Overview

With this prospective, observational study, we would like to investigate the effect of instillation therapy using BCG or mitomycin C on short- and long-term irritative and obstructive lower urinary tract symptoms using validated questionnaires. The study will objectify the lower urinary tract symptoms and thereby provide better recommendations for therapy with mitomycin C or BCG.

Eligibility

Inclusion Criteria:

• Urinary bladder carcinoma requiring instillation therapy
• Complete resection of the tumor
• No intravesical chemotherapy in the last 3 months

Exclusion Criteria:

• Patients who are unable to complete the questionnaires
• Patients who are not willing to participate
• Patients with contraindications for instillation therapy (allergic reactions, immunosuppression)
