Cardiopulmonary exercise testing prior to radical cystectomy: a systematic review and meta-analysis.

Objective: To identify the association between cardiopulmonary exercise testing (CPET) and outcomes of radical cystectomy (RC), as RC is historically associated with high rates of short- and long-term morbidity and mortality.

Methods: This quantitative systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. An electronic literature search was conducted to identify all relevant studies evaluating the relationship between CPET parameters and RC outcomes.
