Abstract
BACKGROUND The International Prostate Symptom Score (IPSS) is a patient-reported measurement to assess the lower urinary tract symptoms of bladder outlet obstruction. Bladder outlet obstruction induces molecular and morphological alterations in the urothelium, suburothelium, detrusor smooth muscle cells, detrusor extracellular matrix, and nerves. We sought to analyze MRI-based radiomics features of the urinary bladder wall and their association with IPSS. METHOD In this retrospective study, 87 patients who had pelvic MRI scans were identified. A biomarker discovery approach based on the optimal biomarker (OBM) method was used to extract features of the bladder wall from MR images, including morphological, intensity-based, and texture-based features, along with clinical variables. Mathematical models were created using subsets of features and evaluated based on their ability to discriminate between low and moderate-to-severe IPSS (less than 8 vs. equal to or greater than 8). RESULTS Of the 7,666 features per patient, four highest-ranking optimal features were derived (all texture-based features), which provided a classification accuracy of 0.80 with a sensitivity, specificity, and area under the receiver operating characteristic curve of 0.81, 0.81, and 0.87, respectively. CONCLUSION A highly independent set of urinary bladder wall features derived from MRI scans were able to discriminate between patients with low vs. moderate-to-severe IPSS with accuracy of 80%. Such differences in MRI-based properties of the bladder wall in patients with varying IPSS's might reflect differences in underlying molecular and morphological alterations that occur in the setting of chronic bladder outlet obstruction.

Abstract
Benign prostatic hyperplasia (BPH) is the most common disease of the lower urinary tract in men. The prevalence increases continuously with increasing age and a chronic progressive course is to be expected. In order to reduce the morbidity of affected patients and to improve their quality of life, the expert panel Benign Prostatic Hyperplasia (BPH) of the German Society of Urology (DGU) has written a new version of the evidence-based "S2e guideline on the diagnosis and treatment of BPH". Using a current patient case, the contents of the new S2e guideline are illustrated, from diagnosis to the decision-making process for a suitable treatment choice. The case presented here shows the possible complexity and difficulty that can arise in the diagnosis of BPH, the need for further diagnostic steps and the finding of a suitable therapy in order to fulfill the patient's wishes, if possible.

Cheng Y, Li T, Wu X, Du G, Xu S. A novel predictive model for noninvasively diagnosing bladder outlet obstruction in female patients based on clinical features and uroflowmetry parameters. Int J Gynaecol Obstet 2024. [PMID: 38415782 DOI: 10.1002/ijgo.15430] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 10/17/2023] [Accepted: 01/30/2024] [Indexed: 02/29/2024]
Abstract
OBJECTIVE To develop and validate a simple prediction model to diagnose female bladder outlet obstruction (fBOO) because of the invasive nature of standard urodynamic studies (UDS) for diagnosing fBOO. METHODS We retrospectively analyzed the data of 728 women who underwent UDS at Tongji Hospital between 2011 and 2021. The definition of fBOO was Pdet.Qmax - 2.2 × Qmax > 5 (BOOIf > 5). Independent predictive factors of fBOO were determined by multivariable logistic regression analysis. These predictive factors were incorporated into a predictive model to assess the risk of fBOO. RESULTS Of the 728 patients, 249 (34.2%) were identified as having fBOO and these women were randomly assigned to two groups, a model development group and a model validation group. Multivariate logistic regression demonstrated that age, Qmax , flow time, and voiding efficiency were independent risk factors for fBOO. The predictive model of fBOO showed a satisfactory performance, with area under the curve being 0.811 (95% confidence interval [CI] 0.771-0.850, P < 0.001), which was confirmed to be 0.820 (95% CI 0.759-0.882, P < 0.001) with external validation. The calibration curve indicated that the predicted probability had an excellent correspondence to observed frequency. Decision curve analysis demonstrated a greater clinical net benefit compared with the strategies of treat all or treat none when the predicted risk was in a range of 3% and 75%. CONCLUSION A novel predictive model of fBOO was developed and validated based on clinical features and noninvasive test parameters in female patients with lower urinary tract symptoms. The model is a quick and easy-to-use tool to assess the risk of fBOO for urologists in their routine practice without an invasive UDS.

Medical Treatment Incidence and Persistence After Surgical Relief of Lower Urinary Tract Symptoms Suggestive of Benign Prostatic Obstruction: A Critical Analysis of the Literature. Eur Urol Focus 2023:S2405-4569(23)00193-1.

Abstract
CONTEXT The incidence and risk factors for persisting pharmacotherapy following surgical treatment of benign prostatic obstruction (BPO) remain unclear. OBJECTIVE To evaluate the evidence on persisting pharmacotherapy of lower urinary tract symptoms (LUTS) following surgical treatment of BPO. EVIDENCE ACQUISITION A systematic review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses checklist (PROSPERO ID CRD42022310598). PubMed and EMBASE databases were searched in February 2022, with an updated search in October 2022. Studies evaluating pharmacotherapy in men aged >18 yr following surgical treatment of BPO were included. EVIDENCE SYNTHESIS Overall, ten nonrandomized studies and one post hoc analysis of two randomized controlled trials were included. The incidence of persisting medical treatment or medical retreatment varied strongly between time points and investigated surgical techniques. Among the investigated techniques, most data were available for transurethral resection of the prostate (TURP). Persistence of pharmacotherapy after TURP at 6 mo ranged from 8.7% to 57% for the use of alpha-blockers. The use of 5-alpha reductase inhibitors after TURP ranged from 5.5% at 6 mo to 19% at 6-24 mo, whereas the use of antimuscarinics ranged from 3.4% to 28.1% at 6 mo. Data on initiation of pharmacotherapy after TURP also differed between study and type of medication. At 12 yr, the use of alpha-blockers after TURP ranged from 12% to 38%. The risk factors associated with medication after BPO surgery were age, history of diabetes mellitus, history of cerebrovascular accident, preoperative medication use, as well as surgical techniques other than laser enucleation of the prostate. CONCLUSIONS Pharmacotherapy for LUTS is common after BPO surgery. The outcomes following different surgical techniques are heterogeneous, with limited data from randomized controlled trials. Future studies on surgical treatment of BPO should include the use of LUTS-related pharmacotherapy after BPO surgery as a secondary endpoint. PATIENT SUMMARY In the present systematic review, we investigated the risk of ongoing or novel therapy with drugs following surgery for benign prostate enlargement. We found that a non-negligible proportion of men will need to take drug therapy after surgery. Certain risk factors can be identified, which are associated with a higher risk of drug therapy after surgery.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH; in German guidelines: benign prostatic syndrome [BPS]) is the most frequent urological disease in men and can result in a considerable deterioration of quality-of-life. BPS can be associated with LUTS, benign prostatic enlargement (BPE), and bladder outlet obstruction (BOO) or benign prostatic obstruction (BPO), respectively. The expert group on BPS of the German Society of Urology has re-evaluated the tests for the assessment of BPH and provides evidence-based recommendations. OBJECTIVES Presentation and evidence-based rating of tests for the assessment of patients with BPS. MATERIALS AND METHODS Summary and overview of chapters 5, 6, and 8 of the latest long version of the German S2e guideline on BPS. RESULTS The diagnostic work-up should clarify (1) whether the complaints of the patient are caused by BPS, (2) how relevant the complaints are and whether treatment is necessary, (3) whether complications of the lower or upper urinary tract already exist, and (4) which treatment will be most suitable. Baseline assessment should be done in all BPS patients and include history, measurement of LUTS and quality-of-life, urinalysis, serum prostate-specific antigen, post-void residual, ultrasound of the lower urinary tract, including measurements of prostate volume, intravesical prostatic protrusion and detrusor wall thickness, and ultrasound of the upper urinary tract. Additional tests can follow when questions remain unanswered after baseline assessment. These optional tests include bladder diaries, uroflowmetry, serum creatinine, urethrocystoscopy, other noninvasive tests for the determination of BOO/BPO such as penile cuff test, condom catheter method and near-infrared spectroscopy, and other imagining tests such as X‑ray and MRI investigations. CONCLUSIONS The updated German S2e guideline summarizes evidence-based recommendations on the diagnostic work-up, including the assessment of the BPS components BPE, LUTS, and BOO/BPO.

