Transrectal ultrasonic volumetry of the prostate: In vivo comparison of different methods
TLDR
In order to assess the accuracy of various volumetric methods for screening and follow‐up of prostatic disease, total prostate volume and inner zone volume were measured by transrectal ultrasonography in a screening population of 716 men.Abstract:
In order to assess the accuracy of various volumetric methods for screening and follow-up of prostatic disease, total prostate volume and inner zone volume were measured by transrectal ultrasonography in a screening population of 716 men Semiplanimetric and caliper formula methods were compared with step section planimetry as the gold standard Planimetric volumetry of the prostate is regarded as the most reproducible method for individual follow-up of total gland and inner zone volume The prorate spheroid formula is the most reproducible of caliper formula methods for both volumes In this study the elliptical volume was, however, more accurate than the prorate spheroid volume of the total gland, as the correlation coefficient between total elliptical volume and planimetry was higher compared to the prorate spheroid volume (089 vs 083), and the standard deviation of the mean volumetric difference smaller The mean total prorate spheroid volume resembled the mean total planimetric volume better than the elliptical volume did, as the mean volumetric difference was smaller For measurement of the inner zone volume the prorate spheroid volume was more accurate than the elliptical volume The correlation coefficient between length and planimetric volume was similar to that of width and height, which accounted for more accuracy of the elliptical volume than of the prorate spheroid volume in larger prostates The elliptical volume might be used for incidental volumetric measurements of the total gland, and for comparison of different individuals, e g, in preoperative evaluation or screening studiesread more

TL;DR: Different histological variables associated to BPH are differently influenced by the age of patients and prostate volume, and they differently influence serum PSA levels.

TL;DR: The mean transition zone volume (TZV) had a higher increase rate with age than the mean total prostate volume (TPV), indicating that the enlargement of the TZ contributed the most to the increase in TPV.

Serum Prostate-Specific Antigen as a Predictor of Prostate Volume in the Community: The Krimpen Study
TL;DR: In men for whom a diagnosis of PCa has been ruled out, PSA can be used to detect an enlarged prostate (>30 cc and with more accuracy PV>40 or 50 cc) and more precision in estimating PV can be obtained when using a formula that contains PSA, age, DRE and an interaction term between age and PSA.

Comparison of prostate volume measured by transrectal ultrasonography and MRI with the actual prostate volume measured after radical prostatectomy.
TL;DR: Between two TRUS volumes, TR US-V1 was shown to be superior to TRUS-V2, and in MRI, MRI-EV2 was more accurate than MRI- EV1, however,MRI-PV was the most accurate method.

Normal histology of the prostate.
TL;DR: The prostate gland contains three major glandular regions--the peripheral zone, the central zone, and the transition zone--which differ histologically and biologically, and which may at times be confused with carcinoma, especially in biopsy material.

Determination of prostate volume by transrectal ultrasound.
TL;DR: The most accurate method to estimate prostate weight was a variation of the prolate spheroid formula, expressed as pi/6 (transverse dimension)2 (anteroposterior dimension), which provided the closest estimate of weight in glands of less than 40 gm.

TL;DR: Although less accurate than planimetry, HWL is a rapid volume measurement technique that appears to be more accurate than ellipsoid software packages; its universal availability makes it practical for routine clinical use.

Estimation Of Prostate Cancer Volume By Transrectal Ultrasound Imaging
TL;DR: Most of the sonographic methods that have proved to be useful for estimation of prostate gland volume were inaccurate in estimation of the cancer volume in the prostatectomy specimen, and ultrasound imaging alone does not appear to be a useful means to predict cancer volume.

Ultrasonically determined patterns of enlargement in benign prostatic hyperplasia.
TL;DR: A reproducible method of prostate volume estimation is described and the implications of prostate dimension changes in BPH are discussed and a proportionally greater increase in the APD compared with L and TD and by an increasing adenoma/prostate ratio are discussed.
