Real-world experience of water vapour therapy (Rezum) in patients with benign prostatic enlargement: a retrospective single-center study. Prostate Cancer Prostatic Dis 2024:10.1038/s41391-024-00836-w. [PMID: 38658736 DOI: 10.1038/s41391-024-00836-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/11/2024] [Accepted: 04/12/2024] [Indexed: 04/26/2024]
Abstract
BACKGROUND Water vapor thermal therapy (Rezum) is a minimally invasive treatment for benign prostatic enlargement (BPE). Studies reporting urodynamic results regarding the procedure are rare. Our study aimed to assess the effectiveness of Rezum on urinary outcome parameters in a consecutive series of patients and compare urodynamic data before and after treatment. METHODS We retrospectively evaluated all the patients treated with Rezum between 07/2017 and 12/2023 at our institution. Patients who had more than one Rezum intervention, those who were unable to void (i.e., catheter-dependent patients), and those with insufficient data were excluded from the data analysis. Descriptive outcomes, such as symptom scores (IPSS, IPSS-QoL), peak flow in uroflowmetry (Qmax), post-micturition residual urine volume (PVR), and prostate volume (PVol), were analyzed. If available, preoperative and postoperative urodynamic results were evaluated. RESULTS In total, 250 Rezum procedures were performed during the observational period. After applying the exclusion criteria, the data from 193 patients were included in the analysis. Patients achieved significant symptom relief as measured using the IPSS (46% reduction) and IPSS-QoL scores (41% reduction). Qmax improved by 4.8 ml/s, as the mean PVR significantly decreased by 50%. PVol and PSA values decreased by 30% and 27.5%, respectively. In 19/193 patients with a urodynamic evaluation, pre- and postoperative data analysis showed a significant reduction in the bladder outlet obstruction index (BOOI) by approximately 70%. CONCLUSIONS Rezum is effective and can improve urinary symptoms. In appropriate patients, Rezum can significantly reduce the bladder outlet obstruction (BOO).

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.

Abstract
Underactive bladder (UAB) is a prevalent but under-researched lower urinary tract symptom that typically occurs alongside detrusor underactivity (DU). Unlike UAB, DU is a urodynamic diagnosis which the International Continence Society (ICS) defines as "a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span". Despite the widespread prevalence of UAB/DU, there are significant gaps in our understanding of its pathophysiological mechanisms, diagnosis, and treatment compared with overactive bladder (OAB) and detrusor overactivity (DO). These gaps are such that clinicians regard UAB/DU as an incurable condition. In recent years, the understanding of UAB has increased. The definition of UAB has been clarified, and the diagnostic criteria for DU have been considered more comprehensively. Meanwhile, a number of non-invasive diagnostic methods have also been reported. Clinical trials involving novel drugs, electrical stimulation, and stem cell therapy have shown promising results. Therefore, this review summarizes recent reports on UAB and DU and highlights the latest advances in their diagnosis and treatment.

Abstract
Abstract
Background
Benign prostatic hyperplasia (BPH) and the use of CCBs are common in older persons, and are also associated with lower urinary tract symptoms (LUTS). This review summarised and synthesised relevant information and recent advances to improve clinical knowledge on the role of CCBs in LUTS, BPH symptoms and health-related quality of life.
Main body of the abstract
A search of databases of PubMed, Web of science, Hinari, and Google scholar was performed using several keywords. Relevant studies were also extracted from references of identified studies. Selected studies were assessed for content related to CCBs, BPH and LUTS, and the most relevant reports were included. The inhibition of calcium channels by CCBs interferes with influx of extracellular Ca2+ into the detrusor muscle, which interferes with bladder contraction and relaxation. Hence, CCBs are associated with precipitation or aggravation of urinary storage and voiding symptoms, which are also common symptoms of BPH. This suggests a potential aggravation of BPH symptoms with the use of CCBs.
Short conclusion
Persons at high risk of LUTS such as in BPH, may benefit from other classes of antihypertensive drugs. Therefore, it is essential to identify persons with BPH prior to commencement of therapy with CCBs. Patients on CCBs should be routinely reviewed for any potential precipitation or aggravation of LUTS. Patients should also be counselled to notify their healthcare provider of unusual urinary symptoms during CCB use. This will facilitate enhanced quality of life in patients with BPH.

