Background: Radiotherapy (RT) is a choice to manage pelvic organ malignancies that can affect bladder; therefore, it causes radiation cystitis with some bothering urinary symptoms and decreasing the patient’s quality of life. Intravesical hyaluronic acid (HA) is an agent with promising results in some studies for cystitis, and Cystistat is a derivative of hyaluronic acid. Objectives: This clinical trial aimed at evaluating the effects of intravesical instillation of Cystistat on symptoms of radiation cystitis and quality of life (QOL). Methods: A total of 58 patients with radiation cystitis were randomized in 2 groups (case: 30, control: 28). One group received intravesical Cystistat, the other received normal saline weekly for up to 4 weeks and then monthly for up to 2 months. Hematuria, Visual Analog scale (VAS) and QOL based on King’s Health questionnaire were compared before and 3, 6 and 9 months after intravesical instillation. Results: The mean age of the patients was 63.93 ± 10.89 years old. The mean of each sub-category of QOL and total score of QOL, as well as, VAS score were significantly improved in comparison to the control group at each time of follow-ups (P < 0.05). Hematuria was significantly different in the 3rd, 6th and 9th month of follow-ups (P < 0.05). Conclusions: Findings showed that patients with radiation cystitis could significantly benefit from intravesical instillation of HA, their hematuria would be successfully resolved rather than control group in addition to lowering the VAS score, so their QOL would be improved.
