Effect on postoperative survival of the status of distal ureteral margin: The necessity to achieve negative margins at the time of radical cystectomy.

2015

Background: Despite several studies, the adequate management of positive distal ureter margins at the time of radical cystectomy (RC) remains controversial. Particularly, it is not clear whether the achievement of negative distal ureter margins at the intraoperative frozen sections (IFS) affects postoperative cancer-specific mortality (CSM). Methods: In all, 1,447 consecutive patients treated with RC at a single center between January 1987 and August 2014 were considered. Multivariable (MVA) logistic regression analyses were used to determine predictors of positive IFS. MVA Cox regression analyses were used to test the effect on CSM of intraoperative conversion to negative margins. Results:…