Abstract
Lower urinary tract symptoms (LUTS) is a broad term that covers a range of urinary issues, which are often categorised as storage and voiding symptoms. Storage symptoms include increased frequency, nocturia, urgency and urge incontinence, while voiding symptoms include hesitancy, suboptimal flow, dribbling and incomplete emptying. In men, the most common causes of LUTS are benign prostatic hyperplasia (prostate enlargement) and overactive bladder. This article provides an overview of the anatomy of the prostate and outlines the assessment process for men presenting with LUTS. It also explains the recommended lifestyle modifications, medicines and surgical interventions available to male patients who are experiencing these symptoms.

Abstract
PURPOSE To investigate whether circulating adiponectin, which is considered a possible marker of anti-atherogenic effects, is a useful predictor of bladder function, especially detrusor underactivity (DU), in men with lower urinary tract symptoms (LUTS). METHODS A total of 130 treatment-naïve men with non-neurogenic LUTS were prospectively stratified into two groups (the DU and non-DU groups) based on the presence or absence of DU, where DU is defined as a bladder contractility index < 100 and bladder outlet obstruction index (BOOI) < 40. The impact of serum adiponectin levels on urodynamic function, including DU, was assessed using univariate, binomial logistic regression, and receiver operating characteristic (ROC) curve analyses. RESULTS In total, data from 118 men were analyzed; 39 (33.0%) had DU (DU group) and 79 (67.0%) did not have DU (non-DU group). The median serum adiponectin in the DU group was significantly lower than in the non-DU group (6.2 vs 12.6 µg/mL, p < 0.001). In the binomial logistic regression analysis, lower adiponectin, smaller intravesical prostatic protrusion, and lower bladder voiding efficiency were significant factors related to DU. In the ROC analyses, serum adiponectin had the highest area under the curve value for DU diagnosis (0.849). Additionally, a cutoff value of 7.9 µg/mL for serum adiponectin level was identified for DU, which yielded a sensitivity and specificity of 79% and 90%, respectively. CONCLUSIONS The serum adiponectin level was significantly associated with bladder function and may be a useful marker for predicting DU in men with LUTS.

Abstract
AIMS The aim of this study was to compare the clinical characteristics of men with lower urinary tract symptoms (LUTS) grouped by 24-h urine output determined from a bladder voiding diary. METHODS An online database was queried to identify men who completed a 24-hour bladder diary (24HBD), and the Lower Urinary Tract Symptom Score (LUTSS) questionnaire from 2015 to 2019 using a mobile app. Data from the bladder diary and questionnaire were contemporaneously matched within a 2-week period. Additional data, including maximum uroflow (Qmax ) and postvoid residual urine (PVR), were obtained from the electronic medical record (EMR). The cohort was divided into three groups: normal, oliguria, and polyuria based on their 24-hour voided volume (24HVV). The LUTSS, 24HVV, maximum voided volume (MVV), maximum flow rate (Qmax ), and PVR were compared between those with oliguria and polyuria. RESULTS A total of 327 men (mean age 62, SD: 19) completed the LUTSS questionnaire and contemporaneous 24HBD. Of these, 61% had a normal 24HVV, 13% had oliguria, and 26% had polyuria. A total of 147 patients from the study cohort had contemporaneous Qmax and PVR abstracted from the EMR. There was no difference in symptom severity, bother, or PVR among the three patient groups. However, several objective metrics were significantly correlated with urine output. Men with oliguria, as compared to men with polyuria were older (65 vs. 55 years) and had lower MVV (260 vs. 470 mL), fewer voids/24 h (8 vs. 13), and lower Qmax (8.5 vs. 18.3 mL/s). CONCLUSIONS These observations suggest that men with oliguria or polyuria and LUTS constitute easily distinguished phenotypes that might require different diagnostic and therapeutic algorithms. Those with oliguria were older, and had lower MVVs and much lower uroflows, suggesting that they are more likely to have underlying disorders such as bladder outlet obstruction and detrusor underactivity or may be patients with overactive bladder who reduced fluid intake to improve symptoms.

The diagnostic value of non-invasive methods for diagnosing bladder outlet obstruction in men with lower urinary tract symptoms: A meta-analysis. Front Surg 2022; 9:986679. [PMID: 36338622 PMCID: PMC9632994 DOI: 10.3389/fsurg.2022.986679] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 09/05/2022] [Indexed: 11/26/2022] Open
Abstract
Purpose We conducted the first meta-analysis to determine the diagnostic value of non-invasive methods for diagnosing bladder outlet obstruction (BOO) in men with lower urinary tract symptoms (LUTS). Methods We searched a range of databases for relevant publications up to June 2022, including PubMed, Embase, Web of Science, and the Cochrane Library. Retrieved studies were then reviewed for eligibility and data were extracted. The risk of bias (RoB) was assessed using the QUADAS-2 tool. We then performed a formal meta-analysis to evaluate the accuracy of various non-invasive methods for diagnosing BOO in men. Results We identified 51 eligible studies including 7,897 patients for meta-analysis. The majority of the studies had a low overall RoB. Detrusor wall thickness (DWT) (pooled sensitivity (SSY): 71%; specificity (SPY): 88%; diagnostic odds ratio (DOR): 17.15; area under curve (AUC) 0.87) and the penile cuff test (PCT) (pooled SSY: 87%; SPY: 78%; DOR: 23.54; AUC: 0.88) showed high accuracy for diagnosing BOO. Furthermore, data suggested that DWT had the highest pooled SPY (0.89), DOR (32.58), and AUC (0.90), when using 2 mm as the cut-off. Conclusion Of the non-invasive tests tested, DWT and PCT had the highest levels of diagnostic accuracy for diagnosing BOO in men with LUTS. DWT, with a 2 mm cut-off, had the highest level of accuracy. These two methods represent good options as non-invasive tools for evaluating BOO in males.

