Baseline EF was graded on a validated five-point patient reported scale. NSS was graded intraoperatively by the surgeon, using a four-point NS score assigned to each nerve where 1\u2009=\u2009fully preserved, 2\u2009=\u2009partially preserved, 3\u2009=\u2009minimally preserved, and 4\u2009=\u2009resected. NS surgery was defined as NSS of 1 or 2 on both sides, and nerve resection surgery was defined as NSS of 3 or greater on both sides.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>On univariate analysis, factors related to nerve resection surgery included (all P\u2009&amp;lt;\u20090.01): increasing age (r\u2009=\u20090.16), Gleason score (r\u2009=\u20090.19), EF score (r\u2009=\u20090.21), percentage biopsy cores positive (r\u2009=\u20090.11), higher preoperative PSA (relative risk [RR] 1.72, 95% confidence interval [CI] 1.23\u20132.40), and clinical stage \u2265T2 (RR 2.17, 95% CI 1.68\u20132.78). On multivariable analysis, factors independently predicting for non-NS surgery included (all P\u2009&amp;lt;\u20090.01): baseline EF (odds ratio [OR] 1.50, 95% CI 1.33\u20131.68), biopsy Gleason sum (OR 1.95, 95% CI 1.65\u20132.36), clinical T stage \u2265T2 (OR 1.59, 95% CI 1.15\u20132.20), patient age (OR 1.07, 95% CI 1.04\u20131.09), and percentage of biopsy cores positive (OR 1.01, 95% CI 1.00\u20131.02).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>While unfavorable clinical and prostate biopsy characteristics predict less NS, we have shown that poorer baseline EF also independently predicts for nerve resection RP. For every point increase in EF score (that is, worsening EF) the odds of not receiving NS during surgery increase by a factor of 1.5. Although NS is not associated with worse cancer outcomes in appropriately selected patients, failure to spare nerves is associated with poor post-operative EF, urinary continence, and increased severity of cavernous venous leak. Patient anxiety related to cancer diagnosis and impending treatment may lead to falsely-worsened apparent EF when recent erections are assessed during a pre-operative planning visit. For these reasons prostatectomists should consider NS based solely on factors other than patient's baseline EF, even when it is impaired.<\/jats:p>\n
