Abstract
OBJECTIVE: Painful bladder syndrome/interstitial cystitis (PBS/IC) and recurrent urinary tract infections (UTI) are clinically challenging conditions to manage in patients. We evaluate the clinical use of intravesical sodium hyaluronate (Cystistat®) in both these patient groups who have completed treatment. PATIENTS AND METHODS: Thirteen patients with recurrent UTIs (Group I) and 8 patients with PBS/IC (Group II) received intravesical sodium hyaluronate (Cystistat®). Preinstallation demographic parameters were statically comparable in both groups. The mean age of presentation was 54.6 years in Group I and 57.5 years in Group II (p = 0.9). All 13 patients in Group I were on low dose antibiotics. The mean number of installations completed in both groups was 9 (range 4-21). RESULTS: Data was collected prospectively using a standard pre- and post-treatment questioner with the pelvic pain and urinary/frequency patient symptom scale. At a mean follow-up of 21 months a significant improvement in bladder pain (p = 0.05), daytime frequency (p = 0.03) and quality of life (p = 0.02) was noted in patients in Group I. Two patients had breakthrough UTIs during treatment. Within Group I, 7 (53%) patients responded well to treatment. Patients in Group II had a significant improvement in bladder pain (p = 0.02), urgency (p = 0.01), nocturia (p = 0.01) and quality of life (p = 0.04). Within Group II, 6 patients (75%) responded to treatment. CONCLUSION: Intravesical sodium hyaluronate (Cystistat®) can be used with minimal side effects and good compliance in both groups of patients with PBS and recurrent UTIs. Longer follow-up and larger patient numbers in both groups will be required to confirm the long-term efficacy of these two clinically challenging groups of patients.
