Abstract

Purpose: Transrectal ultrasound can be used to calculate prostate volume, which has implications for benign and malignant prostate disease. We hypothesized that obesity may represent a technical challenge when performing transrectal ultrasound that decreases the accuracy of estimating prostate volume. Materials and Methods: We examined the records of men with previously untreated prostate cancer who underwent radical prostatectomy between 1995 and 2006 and who were in the Shared-Equal Access Regional Cancer Hospital database. Transrectal ultrasound volume calculations were correlated with radical prostatectomy specimen weight using the Spearman coefficient. We calculated the percent and absolute error, and evaluated the relationship between them and transrectal ultrasound volume, body mass index, age, prostate specific antigen and race using multivariate linear regression. Results: A total of 497 patients with preoperative transrectal ultrasound volume, specimen weight and body mass index data were identified in the Shared-Equal Access Regional Cancer Hospital database. Transrectal ultrasound volume correlated modestly with specimen weights (r = 0.692, p 0.05). However, percent error but not absolute error was significantly predicted by transrectal ultrasound volume (p
