Summary
Brief summary
The purpose of this study is to determine if continuous irrigation of the bladder using sterile water for at least 3 hours is feasible and safe in bladder tumour resection.

Who is it for?
You may be eligible for this study if you are an adult who is suspected of having bladder cancer.

Study details
Standard surgery for bladder tumours involves irrigation of the bladder during and after the surgery using sterile saline (salt water). If you participate in this study, you will have sterile water used for this irrigation during and for at least 3 hours after surgery instead.

If irrigation using water is found to be feasible and safe, it can then be assessed further to see if it can prevent the bladder cancer. from coming back. This could have a major impact on treating bladder cancer