Abstract
Detrusor underactivity (DU) and bladder outlet obstruction (BOO) are both common troublesome causes of lower urinary tract symptoms (LUTS) and often impact on quality of life simultaneously in men. This article aims to focus on DU with BOO in male patients. METHODS Original articles concerning DU with BOO were identified through literature research from PubMed and EMBASE database. We selected 38 articles in our review, including those concerning pathophysiology, evaluation, treatment and predictors for a successful BOO surgery for DU. RESULTS DU from BOO can result from several pathophysiological mechanisms. Although urodynamic study (UDS) is considered as a precise method to diagnose DU and BOO, there are some previous studies which proposed a non-invasive method to identify DU related to BOO. The treatment goal of DU is restoring bladder contractility using medication or surgery. Releasing outlet obstruction and resistance is the main strategy to restore bladder contractility when medication to directly increase bladder contractility has had limited efficacy. CONCLUSIONS DU from BOO is poorly understood and is largely under-researched. The etiology and pathophysiology still need to be evaluated. Effective and safe medication to restore bladder contractility is also lacking. It remains valuable to perform further research to reveal the unknown aspects of DU.

Muscarinic-3-receptor positive allosteric modulator ASP8302 in patients with underactive bladder. A randomized controlled trial. Neurourol Urodyn 2022; 41:1139-1148. [PMID: 35419807 DOI: 10.1002/nau.24931] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/07/2022] [Accepted: 03/14/2022] [Indexed: 11/07/2022]
Abstract
AIM The aim of this study is to evaluate safety and efficacy of ASP8302, a novel positive allosteric modulator for the muscarinic M3 receptor (M3-PAM), in patients with underactive bladder (UAB). METHODS A randomized, double-blind, placebo-controlled multicenter study was performed in adult male/female subjects with UAB, defined as incomplete bladder emptying (postvoid residual volume [PVR] > 100 ml) without significant bladder outlet obstruction and/or overactive bladder. Subjects were randomized (1:1) to receive 4-week oral once-daily administration of 100 mg ASP8302 or matching placebo. Primary endpoint was a change from baseline in PVR measured by catheterization after standardized bladder filling (PVRC2 ). Other endpoints included PVR and bladder voiding efficiency (BVE) measured in various ways, uroflowmetry, bladder diary, and questionnaires. Pressure-flow studies were performed in a subgroup. RESULTS One hundred and thirty-five patients were randomized (ASP8302 group: 65 patients, placebo group: 70 patients). The median change in PVRC2 was -40.0 ml (ASP8302) versus -35.0 ml (placebo) and the difference between groups was -5.0 ml (p = 0.960). In males, functional and symptomatic outcomes improved, for example, maximum urine flow rate (Qmax ) and detrusor pressure at Qmax (Pdet.Qmax ) increased (mean difference in change ASP8302 vs. placebo: 3.8 ml/s, p = 0.031 and 12.7 cm H2 O, p = 0.034, respectively). Urinary incontinence episodes/24 h decreased in males with preexisting incontinence (mean difference: -0.35; p = 0.028). The incidence of adverse events was similar between study groups (ASP8302: 33.3%, placebo: 31.4%). In the included subjects, both baseline urine flow and bladder voiding pressure was low. Compared with PVR, simultaneous BVE measurements were more consistent between various methods (spontaneous vs. standardized bladder filling, catheterization vs. ultrasound [US]). CONCLUSIONS ASP8302 was safe and well tolerated in patients with UAB identified by nonurodynamic clinical criteria, but it did not show efficacy in the primary endpoint. However, in males it showed improvement of symptoms and functional parameters. BVE (using US) is a more optimal outcome measure than PVR in UAB.

Abstract
Introdução No desenvolvimento da terminologia do trato urinário inferior, devido à sua crescente complexidade, a terminologia para os sintomas e a disfunção do trato urinário inferior masculino e assoalho pélvico precisa ser atualizada, utilizando abordagem específica masculina e por meio de um relatório de consenso clinicamente embasado. Métodos Este relatório combina a contribuição de membros do Standardisation Committee da International Continence Society em um Grupo de Trabalho com especialistas reconhecidos no campo, assistido por muitos julgadores externos. Categorias clínicas centrais apropriadas e uma subclassificação foram desenvolvidas para fornecer uma codificação numérica para cada definição. Um extenso processo de 22 rodadas de revisão interna e externa foi desenvolvido para examinar exaustivamente cada definição, com tomada de decisão por opinião coletiva (consenso). Resultados Um relatório de terminologia para os sintomas e a disfunção do trato urinário inferior e do assoalho pélvico foi desenvolvido, abrangendo cerca de 390 definições/descritores separados. É clinicamente embasado nos diagnósticos mais comuns definidos. A clareza e a facilidade de uso foram os principais objetivos para torná-lo interpretável por profissionais e estagiários em todos os diferentes grupos de especialidades envolvidos na disfunção do trato urinário inferior e do assoalho pélvico masculino. Imagens específicas para homens (ultrassonografia, radiologia, tomografia computadorizada e ressonância magnética) foram um adicional importante, enquanto figuras apropriadas foram incluídas para complementar e ajudar a esclarecer o texto. Conclusões Um relatório de terminologia com base em consenso para sintomas e disfunção do trato urinário inferior e do assoalho pélvico masculino foi produzido visando ser um auxílio significativo para a prática clínica e um estímulo para a pesquisa.