Prostate Surgery for Men with Lower Urinary Tract Symptoms: Do We Need Urodynamics to Find the Right Candidates? Exploratory Findings from the UPSTREAM Trial. Eur Urol Focus 2022; 8:1331-1339. [PMID: 34922898 PMCID: PMC9705260 DOI: 10.1016/j.euf.2021.11.010] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 10/21/2021] [Accepted: 11/30/2021] [Indexed: 12/16/2022]
Abstract
BACKGROUND Identifying men whose lower urinary tract symptoms (LUTS) may benefit from surgery is challenging. OBJECTIVE To identify routine diagnostic and urodynamic measures associated with treatment decision-making, and outcome, in exploratory analyses of the UPSTREAM trial. DESIGN, SETTING, AND PARTICIPANTS A randomised controlled trial was conducted including 820 men, considering surgery for LUTS, across 26 hospitals in England (ISCTRN56164274). INTERVENTION Men were randomised to a routine care (RC) diagnostic pathway (n = 393) or a pathway that included urodynamics (UDS) in addition to RC (n = 427). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Men underwent uroflowmetry and completed symptom questionnaires, at baseline and 18 mo after randomisation. Regression models identified baseline clinical and symptom measures that predicted recommendation for surgery and/or surgical outcome (measured by the International Prostate Symptom Score [IPSS]). We explored the association between UDS and surgical outcome in subgroups defined by routine measures. RESULTS AND LIMITATIONS The recommendation for surgery could be predicted successfully in the RC and UDS groups (area under the receiver operating characteristic curve 0.78), with maximum flow rate (Qmax) and age predictors in both groups. Surgery was more beneficial in those with higher symptom scores (eg, IPSS >16), age <74 yr, Qmax <9.8 ml/s, bladder outlet obstruction index >47.6, and bladder contractility index >123.0. In the UDS group, urodynamic measures were more strongly predictive of surgical outcome for those with Qmax >15, although patient-reported outcomes were also more predictive in this subgroup. CONCLUSIONS Treatment decisions were informed with UDS, when available, but without evidence of change in the decisions reached. Despite the small group sizes, exploratory analyses suggest that selective use of UDS could detect obstructive pathology, missed by routine measures, in certain subgroups. PATIENT SUMMARY Baseline clinical and symptom measurements were able to predict treatment decisions. The addition of urodynamic test results, while useful, did not generally lead to better surgical decisions and outcomes over routine tests alone.

Modification of bladder thermodynamics in stress urinary incontinence patients submitted to trans-obturator tape: A retrospective study based on urodynamic assessment. Front Bioeng Biotechnol 2022; 10:912602. [PMID: 36061421 PMCID: PMC9437260 DOI: 10.3389/fbioe.2022.912602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 07/11/2022] [Indexed: 11/13/2022] Open
Abstract
Importance: It needs to be clarified whether trans-obturator tape (TOT)-enhanced urethral resistance could impact the voiding function.Objective: Although TOT has been well-recognized for enhancing urethral resistance to restore continence in stress urinary incontinence (SUI) patients, whether the bladder’s voiding functions adapt to the TOT-enhanced resistance has not been adequately investigated. This study thereby aimed to investigate whether TOT impacts the bladder’s thermodynamic efficacy during the voiding phase.Design: A retrospective analysis of urodynamics performed before and after TOT was assessed.Setting: A tertiary referral hospital in Taiwan.Participants: A total of 26 female SUI patients who underwent urodynamic investigations before and after TOT.Main outcomes and measures: The area enclosed by the pressure-volume loop (Apv), which represents the work performed by the bladder during voiding, in a pressure-volume analysis established by plotting the detrusor pressure versus intra-vesical volume was retrospectively analyzed. Paired Student’s t-tests were employed to assess the difference in values before and after the operation. Significance in difference was set at p < 0.05.Results: TOT increased Apv in 20 of 26 (77%) patients and significantly increased the mean Apv compared to the preoperative control (2.17 ± 0.18 and 1.51 ± 0.13 × 103 cmH2O-ml, respectively p < 0.01). TOT also increased the mean urethral resistance (1.03 ± 0.30 vs. 0.29 ± 0.05 cmH2O-sec/ml, p < 0.01) and mean voiding pressure (25.87 ± 1.72 and 19.30 ± 1.98 cmH2O p < 0.01) but did not affect the voided volume and voiding time. Moreover, the TOT-induced Apv increment showed a moderate correlation with the changes in urethral resistance and voiding pressure (both r > 0.5) but no correlation with changes in voided volume or voiding time. It is remarkable that the TOT-induced urethral resistance increment showed a strong correlation with changes in voiding pressure (r > 0.7).Conclusion and Relevance: The bladder enhances thermodynamic efficacy by adapting the voiding mechanism to increased urethral resistance caused by TOT. Further studies with higher case series and longer follow-ups should assess whether this effect could be maintained over time or expire in a functional detrusor decompensation, to define diagnostic criteria that allow therapeutic interventions aimed at its prevention during the follow-up.Clinical Trial Registration: (clinicaltrials.gov), identifier (NCT05255289)

Abstract
OBJECTIVES To 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). DESIGN Systematic review with best evidence synthesis. SETTING Primary care. PARTICIPANTS Men with LUTS due to bladder outlet obstruction or benign prostatic obstruction. REVIEW METHODS PubMed, 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. RESULTS Of 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. CONCLUSION Clinicians 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.

Abstract
AIMS We aimed to investigate the accuracy of bladder sonomorphological parameters including detrusor wall thickness (DWT) and ultrasound-estimated bladder weight (UEBW) for diagnosing bladder outlet obstruction (BOO) in patients with lower urinary tract symptoms (LUTS). METHODS A comprehensive search was conducted through databases including PubMed, EMBASE, MEDLINE, Cochrane Library, Medicine, China Knowledge Network (CNKI), China Biomedical Literature Database, Wanfang Database, the Chongqing VIP Chinese Science, and Technology Periodical Database (VIP) to select studies assessing the diagnostic accuracy of DWT and UEBW to diagnose BOO in adults with LUTS. Databases were searched from inception to 2020 without restriction. Study quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2), and measures of accuracy were calculated using random-effects model. RESULTS The initial search included 84 publications, of which 78 publications were screened, and 16 studies with 1,847 patients finally contained diagnostic data. The results from 10 out of 16 studies assessing DWT showed a pooled sensitivity (SSY) of 0.68 (95% CI, 0.56-0.78) and specificity (SPY) of 0.91 (95% CI, 0.82-0.96) with I2 values of 93%, while 6 studies evaluating UEBW were analyzed with a SSY of 0.88 (95% CI, 0.78-0.93) and SPY of 0.81 (95% CI, 0.67-0.90) with I2 values of 83%. CONCLUSIONS DWT shows high SPY, and UEBW performs high SSY of diagnosing BOO. Further well-designed studies are needed to evaluate the utilization of DWT and UEBW for the diagnosis of BOO.

