Purpose. To determine whether total psoas area (TPA), a simple estimate of muscle mass, is associated with complications after\nradical cystectomy. Materials and Methods. Patients who underwent radical cystectomy at our institution from 2011 to 2012 were\nretrospectively identified. Total psoas area was measured on preoperative CT scans and normalized for patient height.Multivariable\nlogistic regression was used to determine whether TPA was a predictor of 90-day postoperative complications. Overall survival\nwas compared between TPA quartiles. Results. 135 patients were identified for analysis. Median follow-up was 24 months (IQR:\n6ââ?¬â??37 months). Overall 90-day complication rate was 56% (75/135). TPA was significantly lower for patients who experienced\nany complication (7.8 cm2/m2 versus 8.8 cm2/m2,