Abstract
INTRODUCTION The objective of the study was to compare the evolution of male patients with neurogenic detrusor underactivity (NDU) versus non-neurogenic DU (NNDU) and to establish risk factors to predict the need for clean intermittent catheterization (CIC) during the follow-up period. MATERIAL AND METHODS Longitudinal, descriptive study of a cohort of patients diagnosed with DU, and 2,496 urodynamic studies (2008-2018) were reviewed. Patients with DU (ICS 2002 and/or Bladder contraction index (< 100)) without treatment were included. Patients with CIC or interventional treatment were excluded. Follow-up included flowmetry every six months. CIC was indicated in cases of high residual volume (PVR) > 200 mL or voiding efficiency (VE)<50%. The need for CIC during follow-up or the appearance of complications (urinary tract infections (UTI), bladder lithiasis) were compared. RESULTS DU was found in 172 (6.89%) men. Neurological causes were observed in 106 (61,6%) cases. Finally, 62 patients were included with a mean follow-up of 4.9 years (+/- 2.6). Of these patients, 33 (53%) presented NDU and 29 (47%) NNDU. Six patients with NDU needed CIC versus none with NNDU (p = 0.04). Patients requiring CIC had higher PVR (p = 0.009) and lower VE (p = 0.017)), and there were also differences in terms of time until the need for CIC (log Rank: 0.009), which was 15.1 months [4-38]. In the multivariate analysis, none of the variables showed to be predictive of the need for CIC. CONCLUSIONS The most common cause of DU is neurologic injury. Patients with NDU remain stable without requiring CIC. We have not detected any risk factors that identify patients at risk of needing CIC.

Abstract
Herein we describe four clinical scenarios. For the standard patient (prostate volume 30-80 ml, life expectancy >10 years) transurethral resection of the prostate (TURP) remains the standard of care, while endoscopic enucleation is a valuable alternative. Patients with a relevant middle lobe profit most from TURP, endourological enucleation procedures, or laser vaporization. In the case of the absence or a moderate-sized middle lobe and the absence of severe bladder outlet obstruction (BOO), minimally invasive procedures such as Rezūm®, UroLift® or prostate artery embolization (PAE) can be offered. Patients have to be informed that long-term data on this specific indication are lacking. Particularly younger men requiring BPH surgery are interested in preserving ejaculatory function. In the presence of severe BOO, ejaculatory-protective TURP or endoscopic enucleation by preserving the pericollicular region or aquablation are the methods of choice providing an antegrade ejaculation in 60-90% of cases. Rezūm®, AquaBeam®, and UroLift® enable preservation of ejaculation in almost 100%; data on PAE with this respect are more controversial. For patients with a small prostate and significant post void residual, a thorough preoperative work-up, including urodynamics and bladder/detrusor wall thickness measurement, is of great importance. Desobstructive surgery provides satisfactory short- and midterm outcome, yet the long-term outcome is disappointing and remains to be determined in greater detail. The broad spectrum of therapeutic options enables today an individualized minimally invasive or surgical management of BPH considering patient wishes, anatomical factors or urodynamic factors. The time of a "one therapy fits all" strategy is definitely history.

Abstract
AIMS The aim of the study was to evaluate the transurethral resection of the prostate (TURP) outcomes of unobstructed patients with detrusor underactivity (DUA), comparing the surgical results between obstructed and unobstructed males with concomitant DUA, at midterm follow-up. METHODS This was an observational, prospective, comparative, nonrandomized study. Candidates to TURP underwent preoperative urodynamics (UD), with a diagnosis of DUA, were divided in two cohorts: Group A unobstructed men, group B males with bladder outlet obstruction (BOO). Males were evaluated yearly with uroflowmetry (UF), post-void residual (PVR), and bladder voiding efficiency (BVE), International Prostate Symptom Score (IPSS) questionnaire, visual analogic scale (VAS) for subjective assessment of the quality of life. The degree of the variation of maximum flow rate (Qmax), PVR, BVE, IPSS, VAS between baseline and follow-up (Δ) was evaluated. RESULTS Patients in group A were 28 and in group B 23. Overall patient's mean ± SD age was 63.37 ± 12.41 years. Preoperative urodynamics characteristics: mean bladder contractility index (BCI) of 61.15 and 76.25 in group A and B, respectively; mean bladder outlet obstruction index (BOOI) of 17.25 and 50.15 in group A and group B, respectively. After surgery, overall patient group, group A, and group B showed a statistical improvement in IPSS score (P < .0001), Qmax (P < .0001), PVR (P < .0008), BVE (P < .03) and VAS (P < .0001). CONCLUSIONS BOO had an important impact on the degree of improvement of Qmax and PVR/BVE, while had a poor influence on lower urinary tract symptoms amelioration. The most relevant outcomes were found when BOO was associated with DUA, which was not a contraindication to surgery.

