Abstract
PURPOSE Among noninvasive modalities for assessing bladder outlet obstruction (BOO), the penile cuff test (PCT) is the most used in clinical practice. The purpose of this review was to evaluate the performance of PCT in diagnosing and managing BOO. MATERIALS AND METHODS PubMed, Scopus, CINAHL, Embase, Cochrane Library, and Web of Science were searched for studies investigating use of PCT for BOO. Studies evaluating diagnostic parameters, inter-observer agreements, or treatment outcomes using PCT were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol was followed (PROSPERO ID: CRD42022300047). A proportional meta-analysis was done for diagnostic accuracy proportions. The Egger's and the Begg-Mazumdar rank-correlation tests were used to assess publication bias. Risk of bias was assessed using the Gradings of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria. RESULTS Of the 272 articles retrieved, 17 were included in qualitative synthesis and meta-analysis was performed on five studies (comprising 448 patients). Two studies evaluating inter-observer agreement demonstrated 95% agreement and five studies evaluating procedures reported a 66%-80% surgical success rate on obstructed patients using PCT. From the proportional meta-analysis, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 0.85 (95% CI 0.71-0.95) 0.78 (95% CI 0.67-0.87), 0.74 (95% CI 0.52-0.91), and 0.87 (95% CI 0.73-0.96), respectively. Publication bias was noted for PPV but not for sensitivity, specificity, or NPV. Based on the GRADE criteria, there were two low, six moderate, and nine high-quality studies. CONCLUSIONS PCT performs sufficiently in diagnosing and managing BOO. However, due to variability in obstruction criteria assessment, more studies comparing diagnostic criteria are warranted.

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.

Carcinogen Biomarkers in the Urine of Electronic Cigarette Users and Implications for the Development of Bladder Cancer: A Systematic Review. Eur Urol Oncol 2021; 4:766-783. [PMID: 32192941 DOI: 10.1016/j.euo.2020.02.004] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2019] [Revised: 01/19/2020] [Accepted: 02/13/2020] [Indexed: 02/06/2023]
Abstract
CONTEXT Use of electronic cigarettes (e-cigarettes) has rapidly increased despite unclear longitudinal health effects. Once thought to be a safer alternative to tobacco smoke, it is possible that e-cigarettes expose the user to similar carcinogenic byproducts during the vaping process. These toxicants are metabolized and excreted in the urine, and may have oncogenic implications for bladder urothelium. OBJECTIVE To characterize and summarize known urinary carcinogenic biomarkers in e-cigarette users as they relate to the risk of developing bladder cancer. EVIDENCE ACQUISITION A systematic literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and included PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL). Relevant articles published in peer-reviewed journals, through January 2019, that reported on urinary biomarkers in e-cigarettes users were included. Parent compounds and urinary biomarkers were classified according to the International Agency for Research on Cancer Monographs on the Evaluation of Carcinogenic Risks to Humans and cross referenced using the Collaborative on Health and the Environment, Toxicant and Disease Database to determine a link to bladder cancer, grouped by strength of evidence. EVIDENCE SYNTHESIS Our initial search identified 1385 articles, 22 of which met final inclusion criteria and were included for analysis. In summation, these studies described 40 different parent compounds and four metals found in the urine of e-cigarette users. Since each parent compound can be metabolized several different ways, 63 unique toxicant or carcinogenic metabolite biomarkers were identified. Compared with nonuser controls, e-cigarette users had higher concentrations of urinary biomarkers of several carcinogenic compounds linked to bladder cancer. The majority of studies were limited by heterogeneous reporting and a dearth of control individuals who had never smoked. CONCLUSIONS Biomarkers of carcinogens, several with a strong link to bladder cancer, are present in the urine of e-cigarette users. Long-term implications of urothelial exposure to these toxicants are unknown but concerning, given the similarities to tobacco smoke and its established relationship with bladder cancer. Further study on the urological safety of e-cigarettes is necessary. PATIENT SUMMARY Our review shows that several carcinogens that have a known link to bladder cancer are present in the urine of electronic cigarette (e-cigarette) users. Further study on the urological safety of e-cigarettes is necessary.

