This review is based on a data search up to the end of January 2012 on strategies in the treatment of non-muscle-invasive bladder cancer. One of the authors was chairman of the guidelines writing committee of the European Association of Urology, and these guidelines served as a backbone. They are updated and adapted according to the most recent data. It is astonishing how much important data were published in the last 2 years. Many data have a high level of evidence and allow well-supported recommendations. However, recommendations are not given but the discussion for reflection on it is given in this article.
