Urinary diversion: evidence-based outcomes assessment and integration into patient decision-making.

There continues to be keen interest in assessing quality of life (QoL) after cystectomy and urinary diversion, given the recent evidence-based analyses [1,2] and systematic reviews [3–6] evaluating QoL studies in this population. A resounding characteristic of contemporary reports is the preponderance of cross-sectional, retrospective, single-institution studies. Very few prospective longitudinal studies and no randomized controlled trials have been reported, greatly limiting the ability to draw conclusions from reported observations. Despite this limitation, most of these studies show similarly favourable overall QoL after cystectomy, irrespective of the chosen urinary diversion.