Abstract
OBJECTIVES Post-void residual urine volume (PVR) and bladder voiding efficiency (BVE) are widely used as clinical parameters to evaluate patients with voiding dysfunction. The present study was conducted to assess the variability of PVR and BVE determinations in patients with underactive bladder (UAB). In addition, we focused on the bladder volume prior to voiding (BVvoid ) that may influence PVR and BVE, and investigated a correlation between PVR and BVvoid , and between BVE and BVvoid . METHODS Ten patients with a symptom complex of UAB, who had PVR of 50 mL or greater, were admitted to hospital during a 24-hour period for the measurement of voided volume (VV) and PVR. PVR was measured by transabdominal ultrasonography. BVE was expressed by a fraction (%) of bladder volume evacuated ([VV/BVvoid ] × 100). RESULTS Ten patients, five men (mean age of 65.0 years) and five women (mean age of 70.2 years), participated in this study. Regardless of gender, there was a large variation in repeated measurements of PVR in an individual patient. PVR increased with an increase in BVvoid , and there was a significant linear relationship between PVR and BVvoid . BVE was approximately constant after every voiding in each patient, and there was no significant linear relationship between BVE and BVvoid . CONCLUSIONS Measurement of PVR was unreliable because of wide variation in the same individual. The variation of BVE was much smaller than PVR. BVE would be a reliable parameter with good reproducibility for the assessment of emptying function.

Abstract
Background Urothelial cells release ATP into the urine in response to bladder stretch. Urinary ATP concentration in benign prostatic hyperplasia (BPH) patients was higher compared with asymptomatic controls. In this study, we aimed to explore the possibility that the urinary ATP level could be a non-invasive biomarker for bladder outlet obstruction (BOO) and its severity in BPH patients. Methods We included 117 BPH patients who underwent urodynamic studies and 109 asymptomatic controls. Urine samples at normal desire (from patients and controls), instilled fluids at maximum cystometric capacity (capacity fluid), and voided fluids during a pressure-flow study (only from patients) were collected. The ATP concentration in collected samples was measured using a luciferin-luciferase bioluminescence assay and normalized to urine creatinine (ATP/Cr). The degree of BOO was quantified using the BOO index (BOOI). Correlation between urodynamic parameters and urinary ATP concentration was analyzed in BPH patients. Results Urinary ATP concentration of BPH patients was significantly higher compared with controls (P<0.001). For BPH patients, a significant positive correlation was found between urinary ATP concentration and BOOI (P<0.0001). Although BPH patients with detrusor overactivity or a history of acute urinary retention had increased urinary ATP, a significant positive correlation between ATP and BOOI was also observed in these patients. When BOOI >40 was set as a cutoff point to differentiate BOO from non-BOO patients, the area under the receiver operating characteristic (ROC) curve was 0.77 (P<0.001). Conclusions BPH patients with BOO released higher amounts of ATP into the urine. Urinary ATP can be used as a non-invasive biomarker of BOO, and its level may also have a predictive value for the degree of obstruction.

Abstract
INTRODUCTION Widely accepted consensus terminology and calculations of detrusor contractility in females do not exist but may be useful. We report the output of a proposal session at the International Consultation on Incontinence Research Society meeting 2019, addressing the title topic. METHODS Three formal presentations and a lively discussion addressed several questions including: which is the optimal cutoff value of female bladder voiding efficiency during uroflow to suspect obstruction or detrusor underactivity? Is there a definition of pure underactive and pure obstructed voiding in females? Is there a place to distinguish those relatively obstructed from those relatively underactive females especially in those cases of equivocal obstruction? Current measures of contractility were reviewed for their usefulness in women. RESULTS No recommendation for a specific index or calculation can be made based on current knowledge. "Contractility" may be context-dependent regarding clinical care, clinical prognostication, and physiologic research. CONCLUSIONS This group proposes that context-sensitive definitions of "Contractility" deserve attention by international leadership. Cooperative clinical and physiologic expertise will be needed to achieve this goal. Following initial recommendations based on expert opinion, the development of final definitions and measures of contractility should be iterative, based upon validation studies to be considered as part of the definitional process.