Abstract
INTRODUCTION Detrusor thickness (DT) and intravesical prostatic protrusion (IPP) are closely related to bladder outlet obstruction. The aim of our study was to look for correlation between DT, IPP and maximum urinary flow (Qmax). METHODS It is a prospective, observational study including men over fifty managed for benign prostatic hyperplasia. Low urinary tract symptoms were assessed with the International Prostatic Symptom Score (IPSS). Pelvic ultrasound was performed for all patients measuring prostatic volume, bladder volume, post- void residual, DT and IPP. Uroflowmetry was performed for all patients, Qmax was noted. Qmax equal or less than 15ml/s was considered pathologic. RESULTS Sixty patients were included for our study. Strong negative correlation was noted between DT, IPP and Qmax (r=-0.59, r=-0.61 respectively). Patients with pathologic Qmax had higher DT and IPP than those with normal Qmax, the difference was significant (P<0.01). Threshold values predicting pathologic Qmax were 3mm for DT and 7mm for IPP. ROC analysis reveals for DT an AUC of 0.84 (95% CI 0.76-0.92) and for IPP an AUC of 0.88 (95% CI 0.80-0.97). CONCLUSION Detrusor thickness and intravesical prostatic protrusion have strong negative correlation with Qmax. These parameters could be an alternative to Qmax measurement if uroflowmetry is unavailable. LEVEL OF EVIDENCE Grade B.

Abstract
Introduction The aim of this article was to evaluate non-invasive tests, which were typically used in preoperative diagnosis of male patients with anterior urethral strictures in the assessment of the urethral resistance caused by urethral occlusion. Material and methods A total of 63 adult males with confirmed urethral stricture and aged below 55 years old were enrolled in the study. Data obtained from non-invasive tests such as uroflowmetry (UF), ultrasound examination (USG), and questionnaires such as from The International Prostatic Symptom Score (IPSS), and The Patient-Reported Outcome Measure for Urethral Stricture Surgery (USS-PROM) were analyzed. Results Among all analyzed non-invasive tests, bladder wall thickness (BWT) showed the highest correlation with the degree of urethral occlusion described as percentage of preserved urethral lumen (r = -0.70; p <0.0001). UF variables presented medium degree of correlation, with maximum flow rate (Qmax) as the best parameter (p = 0.45; p = 0.0005). Results from both questionnaires did not show any correlation with the severity of the urethral stricture. Multiple linear regression analysis showed that only BWT was an independent predictor in detection degree of urethral occlusion. Conclusions UF and USG seem to be useful additional diagnostic tools in assessment severity of urethral occlusion in men suffering from anterior urethral stricture. Among them, USG had the highest correlation with degree of urethral occlusion.

Abstract
BACKGROUND Multichannel urodynamics is the gold standard for the evaluation of lower urinary tract symptoms (LUTS). When performing studies to validate new adjuncts to urodynamic testing with control patients undergoing urodynamic investigation, there is difficulty in the interpretation of urodynamic results in the asymptomatic patient due to artifacts and the invasive nature of the procedure. The purpose of this investigation was to examine urodynamics in asymptomatic volunteers in order to better understand the role of control participants in urodynamic research studies. METHODS Asymptomatic volunteers with no LUTS were recruited to undergo standard urodynamic testing as a comparison group in a study evaluating novel urodynamic techniques. To be eligible, participants had to report no LUTS, score ≤1 on all symptom questions of the International Consultation on Incontinence Questionnaire Overactive Bladder Module (ICIq-OAB) survey, have no medical conditions or to undergo any medications that affect bladder function. The urodynamics was done according to ICS standards. All tracings were evaluated by an expert neuro-urologist. Data were analyzed categorically for the presence or absence of low compliance (<30 mL/cmH20), detrusor overactivity, bladder outlet obstruction (Bladder Outlet Obstruction Index [BOOI]>40), weak contractility (bladder contractility index [BCI]<100), straining to void, poorly sustained detrusor contraction, uncoordinated EMG activity, and intermittent flow. RESULTS A total of 24 participants completed the study including 10 men and 14 women. All participants had at least 1 urodynamic abnormality/artifact with an average of 4.43±1.28 abnormalities/participant. The most common abnormalities included uncoordinated electromyography (EMG) activity (87.50%), straining to void (79.17%), and intermittent flow (70.83%). There were no significant differences for sex, age, Body Mass Index. CONCLUSIONS This study demonstrated that healthy, asymptomatic volunteers have high rates of abnormal urodynamic findings, suggesting that asymptomatic participants are not the ideal controls in research studies that involve urodynamic testing.

Abstract
CONTEXT Urodynamic study (UDS) provides the most objective assessment of bladder outlet obstruction (BOO) but is impractical to be recommended routinely in outpatient services. Intravesical prostatic protrusion (IPP) had been described to obstruct urinary flow by creating an anatomical ball-valve effect, but there remains a lack of pooled evidence that can objectively correlate with BOO in benign prostatic hyperplasia. OBJECTIVE To update the current evidence on the predictive role of IPP in determining BOO and unsuccessful trial without catheter (TWOC). EVIDENCE ACQUISITION A comprehensive literature search was performed to identify studies that evaluated IPP in diagnosing UDS-determined BOO and TWOC. The search included the PubMed/MEDLINE, EMBASE, and Cochrane Library up to January 2021. An updated systemic review and meta-analysis was performed. EVIDENCE SYNTHESIS A total of 18 studies with 4128 patients were examined. Eleven studies with 1478 patients examined the role of IPP in UDS-determined BOO. The pooled area under the curve (AUC) was 0.83 (95% confidence interval [CI]: 0.79-0.86), and at a cut-off of >10 mm, the sensitivity (Sn) and specificity (Sp) were 0.71 (95% CI: 0.61-0.78) and 0.77 (95% CI: 0.68-0.84), respectively. The probability-modifying plot revealed positive and negative likelihood ratios of 3.34 (95% CI: 2.56-4.36) and 0.35 (95% CI: 0.26-0.45), respectively. Seven studies with 2650 patients examined IPP in predicting unsuccessful TWOC, with a pooled AUC of 0.74 (95% CI: 0.70-0.84), with Sn of 0.51 (95% CI: 0.43-0.60) and Sp of 0.79 (95% CI: 0.73-0.84) at an IPP cut-off of >10 mm. Five studies compared prostate volume (PV) and IPP and revealed a lower AUC of PV at 0.71 (95% CI: 0.67-0.75), which was an inferior parameter in diagnosing BOO (p < 0.001). CONCLUSIONS This systemic review provided evidence that IPP is a reliable clinical parameter that correlates strongly with underlying BOO and unsuccessful TWOC. PATIENT SUMMARY In this review, we comprehensively reviewed all the literature to date on evaluating the clinical utility of intravesical prostatic protrusion (IPP). We have demonstrated that IPP correlates strongly with urodynamic study (UDS)-determined bladder outlet obstruction and failure of trial without catheter (TWOC). Outpatient IPP measurement is a quick, inexpensive, and reproducible clinical parameter that can determine the severity of benign prostatic hyperplasia. The clinical role of IPP in predicting failure of TWOC selects patients who are best treated with aggressive surgical approaches rather than conservative medical therapies. More importantly, IPP can facilitate the discriminatory use of invasive UDS, reserved for patients with a strong suspicion of concomitant detrusor abnormalities.