Abstract
OBJECTIVE Urinary incontinence has a profound impact on women's quality of life. Studies have shown that changes in urinary protein levels could be a potential diagnostic biomarker in some urological diseases. The aim of present study is to determine the diagnostic value of nerve growth factor (NGF) in women with mixed urinary incontinence (MUI) as a diagnostic biomarkers of detrusor overactivity (DO). METHODS Seventy women aged between 20 and 75 years with MUI were enrolled in this prospective study. All participants underwent urodynamic study. Urine NGF levels were measured using an ELISA method. NGF level was compared between groups using Mann-Whitney U test. Receiver Operator Characteristic (ROC) analysis was employed to evaluate the diagnostic performance of urinary NGF. RESULTS The results showed that the median (min, max) of NGF in patients with DO was significantly higher in comparing to its level in women without DO [184.10 (31, 346.60) pg/ml vs. 151.80 (21, 210.70)], respectively (P = 0.035). Using receiver-operator characteristics analysis, the threshold urinary NGF value of 102.00 pg/ml provided a sensitivity of 88% and specificity of 40% in diagnosing DO, PPV of 39.1%, and NPV of 88.2%, positive likelihood ratio 2.18 and negative likelihood ratio of 0.45 (P = 0.02). CONCLUSION Based on high sensitivity and low specificity, we can conclude that NGF can be a good tool for ruling out the OAB when the test is negative. However, the future investigations are needed to expand the observed correlation in larger groups of women with DO.

Comparison of Penile Cuff Test and Conventional Urodynamic Study Prior to Photoselective Vaporization of Prostate for Benign Prostate Hyperplasia Using a 120 W GreenLight High Performance System Laser. J Clin Med 2020; 9:jcm9041189. [PMID: 32326373 PMCID: PMC7231057 DOI: 10.3390/jcm9041189] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 04/17/2020] [Accepted: 04/19/2020] [Indexed: 11/25/2022] Open
Abstract
Background: We compared the utility of the penile cuff test (PCT) and the conventional urodynamic study (UDS) for the preoperative assessment of patients undergoing scheduled photoselective vaporization of the prostate (PVP) for benign prostate hyperplasia (BPH). Methods: Fifty-nine patients with voiding lower urinary tract symptoms (LUTS) underwent a simultaneous PCT and conventional UDS before PVP. The modified International Continence Society (ICS) nomogram was used to confirm bladder outlet obstruction after measuring maximum urinary flow rate and highest pressure at flow interruption. The PCT and UDS results, in terms of modified ICS nomogram predictions, were compared. Their sensitivities, specificities, and positive and negative predictive values were calculated. Results: Thirty-six patients were diagnosed as obstructed and 23 as non-obstructed/equivocal using the modified ICS nomogram during the PCT. All 36 of the first group were confirmed as obstructed by UDS. Of the 23 diagnosed as non-obstructed/equivocal by the PCT, 14 were confirmed to be non-obstructed by UDS, with nine diagnosed as obstructed. The PCT showed a sensitivity of 80% and a specificity of 100%. The positive and negative predictive values were 100% and 60.9%, respectively. Conclusions: In conclusion, despite our small number of patients, the PCT’s high sensitivity and specificity suggest that it may provide diagnostic information about bladder outlet obstruction before PVP for patients with voiding LUTS. Evidently, the PCT has the potential to be used for some patients as a screening alternative to invasive UDS.

