In the only randomized trial of TURP vs open prostatectomy that has ever been reported, two of 32 patients died within 5 years of open prostatectomy, compared with nine of 43 patients following transurethral prostatectomy.2 This difference in proportions is statistically significant (P<.05) using a one-tailed t test. Recent studies have documented hemodynamic and cardiovascular changes during and subsequent to transurethral prostatectomy.3,4 Thus, the finding of increased mortality is no longer completely atheoretical.The comorbidity data used to adjust the relative risk (RR) of death following prostatectomy were collected uniformly and prospectively on 1650 men at the University of Manitoba, as reported in our first article.5 As these data