Abstract
OBJECTIVE To investigate the clinical characteristics and useful signs to differentiate detrusor underactivity from bladder outlet obstruction in men with non-neurogenic lower urinary tract symptoms. METHODS A total of 638 treatment-naive men with non-neurogenic lower urinary tract symptoms who underwent subjective and objective evaluations were reviewed retrospectively. We divided the patients into detrusor underactivity and bladder outlet obstruction groups based on urodynamic findings, and compared parameters obtained from questionnaires and non-invasive tests. Detrusor underactivity was defined as bladder contractility index ≤100 and bladder outlet obstruction index ≤40, whereas bladder outlet obstruction was defined as bladder contractility index >100 and bladder outlet obstruction index >40. RESULTS Of 638 patients, 145 (22.7%) had detrusor underactivity and 273 (42.8%) had bladder outlet obstruction. Total international prostate symptom score and international prostate symptom score-voiding subscore were significantly higher in the detrusor underactivity group. There were significant differences in prostate volume, intravesical prostatic protrusion, and all uroflowmetry parameters between the two groups. In multivariate logistic regression analysis, lower intravesical prostatic protrusion (cut-off value 8.2 mm), lower bladder voiding efficiency (cut-off value 70%), and the presence of sawtooth and interrupted waveform on uroflowmetry were significant predictive factors for detrusor underactivity. In particular, the incidence of sawtooth and interrupted waveform was significantly higher in the detrusor underactivity group (80%) than in the bladder outlet obstruction group (12.8%), which showed both high sensitivity (80%) and specificity (87.2%) in differentiating detrusor underactivity from bladder outlet obstruction. CONCLUSIONS Sawtooth and interrupted waveform on uroflowmetry can be a useful predictive factor for detrusor underactivity. In addition, lower intravesical prostatic protrusion and bladder voiding efficiency can be of supplementary use.

Abstract
AIMS To identify the clinical and urodynamic factors associated with the large capacity bladder and incomplete bladder emptying after prolapse repair. METHODS We identified 592 women who underwent anterior and/or apical prolapse repair at our institution from 2009 to 2015. Women were stratified by urodynamic capacity. The primary outcome was incomplete emptying at the longest follow-up (postvoid residual [PVR] > 200 mL). Data were analyzed in the Statistical Analysis System software. RESULTS Two hundred and sixty-six women (mean age, 61 years) had preoperative urodynamic tracings available for review. After surgery, there were 519 PVRs in 239 women recorded at up to 2949 days (mean, 396) and nine time points (median, 2; IQR, 1-3). The receiver operator curve for predicted probability of longest follow-up PVR greater than 200 mL (area under curve = 0.67) identified the 600 mL cutpoint which defined large capacity bladder. Large capacity bladders (capacity, >600 mL [n=79] vs ≤600 mL, [n=160]) had a mean: detrusor pressure at maximum flow (21 vs 22 cm H2 O; P = 0.717), maximum flow rate (19 vs 17 mL/s; P = 0.148), significantly elevated PVR (202 vs 73 mL; P < 0.001), and significantly lower voiding efficiency (VE) (74 vs 82%, P < 0.05). Following prolapse repair, elevated PVR was associated with large capacity (PVR 101 vs 49 mL, P < 0.05). Large bladders had a two- to three-fold risk of longest follow-up PVR greater than 200 mL (14.3%-20.3% [capacity, >600 mL] vs 4.1%-7.0% [capacity, ≤600 mL]). VE was similar after surgery regardless of the capacity (87% vs 88%, P = 0.772). CONCLUSIONS The decision to pursue prolapse repair should be individualized and take into account, the bladder capacity and goals for PVR improvement after surgery.

Abstract
INTRODUCTION In the development of terminology of the lower urinary tract, due to its increasing complexity, the terminology for male lower urinary tract and pelvic floor symptoms and dysfunction needs to be updated using a male-specific approach and via a clinically-based consensus report. METHODS This report combines the input of members of the Standardisation Committee of the International Continence Society (ICS) in a Working Group with recognized experts in the field, assisted by many external referees. Appropriate core clinical categories and a subclassification were developed to give a numeric coding to each definition. An extensive process of 22 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS A Terminology Report for male lower urinary tract and pelvic floor symptoms and dysfunction, encompassing around 390 separate definitions/descriptors, has been developed. It is clinically-based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in male lower urinary tract and pelvic floor dysfunction. Male-specific imaging (ultrasound, radiology, CT, and MRI) has been a major addition whilst appropriate figures have been included to supplement and help clarify the text. CONCLUSIONS A consensus-based Terminology Report for male lower urinary tract and pelvic floor symptoms and dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