Abstract
CONTEXT Female bladder outlet obstruction (fBOO) is a relatively uncommon condition compared with its male counterpart. Several criteria have been proposed to define fBOO, but the comparative diagnostic accuracy of these remains uncertain. OBJECTIVE To identify and compare different tests to diagnose fBOO through a systematic review process. EVIDENCE ACQUISITION A systematic review of the literature was performed according to the Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. The EMBASE/MEDLINE/Cochrane databases were searched up to August 4, 2020. Studies on women ≥18 yr of age with suspected bladder outlet obstruction (BOO) involving diagnostic tests were included. Pressure-flow studies or fluoroscopy was used as the reference standard where possible. Two reviewers independently screened all articles, searched reference lists of retrieved articles, and performed data extraction. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). EVIDENCE SYNTHESIS Overall, 28 nonrandomised studies involving 10 248 patients were included in the qualitative analysis. There was significant heterogeneity regarding the characteristics of women included in BOO cohorts (ie, mixed cohorts including both anatomical and functional BOO). Pressure-flow studies ± fluoroscopy was evaluated in 25 studies. Transperineal Doppler ultrasound was used to evaluate bladder neck dynamics in two studies. One study tested the efficacy of transvaginal ultrasound. The urodynamic definition of fBOO also varied amongst studies with different parameters and thresholds used, which precluded a meta-analysis. Three studies derived nomograms using the maximum flow rate (Qmax) and voiding detrusor pressure at Qmax. The sensitivity, specificity, and overall accuracy ranges were 54.6-92.5%, 64.6-93.9%, and 64.1-92.2%, respectively. CONCLUSIONS The available evidence on diagnostic tests for fBOO is limited and heterogeneous. Pressure-flow studies ± fluoroscopy remains the current standard for diagnosing fBOO. PATIENT SUMMARY Evidence on tests used to diagnose female bladder outlet obstruction was reviewed. The most common test used was pressure-flow studies ± fluoroscopy, which remains the current standard for diagnosing bladder outlet obstruction in women. TAKE HOME MESSAGE: The available evidence on diagnostic tests for female bladder outlet obstruction is limited and heterogeneous. The most common test used was video-urodynamics, which remains the current standard for diagnosing bladder outlet obstruction in women.

Abstract
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. Three-dimensional 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.

Analysis of radioactive implant migration in patients treated with iodine-125 seeds for permanent prostate brachytherapy with MRI-classified median lobe hyperplasia. J Contemp Brachytherapy 2021; 13:254-262.

Abstract
Purpose Prostate cancer with median lobe hyperplasia (MLH) is a relative contraindication for permanent prostate brachytherapy (PPB) because of an increased risk of post-implant dysuria and technical difficulties associated with achieving stability while implanting within the intravesical tissue. We examined treatment outcome, seed migration, and urination disorders after treatment in MLH patients in order to determine to what degree MLH implants could be stabilized. Material and methods Between March 2007 and December 2016, 32 patients had MLH identified radiologically on magnetic resonance imaging, and 193 patients did not have MLH (non-MLH). All patients were treated with loose seeds. In this study, seed migration was defined as a seed distant from the target (≥ 1.5 cm) and/or with no dosimetric contribution to the target. The MLH patients were divided into 2 MLH groups of mild (< 10 mm) and severe (≥ 10 mm) MLH by measuring the distance between the posterior transitional zone and the prostatic tissue protruding into the bladder. We retrospectively analyzed seed migration, dose-volume histograms (DVH), and genitourinary toxicity. Results MLH was classified as mild in 24 patients and severe in 8. Seed migration occurred in 61 (31.6%) of 193 non-MLH patients and 10 (31.5%) of 32 MLH patients. Implant seed migration and low-dose level of median lobe tended to be high in severe MLH cases. International Prostate Symptom Score (IPSS) peaked one month after implantation, but then resolved slowly and returned to around the pre-treatment level after one year. There were no severe complications. Conclusions MLH does not appear to be a strong contraindication for low-dose-rate brachytherapy. However, we found that the seed migration and degree of cold spots tended to be higher in severe MLH cases than in others; therefore, close attention when treating severe MLH cases must be paid.

Abstract
Objectives To identify non-invasive predictors of response to tamsulosin 0.4 mg in patients with benign prostatic obstruction (BPO). Methods Males ≥ 50 years of age with lower urinary tract symptoms (LUTS) suggestive of BPO for over three months were included in the study. We assessed change in the mean International Prostate Symptom Score (IPSS) and maximum flow rate (Qmax) after six weeks of medical therapy. Clinical and uroflowmetry parameters were compared between two groups of patients with >25% vs. <25% change in the IPSS after treatment. Pre- and post-treatment post-void residue (PVR), Qmax, and IPSS were compared by independent t-test, univariate/multivariate regression analysis. Results A total of 121 patients were included. At presentation, the mean prostate size was 35.7±12.2 grams and the mean IPSS was 16.3 ± 4.8. Improvement in the mean IPSS was 7.83, with more marked improvement in storage compared to voiding LUTS (5.26 vs. 2.57). Majority (58%) had a quality of life (QoL) score of 4-5 at presentation whereas after 6-weeks of medication (83.5%) had a QoL score of 0-2. Treatment failure was noted in 11 (9.1%) patients. IPSS was higher and Qmax was lower at the time of presentation in patients who had <25% improvement. However, the two groups were identical on the basis of demographic and other factors (BMI, age, prostate size, PVR). Conclusion Moderate LUTS secondary to BPO responds favourably to alpha-blocker (tamsulosin 0.4 mg) treatment. Uroflowmetry (UFM) parameters, that is, Qmax and IPSS are important factors in predicting short-term response to medical therapy.

Evaluation of Alpha 1 Adrenoceptor Antagonist Dose Increase Therapy: An Essential Strategy for Patients with Lower Urinary Tract Symptoms Associated with Benign Prostatic Hyperplasia. Curr Urol 2020; 14:113-121.

