I read this publication with interest, but caution that the conclusions may not be robust due to methodological flaws which are common across many radical prostatectomy (RP) papers investigating the utility of prostate specific antigen density (PSAD), most of which fail to include an internal reference for correlation of the prostate volume estimate. Highlighting this flaw may serve as a template for future PSAD studies that involve RP specimens.