Abstract
To investigate whether the maximum Watts factor (WF) is 1 parameter of describing detrusor contraction in male patients with lower urinary tract symptoms (LUTS).We retrospectively reviewed urodynamic data of male subjects with LUTS. Data on age, maximum flow rate (Qmax), post-void residual (PVR), detrusor pressure at maximum flow rate (PdetQmax), maximum Watts factor (WFmax), and Schafer contractility grades were collected. First, all patients were divided into 6 groups according to Schafer contractility grade. The urodynamic parameters include WFmax and bladder contractility index (BCI) were compared and analyzed among the 6 groups by using Kruskal-Wallis test statistically. The box plot of Schafer contractility grade with WFmax or BCI were plotted and analyzed. Second, the correlation scatter diagram between WFmax and BCI was plotted and analyzed. Spearman's correlation test was performed. Third, we drew the Receiver Operating Characteristic (ROC) curve and confirmed the area under the curve, the Optimal Operating Point (OOP) and corresponding sensitivity and specificity for WFmax by the reference standard of Schafer contractility grade and BCI respectively.A total of 455 men were included. The mean age of patients was 57 ± 17.9 years, ranging from 18 to 87 years. Median of WFmax increased from 5.8 W/m in very week (VW) group to 19.5 W/m in strong (ST) group, while BCI rose from 70 to 170. The box plot of Schafer contractility grade with WFmax or BCI showed that both WFmax and BCI were positively correlated with Schafer contractility grade. Kruskal-Wallis test among the 6 groups showed statistically significant difference (P <.001). The correlation scatter diagram showed that WFmax increased significantly with BCI (), the linear regression equation being Y = 3.33 + 0.07X, R2 = 0.298. Spearman's correlation test revealed that WFmax and BCI were positively correlated, with the correlation coefficient being 0.616 (P <.001). The WFmax area under ROC curve by Schafer contractility grade was 0.894 and WFmax OOP was interpreted at 11.1 W/m. In addition, the area under ROC curve by BCI was 0.802 and WFmax OOP was interpreted at 9.8 W/m.Our findings suggestted that WFmax was a good parameter of evaluating detrusor contraction as well as Schafer contractility grade and BCI, which should be widely used in clinical.

Abstract
CONTEXT Detrusor underactivity (DUA) is a common but relatively under-researched bladder dysfunction. Underactive bladder (UAB) is the symptom-based correlate of DUA. Recently, there has been renewed interest in this topic. OBJECTIVE To systematically review and summarise the most recent literature and discuss this in the context of what is already known. EVIDENCE ACQUISITION A systematic review of the literature was performed in December 2017 using Medline and Scopus databases. Separate searches of each database used a complex search strategy including "free text" protocols. Search terms included "underactive bladder", "detrusor underactivity", "acontractile bladder", "detrusor failure", "detrusor areflexia", "atonic bladder", "chronic retention", and "impaired bladder contractility". EVIDENCE SYNTHESIS The initial search retrieved a total of 1690 studies; of these 44 were included in the final analyses. CONCLUSIONS Although there has been an expansion in the literature concerning all aspects of DUA and UAB, knowledge on its epidemiology and aetiopathogenesis is still lacking; there remains a need to develop accurate reproducible diagnostic criteria and effective treatments, in particular drug therapies. PATIENT SUMMARY Recently, there has been renewed interest in underactive bladder with expanding research in this area. The lack of simple, reproducible, noninvasive diagnostic criteria has precluded an accurate estimation of the magnitude of the problem. Recent studies have highlighted the potential role of impaired bladder blood supply in causing bladder underactivity.

Abstract
AIMS To test the significance of association between a validated index of detrusor contractility, vCE , the Watts Factor, and the Detrusor Contractility Parameter, t20-80 ; and to test whether t20-80 depends on outflow tract resistance as indicated by Bladder Outlet Obstruction Index (BOOI). METHODS Thirty-seven pressure-flow traces from 20 male and 17 female patients were analyzed and forms of the Watts Factor, t20-80 and BOOI were compared with vCE . RESULTS The Detrusor Contractility Parameter, t20-80 , is significantly associated with vCE for both women and men without a high degree of bladder outlet obstruction. The Watts Factor only had a significant association with vCE at the point of maximum flow in women. CONCLUSIONS The Detrusor Contractility Parameter (DCP) (t20-80 ), can be measured easily from the pressure flow curves of a urodynamic test. The Watts Factor at maximum urine flow, WFQmax , can be readily calculated, but is only applicable to women. In both women and men without a high degree of bladder outlet obstruction, DCP is better associated with true detrusor contractility than any Watts Factor analysis.