Abstract
Introduction There have been a number of reports on dose increase therapy (DI-T) with the alpha 1 adrenoceptor antagonists (α1-blockers) naftopidil and tamsulosin for lower urinary tract symptoms associated with benign prostatic hyperplasia. Methods and Results The reports on DI-T (naftopidil 75 mg/d, tamsulosin 0.4 mg/d) in non-responders to low-dose initial therapy (LI-T, naftopidil 50 mg/d, tamsulosin 0.2 mg/d) were summarized. In each study, a non-responder was defined as a patient without sufficient improvements on the International Prostate Symptom Score (IPSS), IPSS Quality of Life, maximum flow rate of urine, or treatment satisfaction. These reports showed that 22.4-76.1% of patients were non-responders to LI-T, indicating that a novel treatment strategy for such patients is important. Moreover, 22.5-90.0% of non-responders to LI-T showed a response to DI-T, which achieved the same level of efficacy as low-dose maintenance therapy. Specifically, the improvements of the IPSS voiding symptom sub-score and maximum flow rate of urine were superior. The predictive factors for non-response to α1-blockers LI-T were insufficient improvement of subjective symptoms and objective findings during LI-T. These patients require high-dose initial therapy or DI-T at an early stage, since adverse events associated with naftopidil and tamsulosin do not show a dose-response relationship. Conclusions DI-T with α1-blockers has high potential as an essential treatment strategy for lower urinary tract symptoms associated with benign prostatic hyperplasia.

Abstract
Detrusor underactivity (DU) is a common bladder dysfunction that causes lower urinary tract symptoms (LUTS) in both men and women. Currently DU can only be diagnosed by an invasive urodynamic test. Underactive bladder (UAB) is the symptom-based correlate of DU, as is the case with overactive bladder (OAB) and detrusor overactivity (DO). The International Continence Society (ICS) consensus group has recently proposed a working definition of UAB as a symptom syndrome suggestive of DU. However, a symptom complex of UAB is shared by LUTS attributable to bladder outlet obstruction (BOO). Thus, UAB is not specific for DU, leading to difficulties in determining a therapeutic target (DU or BOO) in the initial management of UAB. Under these circumstances, a consensus group was formed under the auspices of the Japanese Continence Society (JCS) and diagnostic criteria were produced to potentially identify patients likely to have DU, without a pressure/flow study-based diagnosis. Certain symptoms and several noninvasive test parameters have been reported as clinical predictors of DU, and were suggested to discriminate DU from BOO. Of these predictive factors, the more commonly used parameters were used to develop clinical diagnostic criteria for DU. This article presents the clinical diagnostic criteria for DU proposed by the JCS consensus group and aims to summarize the background discussion by the group.

Abstract
Lower urinary tract symptoms (LUTS) are common complaints in the adult male population and have a negative affect in the quality of life and represent an economic burden for the healthcare system worldwide. The International Prostatism Symptom Score (IPSS) is a validated tool for assessing these symptoms, but patients with low literacy may have difficulties comprehending and completing it accurately. The Urgency, Weak Stream, Incomplete Emptying, and Nocturia (UWIN) questionnaire was developed as a shorter tool in the assessment of LUTS to improve accuracy and minimize error. This study aimed at performing cross-cultural adaptation to Brazilian Portuguese and validation of UWIN questionnaire for patients with LUTS. The cross-cultural adaptation followed the steps of conceptual, item, semantic, operational, and pre-test equivalence to obtain the UWIN-Br version. The IPSS (gold standard) and UWIN-Br were coadministered, and information regarding the uroflowmetry examination was also recorded. We evaluated 306 men, median age 59 [52-66] years. There was a positive correlation r = 0.804 (p < 0.001) between the total IPSS score and the total UWIN-Br score, as well as the quality of life question (r = 0.761) (p < 0.001). The Bland-Altman plot showed good agreement between. Also, we observed that the maximum flow values decreased with the severity of the LUTS. UWIN-Br demonstrated excellent diagnostic accuracy in detecting the most severe cases. The area under the ROC curve was 89% [81–97%] 95% CI. 280 (91.5%) subjects completed the questionnaires without help, while 26 (8.5%) did so through an interview. The response time was 1.2 [1.0–1.5] min for UWIN-Br and 2.8 [2.2–3.4] min for IPSS (p < 0.001). UWIN-Br presents satisfactory and similar psychometric properties to the IPSS in the evaluation of LUTS and quality of life and is suitable for use in both clinical practice and research in our country.

Abstract
AIMS To assess the state of technologies for urodynamics that are less invasive than standard cystometry and pressure-flow studies and to suggest areas needing research to improve this. METHODS A summary of a Think Tank debate held at the 2019 meeting of the International Consultation on Incontinence Research Society is provided, with subsequent analysis by the authors. Less-invasive techniques were summarized, classified by method, and possible developments considered. Discussions and recommendations were summarized by the co-chairs and edited into the form of this paper by all authors. RESULTS There is a full spectrum of technologies available for less-invasive assessment, ranging from simple uroflowmetry through imaging techniques to emerging complex technologies. Less-invasive diagnostics will not necessarily need to replace diagnosis by, or even provide the same level of diagnostic accuracy as, invasive urodynamics. Rather than aiming for a technique that is merely less invasive, the priority is to develop methods that are either as accurate as current invasive methods, or spare patients from the necessity of invasive methods by improving early triaging. CONCLUSIONS Technologies offering less-invasive urodynamic measurement of specific elements of function can be potentially beneficial. Less-invasive techniques may sometimes be useful as an adjunct to invasive urodynamics. The potential for current less-invasive tests to completely replace invasive urodynamic testing is considered, however, to be low. Less-invasive techniques must, therefore, be tested as screening/triaging tools, with the aim to spare some patients from invasive urodynamics early in the treatment pathway.

Flow resistive forces index (QRF): Development and clinical applicability assessment of a novel measure of bladder outlet resistance, aiming to enhance the diagnostic performance of uroflowmetry. Low Urin Tract Symptoms 2020; 12:190-197.

