Objectives: In this study, we aimed to find the answer to the question of whether intracavitary therapy administered for bladder tumor has any effect on the development of urethral strictures. Methods: The patients who underwent transurethral resection of the bladder with the diagnosis of bladder tumor in our clinic were divided into two as the group with urethral strictures and the group without urethral strictures. Intracavitary therapies, follow-up, and recurrence data of the patients of both groups were recorded. Results: The mean age of the patients with and without urethral stricture was 67.8 and 68.4 years, respectively. There was no significant difference between the T staging and grading of patients in the two groups. There was no statistically significant difference between the patients with and without urethral stricture in terms of intracavital therapy rates (p=0.943). Conclusion: Although we demonstrated that intracavitary therapy administered for bladder tumors had no effect on the development of urethral strictures, we believe we need randomized controlled trials with larger patient series.
