“…The transitional zone volume measured by transrectal ultrasound correlated good (r=0.87 30 to r=0.97 33 52 ) with enucleated tissue weight, and subgrouping for men with a larger prostate size slightly increased the correlation. 30 Correlations with transrectal ultrasound measured total prostate volume were good (r=0.82 21 and r=0.96 33 ). Good sensitivity (93%) and fair specificity (61%) to identify volumes under 80 cc with a specimen weight under 80 grams were found.…”

“…Then, full-text screening was performed for 152 studies, of which 61 studies met all selection criteria and were scored using the COSMIN checklist. Subsequently, 37 studies received a COSMIN score of fair, good or excellent 21–57. Twenty-four studies58–81 received ‘poor’ COSMIN scores and were therefore excluded from the best evidence synthesis.…”

ObjectivesTo systematically review the literature regarding the reliability and validity of assessment methods available in primary care for bladder outlet obstruction or benign prostatic obstruction in men with lower urinary tract symptoms (LUTS).DesignSystematic review with best evidence synthesis.SettingPrimary care.ParticipantsMen with LUTS due to bladder outlet obstruction or benign prostatic obstruction.Review methodsPubMed, Ebsco/CINAHL and Embase databases were searched for studies on the validity and reliability of assessment methods for bladder outlet obstruction and benign prostatic obstruction in primary care. Methodological quality was assessed with the COSMIN checklist. Studies with poor methodology were excluded from the best evidence synthesis.ResultsOf the 5644 studies identified, 61 were scored with the COSMIN checklist, 37 studies were included in the best evidence synthesis, 18 evaluated bladder outlet obstruction and 17 benign prostatic obstruction, 2 evaluated both. Overall, reliability was poorly evaluated. Transrectal and transabdominal ultrasound showed moderate to good validity to evaluate bladder outlet obstruction. Measured prostate volume with these ultrasound methods, to identify benign prostatic obstruction, showed moderate to good accuracy, supported by a moderate to high level of evidence. Uroflowmetry for bladder outlet obstruction showed poor to moderate diagnostic accuracy, depending on used cut-off values. Questionnaires were supported by high-quality evidence, although correlations and diagnostic accuracy were poor to moderate compared with criterion tests. Other methods were supported by low level evidence.ConclusionClinicians in primary care can incorporate transabdominal and transrectal ultrasound or uroflowmetry in the evaluation of men with LUTS but should not solely rely on these methods as the diagnostic accuracy is insufficient and reliability remains insufficiently researched. Low-to-moderate levels of evidence for most assessment methods were due to methodological shortcomings and inconsistency in the studies. This highlights the need for better study designs in this domain.

“…Lower urinary tract symptoms (LUTS) were evaluated by the International Prostate Symptom Score (IPSS) and the Quality of Life (QoL) score based on status over the previous month before hospital admission. The prostate volume was assessed using transrectal ultrasonography ( 12 ). Owing to indwelling catheters, the patients did not undergo testing of the urinary flow rate or post-void residual urine volume (PVR) before surgery.…”

Purpose: Benign prostatic hyperplasia-associated massive hemorrhage is a urological emergency. We evaluated the outcome from immediate transurethral plasma kinetic enucleation of the prostate gland (i-TUPKEP) for BHM treatment.Methods: We retrospectively analyzed the records of 49 patients with acute BMH who underwent i-TUPKEP between January 2014 and November 2018 at our institution. The hemostatic effect, International Prostate Symptom Score (IPSS), and quality of life (QoL) score were evaluated preoperatively as well as 3, 6, and 12 months postoperatively. Postoperative follow-up also included measurement of the peak flow rate (Qmax) and post-void residual urine volume (PVR). Clinical characteristics, weight of resected tissue, duration of bladder irrigation, duration of hospital stay, complications, as well as the time required for enucleation and resection, were recorded.Results: BMH causes were attributed to transurethral surgery (17/49, 34.7%), violent catheterization (13/49, 26.5%), cystoscopy (10/49, 20.4%), and urethral dilatation (9/49, 18.4%). Bleeding was from different sites of prostate-gland tissues during i-TURKEP. i-TUPKEP-controlled BMH effectively induced immediate, notable, and lasting improvements in the IPSS and QoL score. Qmax was close to normal, and the PVR was within the physiological range, postoperatively. Long-term complications were not observed.Conclusion: Our preliminary data suggest that i-TUPKEP is a feasible method for controlling BHM and relieving BPH symptoms.

“…To date, only one study has measured PUT. The PUT was measured as 6 [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] mm in a study by Guneyli et al (29). However, the median (IQR) value of PUT was measured as 11.63 (6.91-17.41) mm in this study.…”

“…Although these changes have been measured in 2D planes (3)(4)(5), the degree of which the prostatic urethra is compressed by the prostate and the angle relationship between prostate urethral and bladder have not been investigated. Prostate volume (PV) has attracted considerable attention in 2D planes (6). However, it is difficult to measure intravesical prostatic volume (IPPV), intravesical prostatic thickness (IPPT) and intravesical prostatic protrusion surface area (IPPS).…”

Background: The volume and thickness of intravesical prostatic protrusion and other characteristics of benign prostatic hyperplasia have not been investigated. We determine the effects of age and prostate volume on anatomical features of benign prostatic hyperplasia using three-dimensional measurement in this study.Methods: This retrospective study included a total of 98 patients with benign prostatic hyperplasia. Threedimensional models of prostate, central gland, peripheral zone, intravesical prostatic protrusion, prostatic urethra and bladder were reconstructed according to pelvic T2-weighted magnetic resonance imaging of these patients. The models were used to measure the intravesical prostatic protrusion volume, intravesical prostatic protrusion thickness, intravesical prostatic protrusion index, intravesical prostatic protrusion, prostate volume, peripheral zone volume, peripheral zone thickness, peripheral zone index, prostatic urethra thickness, the angle and distance of distal prostatic urethra with regard to coronal plane and sagittal plane and so on.Results: Intravesical prostatic protrusion volume, intravesical prostatic protrusion thickness and peripheral zone volume of prostate volume >80 mL group were significantly higher than these in prostate volume <80 mL group (P<0.001, 0.01, 0.01, respectively). These parameters significantly increased with age (P<0.001, 0.01, 0.05, respectively). Peripheral zone index was significantly lower of prostate volume >80 mL group than these in prostate volume <80 mL group (P<0.05). Peripheral zone index significantly decreased with age (P<0.01). Intravesical prostatic protrusion index had no significant difference in all age groups. Peripheral zone thickness and prostatic urethra thickness had no significant difference in all groups. The distance and angle of distal prostatic urethra prostatic urethra with regard to coronal plane were significantly higher than these with regard to sagittal plane (both P<0.001). Conclusions:The rearward slope of the prostatic urethra is greater than the left or right offset during the process of benign prostatic hyperplasia. Three-dimensional measurement provides good supports for further clinical and scientific research.