Abstract
BACKGROUND Currently, the diagnostic ability of uroflowmetry, the most widely used urodynamic test available for initial assessment of patients with lower urinary tract symptoms (LUTS), is considered limited by its inability to accurately discriminate between the underlying mechanisms of this condition. To improve the diagnostic accuracy of uroflow, we developed a mathematical formula that calculates the flow resistive forces index (QRF), a novel measure of bladder outflow/urethral resistance, and assessed its clinical applicability compared to the maximum flow rate (Qmax ). MATERIALS AND METHODS A cross-sectional observational study was conducted in a cohort of 61 adult men presenting with voiding dysfunction symptoms, who all underwent free uroflowmetry followed by pressure flow study. The development of the mathematical formula which contains five key uroflowmetry variables (voided volume, flow time, Qmax , average flow rate, and peak flow time) was based on the assumption that urine volume momentum changes during voiding, the concept of diphasic uroflow pattern (acceleration/deceleration), and the urethral resistance factor (URA) equation. Study subjects were classified either as obstructed or nonobstructed according to established urodynamic criteria (linearized passive urethral resistance relation, LinPURR; Abrams-Griffiths number, AGN [also called bladder outlet obstruction index, BOOI]; and URA). Univariate linear correlations, binary logistic regression model, and receiver operating characteristic (ROC) curve statistical analysis were employed (SPSS-22, MedCalc, GraphPad [P < .05]). RESULTS Outflow obstruction was diagnosed in 50.8% (1 in 2) patients. Univariate analysis, and bivariate linear correlation, binary logistic regression, and ROC curve analyses showed that the QRF was a strong independent predictor of bladder outlet/outflow obstruction (BOO), significantly outperforming Qmax . CONCLUSIONS QRF index accurately predicts BOO, significantly outperforming the currently widely used bladder outlet obstruction estimator Qmax . Despite potential study limitations (mainly small cohort size and lack of control group), we anticipate that with further study and proper clinical validation, QRF could become a valuable complement to uroflowmetry.

Abstract
PURPOSE To evaluate the association of intravesical prostatic protrusion (IPP) and overactive bladder (OAB) in male patients with lower urinary tract symptoms (LUTS). IPP has been suggested to correlate with storage symptoms in addition to bladder outlet obstruction. METHODS This was an open-labeled, single-center, prospective study involving 128 men older than 40 years presenting with LUTS. We analyzed the relationship of IPP with age, prostate volume, uroflowmetry, post-void residual urine volume (PVR), International Prostate Symptom Score (IPSS), urgency severity scale (USS), and OAB symptom score (OABSS). The patients with an urgency score of ≥ 2 (OABSS question 2) and sum score of ≥ 3 were considered to have OAB. IPP was measured in the mid-sagittal section using transrectal ultrasound. The degree of IPP was classified as grade 1 (≤ 5 mm), grade 2 (> 5-10 mm), and grade 3 (> 10 mm). RESULTS The mean age of the patients was 64.9 ± 9.2 years, and 101 patients were diagnosed with OAB (79%). Mean IPPs were 2.4 ± 1.4 mm (grade 1, n = 77), 7.6 ± 1.4 mm (grade 2, n = 27), and 14.8 ± 4.4 mm (grade 3, n = 24). IPP was positively correlated with age, prostate size, PSA, PVR, and OABSS nocturia subscore, but not correlated with the presence or severity of OAB. Areas under the receiver-operating characteristic (ROC) curves for the diagnosis of OAB were 0.807 and 0.604 for IPSS-storage subscore and IPP, respectively. CONCLUSION IPP is not a good predictor of OAB in men presenting with LUTS. However, grade 3 IPP indicates higher frequency of nocturia.

Abstract
PURPOSE To identify urodynamic factors associated with the mechanical stop test and immediate spontaneous voiding following transurethral resection of prostate (TURP). METHODS We identified 90 men who underwent TURP over a 12-month period. Forty-three (mean age 68 years) underwent urodynamic evaluation prior to TURP. Isovolumetric detrusor contractile pressure (Piso) was obtained using the mechanical stop test during the voiding phase, and used to calculate detrusor contractile reserve (Pres = Piso - Pdet@Qmax). Primary outcome was spontaneous voiding after TURP. RESULTS Preoperative catheter-free spontaneous voiding was present in 63% of men (27/43) with a urodynamic (mean ± SD): Qmax 6.2 ± 2.7 mL/s, Pdet@Qmax 102 ± 47 cmH2O, Piso 124 ± 49 cmH2O, Pres 22 ± 16 cmH2O, bladder outlet obstruction index (BOOI) 90 ± 49, and bladder contractility index (BCI) 132 ± 44. The remaining 16 catheter-dependent men demonstrated a urodynamic (mean ± SD): Qmax 3.6 ± 3.3 mL/s, Pdet@Qmax 87 ± 38 cmH2O, Piso 99 ± 51 cmH2O, Pres 10 ± 18 cmH2O, BOOI 82 ± 36, and BCI 106 ± 48. Following TURP, 67% of men voided spontaneously with their first void trial, and in receiver operator analysis of urodynamic measures (Pdet@Qmax, Piso, Pres, BOOI and BCI), only Pres was significantly associated with immediate spontaneous voiding after TURP (threshold Pres ≥ 9 cmH2O, AUC = 0.681, p = 0.035). CONCLUSIONS In men who underwent TURP, a Pres ≥ 9 cmH2O was associated with immediate spontaneous voiding and may be easily incorporated into the postoperative pathway.

Abstract
Objective To analyze the association between neutrophil‐to‐lymphocyte ratio (NLR) and intravesical prostatic protrusion (IPP) in men with benign prostatic hyperplasia. Methods Two hundred and fifty men aged >50 years who presented with lower urinary tract symptoms at our institution between 2014 and 2018 were analyzed. Pearson's method was used for analysis of the correlation between NLR and IPP. Multivariate logistic regression analysis was used to identify predictors of IPP. Further analysis according to total prostate volume (TPV) was performed. Results The NLR correlated positively with IPP (Pearson's r = 0.459, P < 0.001) and was an independent predictor of IPP ≥10 mm (odds ratio, 2.95; 95% confidence interval, 1.59–5.47; P = 0.0006). Among the 142 men with prostates <40 cm3, mean NLR was 2.50 ± 0.71 in those with IPP ≥10 mm and 1.71 ± 0.57 in those with IPP < 10 mm (P < 0.001). The NLR differed significantly between those with a prostate <40 cm3 and IPP ≥10 mm and those with a larger prostate and IPP < 10 mm (2.50 ± 0.71 vs 2.07 ± 0.77, respectively; P = 0.020). Conclusions NLR can be used as a surrogate marker for presence of IPP. Its clinical value would be especially important in men with a small prostate gland but high IPP. The NLR seemed to be more strongly correlated with IPP than with TPV.

Abstract
OBJECTIVE To develop a questionnaire for the differential diagnosis of detrusor underactivity (DUA) and bladder outlet obstruction (BOO) without performing invasive pressure flow studies. STUDY DESIGN AND METHODS Symptoms of men with DUA were analyzed and compared with those of men with BOO using eight questions from the developing questionnaire. Patients with DUA have a bladder contractility index (PdetQmax+5xQmax) less than 100, whereas those with BOO have a BOO index (PdetQmax-2xQmax) greater than 40 in urodynamic studies (UDS). Men with detrusor overactivity in UDS and neurogenic issues were excluded from the analysis. One urologist reviewed patients' medical records, and responded to eight questions without using information from UDS. Scores in the developing questionnaire were then compared to make a differential diagnosis between DUA and BOO. RESULTS Overall, 318 men who underwent UDS were included. Symptoms were compared in patients diagnosed with DUA without BOO (n = 165) and BOO without DUA (n = 153). Questions 1, 2, 4, 5, 6, and 7 were significantly different between groups. The sensitivity and specificity of the questionnaire were 95.8% and 95.4%, respectively, for predicting DUA in patients with scores greater than 45 points (cutoff value). CONCLUSIONS Men with DUA and BOO may be distinguished using a developing questionnaire without invasive evaluation. Men with scores greater than 45 points would be expected to have DUA but not BOO.

