: Thirty-seven patients (aged 20-46 years) were enrolled. All patients had cystoscopy and biopsy of the bladder trigone followed by intravesical instillations of sodium HA once weekly for 10 weeks and then once monthly for the next 10 months. Clinical response was evaluated by Pain and Urgency/Frequency (PUF) Symptom Scale, visual analog scale (VAS) for pain and urgency and functional bladder capacity. A repeat cystoscopy and biopsy were performed at the end of the treatment. Symptoms and cystoscopy and pathological findings were compared before and after treatment.

Results: The average initial score for pain was reduced from 5.5 to 2.8 (P < 0.001) at 10 weeks and further to 2.4 (P < 0.001) at 12 months and the score for urgency from 6.9 to 3.8 (P < 0.001) and further to 3.3 (P < 0.001). The average PUF score initially decreased from 20.5 to 12.1 (P < 0.001) and then further to 10.1 (P = 0.21). The mean functional bladder capacity increased from 125 to 204 mL (P < 0.001). No association was found between baseline PUF score and cystoscopy findings (P = 0.87). The PUF score was not changed significantly between patients with improved cystoscopy and those with stable findings (P = 0.74). No significant changes were reported between initial and final biopsies.

Conclusions: Intravesical HA appeared to be effective and well tolerated, although a clear relationship between symptoms and trigonitis was not confirmed.