Abstract
OBJECTIVE Despite high-grade intravesical prostatic protrusion (IPP) being closely related to bladder outlet obstruction (BOO), up to 21% of patients with low IPP remain obstructed. This study evaluates the characteristics and urodynamic findings of men with small prostates and low IPP. METHODS One hundred and fourteen men aged >50 years old with lower urinary tract symptoms (LUTS) were assessed with symptoms, uroflowmetry, serum prostate-specific antigen (PSA), transabdominal ultrasound measurement of prostate volume (PV), IPP and post-void residual urine (PVRU). All patients underwent pressure flow studies. Patients with PV < 30 mL and IPP ≤ 10 mm were examined for parameters correlating with BOO or impaired detrusor contractility. RESULTS Thirty-six patients had PV < 30 mL and IPP <10 mm. Nine patients (25.0%) had urodynamic BOO, all with normal bladder contractility. Fourteen patients (38.9%) had poor detrusor contractility and all had no BOO. PV, PVRU and IPP were significantly associated with BOO, with IPP showing greatest positive correlation. Both Qmax and IPP were significantly associated with detrusor contractility. At 5-year follow-up, most patients responded to medical therapy. Only three out of nine patients (33.3%) with BOO eventually underwent surgery, and all had a high bladder neck seen on the resectoscope. Only one patient (7.1%) with poor detrusor contractility eventually required surgery after repeat pressure flow study revealed BOO. CONCLUSION In men with small prostates and low IPP, the presence of BOO is associated with higher PV, PVRU and IPP, and most respond well to medical management. BOO can possibly be explained by elevation of the bladder neck by a small subcervical adenoma.

Abstract
PURPOSE OF REVIEW Underactive Bladder (UAB) is an emerging concept of voiding dysfunction, building on a tradition of often overlapping and confusing terminologies describing the patient experience, urodynamic function, and pathophysiology. This confusion of symptoms with function with pathology has hampered development of an effective disease model. RECENT FINDINGS As with other urinary symptoms, the relationship of voiding symptoms to urodynamic dysfunction is variable. Efforts are underway to formally define UAB as a collection of symptoms related to voiding. Defined as voiding symptoms, UAB cannot be reliably linked to detrusor underactivity (DU) nor to detrusor weakness. SUMMARY Progress will be made by characterizing the functional disorders underlying UAB symptoms, examining the biology of these linkages, re-conceptualizing urinary control as one part of a more global biologic adaptive physiology, and determining the relationships of central and peripheral pathologies leading to disrupted control mechanisms.

Abstract
The prevalence of lower urinary tract (LUT) symptoms increases with age but the etiology is unknown. This article aims to identify research directions that clarify the basis of this association. The initial question is whether biological age is the variable of interest or a time-dependent accumulation of factors that impact on LUT function at rates that differ between individuals. In particular, the accumulation of conditions or agents due to inflammatory states or tissue ischemia is important. Much of the above has been concerned with changes to bladder function and morphology. However, the outflow tract function is also affected, in particular changes to the function of external sphincter skeletal muscle and associated sacral motor nerve control. Nocturia is a cardinal symptom of LUT dysfunction and is more prevalent with aging. Urine production is determined by diurnal changes to the production of certain hormones as well as arterial blood pressure and such diurnal rhythms are blunted in subjects with nocturia, but the causal links remain to be elucidated. Changes to the central nervous control of LUT function with age are also increasingly recognized, whether in mid-brain/brainstem regions that directly affect LUT function or in higher centers that determine psycho-social and emotional factors impinging on the LUT. In particular, the linkage between increasing white matter hyperintensities and LUT dysfunction during aging is recognized but not understood. Overall, a more rational approach is being developed to link LUT dysfunction with factors that accumulate with age, however, the precise causal pathways remain to be characterized. Neurourol.

Abstract
Underactive bladder (UAB) is an expanding troublesome health issue, exerting a major influence on the health and independence of older people with a disproportionally low level of attention received. The 2nd International Congress on Underactive Bladder (CURE-UAB 2) convened in Denver, CO on December 3 and 4, 2015, and comprised of top clinicians, scientists, and other stakeholders to address the challenges in UAB. A series of workshops aimed to define UAB and its phenotype, define detrusor underactivity (DU) and create a subtyping of DU, evaluate existing animal models for DU, and lastly to establish research priorities for UAB.

