“…Rather, 3-dimensional parameters of prostate such as maximal width and A-P diameter were measured and subsequently applied in a prolate ellipsoid volume formula to come up with prostate volumes [17] . Some have weighed prostate removed from surgery and calculated the volume by considering factors such as specific gravity of prostate and subtracting the weight of seminal vesicles [14,18] . Meanwhile, others have measured prostate volumes by placing prostates in water-filled container as done in our study [6] .…”

Aim: To compare the prostate volume, as measured by transrectal ultrasonography (TRUS) and by MRI, with that of the actual prostate volume measured after a radical prostatectomy (RRP). Materials and Methods: This prospective study included 21 patients who had undergone RRP. TRUS prostate volumes were calculated using the prolate ellipsoid volume formula, with the anteroposterior diameter measured from axial (TRUS-V1) and mid-sagittal images (TRUS-V2). Two prolate ellipsoid volumes (MRI-EV1 and MRI-EV2) were calculated from the MRI using the same method, and planimetric volume (MRI-PV). The actual prostate volume (Actual-V) was measured in a measuring jug within 1 h after RRP. Results: Mean of Actual-V was 40.3ml (21.0–82.0). In paired sample tests, the correlation coefficients (R) for all methods were over 0.8. In a Student’s t test (paired), MRI-PV (p = 0.620), MRI-EV2 (p = 0.703) and TRUS-V1 (p = 0.099) showed no significant differences compared to the Actual-V. The linear regression models of these three methods were y = 1.025x – 0.268, y = 0.946x + 2.979 and y = 1.046x + 0.381, respectively. Conclusions: Between two TRUS volumes, TRUS-V1 was shown to be superior to TRUS-V2. In MRI, MRI-EV2 was more accurate than MRI-EV1. However, MRI-PV was the most accurate method. TRUS-V1 and MRI-EV2 could be used instead of MRI-PV in general clinical settings.

“…Even though prostate volume was calculated postoperatively according to the pathological prostate dimensions, there is a high positive correlation between preoperative (during transrectal ultrasound) and postoperative calculation of prostate volume. 12 Statistical analysis was performed by using SPSS version 17 (SPSS Inc, Chicago, IL). The descriptive statistics are presented as the mean ± standard deviation (SD) and interquartile range (IQR) for continuous variables and as the absolute and percent frequency for categorical variables.…”

AbstractBackground: Focal hemiablative therapy for prostate cancer is a new treatment alternative. Unilateral and unifocal disease are its main limitations. The aim of this study was to identify the epidemiological, clinical and pathological parameters that may predict unilateral disease in patients diagnosed with prostate cancer. Methods:We performed a retrospective analysis of patients at our institution between January 2005 and January 2011. Only patients with unilateral disease in prostate biopsy were part of the study. The analysis included age, preoperative prostate-specific antigen (PSA) and its density, prostate volume, biopsy first and second Gleason pattern and Gleason summary, number of biopsy cores, percentage of cancer in biopsy material and the presence of highgrade prostatic intraepithelial neoplasia. Their role as potential predictors was evaluated by univariate and multivariate analysis. Results: A total of 161 patients had unilateral disease after prostate biopsy. A significant correlation was found between prostate volume, PSA density and percentage of cancer in biopsy material and the presence of unilateral disease in the surgical specimen. These are the same factors significant in the univariate analysis. The results of the multivariate analysis demonstrated that PSA density (p = 0.015) and percentage of cancer in biopsy material (p = 0.028) are the most significant predictors. Interpretation: Our results demonstrate that PSA density and the percentage of cancer in biopsy cores are significant predictors for prostate cancer unilaterality and should be considered for the selection of hemiablative focal therapy candidates.

“…PSA density was calculated by dividing the preoperative PSA value and prostate volume. Even thought prostate volume was calculated postoperatively according to the prostate dimensions given by the pathologists report, there is a great positive correlation between preoperative (during transrectal ultrasound) and postoperative calculation of prostate volume (Wolff et al, 1995).…”
