 Methodology and Project Plan. Participants Participants will be recruited from Health Board databases of those who have had advanced bladder cancer grade pT1 and above and undergone either IC or NB procedures within the last five years. Around 40 patients per year are referred to the ABMU; this is in line with expectations, given the size of the ABMU patient population 600,000 and rates of bladder cancer, giving a potential sample of 200 patients over the previous five years. This will provide an adequate population from which to sample participants. No form of payment will be offered for participation, but participants will be reimbursed for travel expenses. There will be no other inclusion or exclusion criteria in order to access a wide range of patients with potentially different values and lifestyles, and to aid in the recruitment of adequate sample sizes.
