Patients and methods: We retrospectively reviewed the clinical records of patients with grade 2 BCG-induced chemical cystitis unresponsive to first line therapeutic options performed according to the International Bladder Cancer Group guidelines who underwent intravesical instillations of HA/CS. Bladder pain, urinary urgency, voiding volume and number of voids/24 hours recorded prior to treatment, at the end of the treatment, at six months and at one-year follow-up were recorded and analyzed. Results: The records of 20 patients were identified. All patients underwent eight weekly instillations of HA/CS. Mean baseline visual analogue scale (VAS) scores ¡À Standard Deviation (SD) for urinary urgency and bladder pain were 7.8 ¡À 0.5 and 7.2 ¡À 1.0, respectively. Mean number of voids/24 hours ¡À SD was 15.4 ¡À 2.3 and mean urine volume per void ¡À SD was 85.8 ¡À 21.0 mL. At the end of the treatment, mean VAS scores ¡À SD for urgency and pain significantly decreased to 4.7 ¡À 1.1 and 4.2 ¡À 0.9, respectively (p < 0.05 in both cases). Mean number of voids/24 hours ¡À SD decreased to 9.6 ¡À 1.4 (p < 0.05) and mean urine volume per void ¡À SD significantly increased to 194.1 ¡À 59.5 mL (p < 0.05). At six months and one-year followup, all outcome measures remained stable.