Abstract
Purpose Though urodynamic study (UDS) is the current established standard to distinguish between detrusor underactivity (DU) and bladder outlet obstruction (BOO), concerns of patient discomfort and potential complications of catheterization deters its use. We inspected clinical variables to discriminate between DU and BOO in uroflowmetry, which can be more easily performed in clinical practice. Materials and Methods Total 240 men who both underwent UDS and uroflowmetry were reviewed. The patients were divided into 2 groups by a single experienced urologist based on UDS outcome; DU (n=111) and BOO (n=129). From uroflowmetry, 5 variables including maximal flow rate (Qmax), average flow rate (Qave), voiding volume (VV), postvoid residual urine (PVR), and value of Qmax minus Qave (DeltaQ) was obtained. Multivariable analysis including receiver operating characteristic (ROC) curve analysis was performed to identify the important diagnostic predictors. Results The mean age (±standard deviation) was 65.3±9.2 years. Except Qave, all uroflowmetry components were significantly different between DU and BOO groups. DeltaQ was smaller in DU group (8.71 mL/s vs. 5.26 mL/s, p<0.001). By logistic regression analysis, DeltaQ (Exp(B)=0.648, p<0.001) and PVR (Exp(B)=1.009, p<0.001) significantly discriminate DU and BOO diagnosis. In diagnosing DU using a single variable, the area under the curve of ROC from DeltaQ (0.806) was significantly higher than that from Qmax (0.763, p=0.0126) and Qave (0.574, p<0.0001). Conclusions Our findings suggest that DeltaQ is a novel predictor capable of discriminating DU from BOO in men with obstructive lower urinary tract symptom.

Abstract
PURPOSE Detrusor underactivity (DU) has lately gained increasing interest because this bladder condition is an important cause of post-void residual urine and lower urinary tract symptoms (LUTS) in adult men. Until now, DU can only be diagnosed by pressure-flow measurement. Therefore, the aim of this study was to search for noninvasive tests which can safely predict DU in adult men. METHODS Unselected, treatment-naïve male patients aged ≥40 years with uncomplicated, non-neurogenic LUTS were prospectively evaluated. All men received-after standard assessment of male LUTS-ultrasound detrusor wall thickness (DWT) measurements at a bladder filling ≥250 ml and computer urodynamic investigation. DU was defined as incomplete bladder emptying (>30 ml) in the absence of bladder outlet obstruction or dysfunctional voiding. Classification and regression tree (CART) analysis was used to determine parameters and threshold values for DU. RESULTS The study population consisted of 143 consecutive men with medians of 62 years, IPSS 16, and prostate volume 35 ml. In total, 33 patients (23.1 %) had DU. CART analysis showed that all men with DWT ≤ 1.23 mm plus bladder capacity >445 ml had DU. This multivariate model has a sensitivity of 42 %, specificity of 100 %, positive predictive value of 100 %, and negative predictive value of 85 %. CONCLUSIONS This study showed that all men with ultrasound DWT ≤ 1.23 mm + bladder capacity >445 ml have DU. Combination of these two tests could help physicians to diagnose DU noninvasively in clinical practice. A prospective independent study should confirm these results.

Abstract
The clinical presentation of the neurogenic bladder can be as vast as the pathologic causes however urodynamics (UDS) can help guide clinical decision-making and help simplify a complex disease state. UDS may be considered as the gold standard in helping to break down complex and multifactorial voiding dysfunction into manageable goals; these include protecting the upper tracts, limiting urinary tract infections (UTI) via avoiding urinary stasis, and maintaining quality of life. Included within are examples of normal to pathologic tracings including normal filling and voiding, detrusor sphincteric coordination, changes in compliance, etc. Additionally we have provided expected UDS findings based on neurogenic disease process, including but not limited to, Parkinson’s, dementia, multiple sclerosis (MS) and spinal cord injury based on lesion location. Pattern recognition and understanding of UDS can help lead to quality of life improvements and optimal management for the patient with neurogenic bladder dysfunction.

Abstract
Detrusor underactivity (DU) is a poorly understood dysfunction of the lower urinary tract which arises from multiple etiologies. Symptoms of DU are non-specific, and a pressure-flow urodynamic study is necessary to differentiate DU from other conditions such as overactive bladder (OAB) or bladder outlet obstruction (BOO). The prevalence of DU ranges from 10-48%, and DU is most prevalent in elderly males. The pathophysiology underlying DU can be from both neurogenic and non-neurogenic causes. In this article, we review the neurogenic causes of detrusor underactivity, including diabetic bladder dysfunction, spinal cord injury, multiple sclerosis, Parkinson's disease, cerebrovascular accident, traumatic brain injury, and Fowler's syndrome. As knowledge about the underlying causes of DU advances, there have been several potential therapeutic approaches proposed to help those who suffer from this condition.
