“…Currently, the two most common modalities for prostate imaging and volume measurement are TRUS and MRI (23). The ellipsoid model, which is the original and de facto standard method of calculating prostate volume, uses the formula: transverse diameter×antero-posterior diameter×length×0.52 and assumes that the prostate has a regular ellipsoid shape (24,25). This relatively quick and simple technique can be applied to both ultrasonography and MRI (Figs.…”

Benign prostatic hyperplasia (BPH) is a nonmalignant pathological enlargement of the prostate, which occurs primarily in the transitional zone. BPH is highly prevalent and is a major cause of lower urinary tract symptoms in aging males, although there is no direct relationship between prostate volume and symptom severity. The progression of BPH can be quantified by measuring the volumes of the whole prostate and its zones, based on image segmentation on magnetic resonance imaging. Prostate volume determination via segmentation is a useful measure for patients undergoing therapy for BPH. However, prostate segmentation is not widely used due to the excessive time required for even experts to manually map the margins of the prostate. Here, we review and compare new methods of prostate volume segmentation using both manual and automated methods, including the ellipsoid formula, manual planimetry, and semiautomated and fully automated segmentation approaches. We highlight the utility of prostate segmentation in the clinical context of assessing BPH. Benign prostatic hyperplasia (BPH) can result in lower urinary tract symptoms, and is one of the most common diseases affecting aging men. BPH can compromise quality of life and is a major healthcare cost. Despite the high prevalence of BPH, few methods of accurately assessing prostate volume are actually used in clinical practice. While patient assessment of urinary symptoms dictates the need for treatment, it is highly subjective, whereas prostate volume change is a more objective measure of treatment response. The most common clinical model for approximating the prostate gland size is the ellipsoid model from transrectal ultrasonography (TRUS) imaging, which has been shown to underestimate prostate volume for prostates larger than 50 mL and to overestimate prostate volume for glands smaller than 30 mL (1). Despite its limitations, the TRUS method of prostate volume assessment is preferred in current clinical practice due to its availability and cost and time efficiency (2). More accurate prostate volume measurement with magnetic resonance (MR) planimetry is time-intensive and, thus, rarely performed.Prostate segmentation is an accurate technique for prostate volume determination that can be used in coregistration with various imaging modalities, such as magnetic resonance imaging (MRI) with positron emission tomography and MRI with ultrasonography. Segmentation can be used for both diagnostic and interventional procedures, including guided biopsies and focal ablation. Newly developed methods of automated prostate segmentation allow for efficient prostate volume determination, thereby enhancing decision support systems and computer-aided diagnosis tools.This article reviews the major methods of prostate volume determination currently in use, including the ellipsoid formula, manual planimetry, and semiautomated and fully automated segmentation. A clinical overview of BPH is also provided to highlight the utility of prostate segmentation in the clinical management...

“…According to his study, individual parameters like DWT and PVRU values showed positive and strong correlations with IPSS (Spearman's correlation coefficients were 0.463 and 0.623, respectively). 12 Okele et al also concluded DWT assessment is a better investigation to detect BOO in comparison to PVRU, prostate size and urodynamic studies. 89% results of DWT and PFS were in agreement according to him.…”

“…1 Tokgöz Ö described correlation between IPSS and BWT as significant (r = 0.377). 12 As described IPSS is subjective assessment tool which is extremely dependent on patient's IQ level and literacy, therefore it is very difficult to calculate IPSS accurately. BWT on the other hand is an objective assessment tool which can be easily measured using routine ultrasound KUB.…”

Objectives: Our objective was determination of the correlation between mean bladder wall thickness and mean IPSS in BPH diagnosed patients. Study Design: Cross sectional study. Setting: Department of Urology & Renal Transplantation, Punjab Medical College / Allied Hospital, Faisalabad. Period: Six months from 01-04-2016 to 30-09-2016. Material & Methods: Total 70 patients were enrolled for study from outpatient department of Urology, AHF. IPSS was calculated and recorded. Transabdominal ultrasound KUB was done to measure bladder wall thickness. Urine complete examination and culture was done to rule out UTI. Existence of bladder tumor was ruled out by previous history and ultrasonography. The data was collected on a Proforma by myself. Results: Out of 70 enrolled cases, 47.14% (n=33) were aged 50-60 years whereas 52.86% (n=37) were 61-70 years of age. Mean age was calculated as 61.27+5.31 years. Mean Bladder Wall thickness was 3.64+0.72 and IPSS was calculated to be 12.84+2.79 (r0.9056). Correlation between mean bladder wall thickness and mean IPSS in patients having benign prostatic hyperplasia was calculated as significant. Conclusion: In patients suffering from BOO due to BPH, we have found a very strong positive correlation between mean IPSS and mean BWT. However, bigger studies using standardized techniques are required to establish this fact.

“…However, for the majority of cases in the male population, the etiology is benign prostatic hyperplasia. 3 Post void residual urine was recommended by the Fifth International Consultation for the diagnostic work-up of LUTS especially for patient follow up secondary to benign prostatic hyperplasia. 4 The PVRU is defined as the volume of urine remaining in the bladder immediately after the completion of micturition.…”

Introduction: The Post Void Residual Urine volume (PVRU) is frequently significant in patients with bladder outflow obstruction; especially in patients with enlarged prostate and prostatism. The PVRU forms an important part of radiological investigation. Accurate measurement of the residual urine volume changes observed serially over a period of time may indicate clinical progress. The purpose of this study was to evaluate the effect of pre-void bladder volume on PVRU measurements. Methods: A prospective study was conducted to determine the accuracy of PVRU measurement in patient presenting with lower urinary tract symptoms (LUTS). 50 patients with LUTS were assessed ultrasonographically for pre void and post void bladder volumes during the study period of March 2017 till August 2017. PVRU measurements done in patients with bladder filling sensation at moderate to full capacity resulted in high estimations of PVRU which was quite significant in this study. Results: There was significant difference in the estimated PVRU between patients having high initial premicturitional volume (546±144 ml) than those with lower or moderate filling volume (261±58 ml) with mean of 173 ml and 35 ml respectively. The difference in estimated PVRU was highly significant with p value of < 0.0001. Conclusions: Measurement of pre void urinary bladder volume with an uncomfortably full bladder results in high post micturitional (PMRU) values even in most patients without lower urinary tract symptoms which may be false-positive. We advise that initial or pre-void urine volume be measured when the patient has initial or moderate feeling of bladder fullness.
