What should you know about intravesical therapy?

Intravesical means inside the bladder. A healthcare professional passes a thin catheter through the urethra and puts the medicine into the bladder. You may be asked to keep it there for a specified period before urinating. Because the medicine is delivered locally, the treatment plan differs from medicines given through a vein.

The exact product depends on the cancer, its depth and grade, previous treatment, and your health. Intravesical chemotherapy and intravesical BCG are examples used in selected bladder cancers. The approach does not apply to every tumour or every stage of disease.

Before treatment, tell the clinic about urinary infection symptoms, blood in the urine, difficulty passing urine, recent procedures, allergies, and medicines. Follow instructions about drinking, holding the medicine, cleaning the toilet, and hand hygiene. The clinic will tell you when normal activities can resume.

Burning, urgency, and frequent urination may occur for a short time. Keep the treatment unit's contact details nearby and record symptoms, temperature, and fluid intake if asked. Planned cystoscopy or other reviews help the team decide what happens next.

Seek prompt medical advice for fever, shaking chills, severe pain, inability to pass urine, heavy blood in the urine, faintness, or marked weakness. These symptoms should be assessed rather than treated as routine bladder irritation.

Which medicine will I receive and why? How is it inserted? How long must it remain in the bladder? What preparation and toilet precautions are needed? Which symptoms are expected, and which require urgent help? How will the team check whether treatment is working?