Abstract
PURPOSE OF REVIEW Lower urinary tract symptoms (LUTS) is a common constellation of symptoms that affect the aging male population with an astonishing prevalence. New technology and new uses of established technology are being used to help further evaluate LUTS in the male population and help guide treatment options. This review focuses on the developments and future directions in diagnostic modalities for evaluation of male LUTS, focusing on evaluation of both the filling and voiding phases of micturition. RECENT FINDINGS New techniques in evaluating the voiding phase include penile cuff test, external pressure sensing condom catheter, ultrasound measurement of detrusor wall thickness, ultrasound measurement of intravesical prostatic protrusion, doppler ultrasound and NIRS technology. Evaluation of the filling phase is still undergoing much development and requires additional validation studies. The techniques undergoing evaluation include sensation meters during UDS, assessing bladder micromotion and wall rhythm, assessing detrusor wall biomechanics, ultrasound measurement of detrusor wall thickness, pelvic doppler ultrasound, as well as functional brain imaging including fNIRS and fMRI. SUMMARY The development of novel, non-invasive, diagnostic tools have the potential for better evaluation of LUTS with earlier and enhanced treatments. This will likely improve the quality of life for men with LUTS.

Abstract
Objective: To investigate the safety and efficacy of the combination of suprapubic prostatectomy with transurethral resection of the prostate (TURP) for the treatment of large volume benign prostatic hyperplasia (BPH). Methods: We retrospectively analyzed the clinical data of two methods of treatment with 60 cases of a large volume BPH (>100 g) from January 2011 to 2017; the methods were suprapubic prostatectomy and suprapubic prostatectomy combination with TURP, in which the single open group comprised 30 cases, treated using the former method, and the combined open group comprised the other 30 cases, treated using the latter method. In the combined open group, the residual prostate gland was removed by TURP. We compared both the groups of patients using age, prostate volume, international prostate symptom score (IPSS), prostate-specific antigen (PSA), maximum flow rate, residual urine, operation time, hospitalization time, postoperative washing time, blood transfusion rate, and decreased amount of intraoperative hemoglobin in operation, and compared the preoperative and postoperative IPSS, maximum flow rate, and residual urine volume. Results: There was no significant difference between the two groups in age, prostate volume, IPSS, PSA, maximum flow rate, residual urine, and other clinical data ( P > 0.05); the single group operation time, postoperative bladder irrigation time, hospitalization time, blood transfusion rate, and decreased amount of intraoperative hemoglobin were significantly greater in the single open group than in the combined open group, and statistically significant differences were observed between both the groups ( P < 0.05). Postoperative voiding function improved significantly compared with the preoperative, and a statistically significant difference was observed ( P < 0.05). Conclusion: The combination of suprapubic prostatectomy with TURP is an effective and a safe surgical method for the treatment of patients with large volume BPH. It is certainly worthy of clinical application.

Abstract
Urodynamic studies assess the function of the bladder and bladder outlet. They are often useful in the assessment and diagnosis of patients presenting with lower urinary tract symptoms (LUTS). The evidence regarding the value and risks of invasive urodynamics remains insufficient. However, men with LUTS who are assessed by invasive urodynamics are more likely to have their management changed and less likely to undergo surgery. This review discusses the role of urodynamic diagnosis and application in the diagnosis and treatment of male LUTS.

Abstract
Urodynamics can distinguish bladder outlet obstruction from detrusor underactivity. Clear identification of the mechanism of a man's voiding symptoms can help give the best chance of good outcome from surgery. Publication of results from the UPSTREAM study will help in establishing the exact place for urodynamic testing in male lower urinary tract symptoms.

Abstract
Lower urinary tract symptoms (LUTS) are common in males over the age of 40 years old and are likely to increase with an aging population. Currently urodynamic studies are the gold standard to determine the aetiology of voiding dysfunction and LUTS. However, due to its invasive nature, a great number of non-invasive ultrasound based investigations have been developed to assess patients with symptomatic LUTS. The clinical application of non-invasive tests could potentially stratify patients who would require more invasive investigations and allow more precise patient directed treatment. A PubMed literature review was performed and we will discuss the non-invasive investigations that have been developed thus far, focusing on bladder wall and detrusor wall thickness (BWT & DWT), ultrasound estimated bladder weight (UEBW) and intravesical prostatic protrusion (IPP).

Abstract
OBJECTIVE The aim of this study was to evaluate the effects of robot-assisted radical prostatectomy (RARP) on uroflowmetry (UF) parameters among men with baseline peak flow rates (PFR) <10 mL/s. METHODS A single-surgeon RARP database of 1082 men who underwent prospective UF testing was analyzed. Men filled out International Prostate Symptom Score questionnaires and underwent uroflowmetry and post-void bladder ultrasound before surgery and at each follow-up visit. Patients were divided into 2 groups based on preoperative PFR: those with PFR <10 mL/s (n = 158) and those with PFR ≥10 mL/s (n = 924). Univariate and multivariate regression models tested the association of preoperative characteristics in predicting postoperative PFR improvement. Within the PFR <10 mL/s group, preoperative variables were analyzed to predict pathologic outcomes. RESULTS Three months after RARP, men with baseline PFR <10 mL/s had a 3-fold improvement in PFR (from mean of 7.0 to 24.2 mL/s), whereas in men with PFR ≥10 mL/s there was a 50% improvement (from mean of 19.7 to 28.9 mL/s; P < .001). Improvement in PFR remained stable for >5 years, but mean postoperative PFR was 20% lower in men with baseline PFR <10 mL/s. Preoperative prostate-specific antigen (odds ratio [OR] 0.75; 95% confidence interval [CI] 0.59-0.95) and PFR (OR 0.52; 95% CI 0.34-0.80) were independent predictors of the percentage improvement in men with baseline PFR <10 mL/s. Preoperative PFR ≤7 mL/s was an independent predictor of Gleason score ≥8 (P = .016), seminal vesicle invasion (P = .010), and lymph node invasion (0.029). CONCLUSIONS After RARP, PFR improved significantly, with the improvement persisting over long-term follow-up. However, men with baseline PFR <10 mL/s had a 20% lower postoperative PFR over 5 years, suggesting permanent damage to the bladder and the need for early treatment to maintain bladder health. There appears to be an association between baseline PFR ≤7 mL/s and adverse pathologic features.
