“…However, this method does not necessarily determine the true in vivo prostate volume, due to shrinkage because of loss of blood supply, 5 and the volume might also be overestimated because of adjacent periprostatic tissue. 13 Several methodological studies, like measurement of water filled balloons, 14 and cadaver studies 13,15 have demonstrated that under ideal conditions, planimetry measures a volume very close to the true volume, and can be used as the gold standard of prostate volume measurement. 3 However, problems with planimetry measurements include poor visibility of the prostate border and patient movement.…”

We evaluated six alternative methods of prostate volume determination by transrectal ultrasound, three based on planimetry and three based on measurement of prostate diameters. Prostate volume measurements were made on an average of 6.5 occasions over a 3 y period on 41 patients with benign prostatic hyperplasia, using standard techniques. We defined the average of multiple planimetries as the prostate reference volume. Agreement with the reference volume and reproducibility at repeat testing was in the same range for single planimetry and volume determinations based on the formulas height (H)6width (W)6length (L)6p/6 and W6W6H6p/6, but was poorer using the formula W6W6W6p/6. Using the average result of two successive planimetry measurements increased the reproducibility of planimetry, being statistically significantly better than for one single planimetry (P ¼ 0.024) or for the formula W6W6H6p/6 (P ¼ 0.048). Our study suggests that the simple formula based methods of prostate volume determination provide results that are only marginally inferior to one single planimetry, but results are improved by performing two planimetry measurements.

“…3D ultrasonography of the prostate seems to be of additional value for volume measurement of the prostate [36, 37, 38], taking transrectally directed prostate biopsy specimens [39, 40], staging of prostate cancer [41, 42], and follow–up of therapy of prostate cancer [43, 44, 45]. Most authors conclude that 3D ultrasound certainly has potential to be of additional value in certain investigations of the prostate.…”

“…Three-dimensional sonography has been shown to be more reliable and repeatable than gray scale sonography in evaluating anatomic structures and disease entities. [17][18][19] In this study, we showed the feasibility of 3D sonography and virtual sonographic cystoscopy in detection of bladder lesions larger than 5 mm. To our knowledge, a study applying these methods in detection of bladder tumors has not been reported previously.…”

Objective. Bladder tumors are among the most common types of malignant neoplasms of the urinary tract. The purpose of this study was to evaluate the potential value of 3-dimensional (3D) sonography and sonographic cystoscopy in detection of bladder tumors. Methods. Thirty-one patients with suspected or known bladder tumors were included this study. All patients underwent 3D sonography and conventional cystoscopy within 15 days. The number, size, location, and morphologic features of the lesions were evaluated on gray scale, 3D virtual, and multiplanar reconstruction images obtained from the patients. The results of 3D sonographic cystoscopy were compared with the findings from conventional cystoscopy, which was considered the reference standard. Results. Twenty-eight (90.3%) of 31 3D virtual sonographic cystoscopic studies had good or excellent image quality. Conventional cystoscopy revealed 47 lesions in 22 of 28 patients; 3D sonographic virtual cystoscopy showed 41 (87.2%) of 47 lesions. Three-dimensional virtual sonography alone had sensitivity of 96.2%, specificity of 70.6%, a positive predictive value of 93.9%, and a negative predictive value of 80% for tumor detection. The combination of gray scale sonography, multiplanar reconstruction, and 3D virtual sonography had sensitivity of 96.4%, specificity of 88.8%, a positive predictive value of 97.6%, and a negative predictive value of 84.2% for tumor detection. Conclusions. Three-dimensional sonography is a promising alternative noninvasive technique for use in detection of bladder tumors, their localization, and perivesical spreading. The location, size, and morphologic features of the tumors shown on 3D sonography agreed well with the findings of conventional cystoscopy.

Radiology (E.K., A.K., A.K.P., H.A.) ladder tumors are among the most common neoplasms of the urinary tract, accounting for 6% of all malignancies in men and 2% of those in women. 1 In the United States, it is the 7th leading cause of cancer death in men and the 10th in women.
