![]() Thus, we aimed to compare the two methods of obtaining the height of prostate to determine which assessment of height is more accurate and useful for diagnosis of BPH.Ī total of 968 patients who underwent TRUS for diagnosis of any diseases related to the prostate from October 2012 to May 2013 were included in this study prospectively. However, they describe at the same time in the figure legend that it is measured on the sagittal plane. Even in the 9th edition of Campbell-Walsh Urology, the textbook of urology, the authors describe in the text that the anteroposterior diameter (height) of the prostate is measured on the axial plane. It remains controversial which method is more accurate for measuring prostate volume. It can be obtained on two planes, axial and sagittal. Meanwhile, height refers to the anteroposterior diameter of the prostate. ![]() It is obtained by calculating the maximal transverse diameter at the midgland level of the prostate. Also, width refers to the transverse diameter of the prostate. It is obtained by calculating the distance from the proximal external sphincter to the urinary bladder. Length refers to the longitudinal diameter of the prostate. It is calculated as follows: prolate ellipse volume (cm)=(length×width×height)×π/6. ![]() Among them, prolate ellipse volume calculation is commonly used because it is fast and precise. ![]() Three techniques are used to measure prostate volume: planimetry calculation, prolate ellipse volume calculation, and ellipsoid volume measurement. TRUS is useful in that it can evaluate the size, shape, presence of adenoma, and anatomy of the prostate relatively accurately and noninvasively. Many urologists routinely use transrectal ultrasonography (TRUS) to diagnose BPH. Because BPH can lower the quality of life, active diagnosis and treatment are now being conducted. Benign prostatic hyperplasia (BPH) is common in middle-aged men, is found in over half of 60-year-old men, and is found in almost all 80-year-old men. ![]()