Abstract
OBJECTIVE To describe the useful explorations in the clinical evaluation of the symptoms of the lower urinary tract symptoms possibly related to BPH (LUTS/BPH), and to list the information necessary to allow an evaluation of an instrumental or surgical intervention in the treatment of the hypertrophy and benign prostatic obstruction. METHOD Bibliographic research in English using the European, American and French recommendations on the evaluation of BPH, supplemented by a Pubmed search. RESULTS AND CONCLUSIONS A number of systematic investigations into the evaluation of a man with LUTS/BPH include interrogation, clinical examination with rectal examination, urinalysis, flowmeter and post-micturition residual volume. The voiding catalog is necessary to understand the mechanism of a nocturia. PSA has a triple potential of interest: evaluation of the risk of progression, evaluation of the prostatic volume and diagnosis of a cancer of the prostate. Creatinine is needed only when chronic retention is observed and before surgery. Urethrocystoscopy is essential in case of hematuria, suspicion of stenosis of the urethra or bladder tumor. Ultrasound for evaluation of prostate volume is essential before surgery, and may be helpful in guiding the decision to prescribe a 5 alpha reductase inhibitor. No non-invasive technique has proven its possible substitution for pressure flow studies when indicated. When a researcher is considering evaluating a surgical or instrumental treatment for BPH, preoperative, perioperative and follow-up parameters are expected from readers to get a fair idea of the technique being evaluated. LEVEL OF EVIDENCE 5: Consensus d'experts.

Abstract
AIMS This study was focused on the clinical test of an improved and portable version of a previously described urethral connector (UC), designed for minimally invasive measurement of vesical pressure and diagnosis of infravesical obstruction in men. METHODS The conventional pressure-flow study (PFS) and the test with the new version of UC were applied to individuals reporting lower urinary tract symptoms (LUTS), who were then classified as obstructed or non-obstructed/equivocal based on the bladder outlet obstruction index (BOOI) from PFS data. Two-way analysis of variance was used to compare the values of urine flow rate and vesical pressure between methods and diagnoses. RESULTS Vesical pressure and urine flow values were not significantly different between methods (P > 0.05), while the former was greater in the group classified as obstructed. CONCLUSION The present results showed that the UC test can support the diagnosis of infravesical obstruction in a comparable way as that of the conventional urodynamic method, however with the advantages of simplicity and minimal invasiveness, having thus the potential to be an alternative method for long term follow-up of individuals reporting LUTS.

Abstract
OBJECTIVE To investigate the accuracy of the bladder and prostate sonomorphologic parameters for the diagnosis of bladder outlet obstruction (BOO) in patients with lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH). PATIENTS AND METHODS First-visit men, aged ≥ 50 years, with LUTS/BPH were prospectively enrolled. Added to the initial basic evaluation, all patients underwent pelvic ultrasonography and pressure flow study. The pressure flow study was used as a reference standard for BOO, and according to its results, patients were divided into BOO and non-BOO groups. The sonomorphologic findings were compared between both groups, and the diagnostic accuracy of the significant parameters was determined. RESULTS In total, 157 patients were included. Of these, 48 (30.57%) had BOO and 109 (69.43%) did not. Bladder wall thickness (BWT), ultrasound estimated bladder weight (UEBW), and intravesical prostatic protrusion (IPP) were the sonomorphologic parameters that differed significantly between both groups (P < .001). By receiver operating characteristic curve analysis, the optimal cutoff values distinguishing patients with BOO were BWT of 3.7 mm (area under the curve [AUC]: 0.940), UEBW of 31.5 g (AUC: 0.835), and IPP of 10.9 mm (AUC: 0.874). The sensitivity, specificity, and accuracy of BWT, UEBW, and IPP were 95.00%, 90.91%, and 93.55%; 75.44, 57.97%, and 65.62%; and 87.90%, 76.43%, and 82.17%, respectively. CONCLUSION BWT, UEBW, and IPP measurements can be used to detect BOO in LUTS/BPH patients. The simple estimation of these sonomorphologic parameters by suprapubic approach makes these measurements potentially suitable methods to judge BOO noninvasively during the routine clinical evaluation of BPH.

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
PURPOSE The aim of this study was to compare the penile cuff test (PCT) and standard pressure-flow study (PFS) in patients with bladder outlet obstruction. MATERIALS AND METHODS A total of 58 male patients with moderate to severe lower urinary tract symptoms (LUTS) were selected. Seven patients were excluded; thus, 51 patients were finally enrolled. Each of the patients underwent a PCT and a subsequent PFS. The sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and likelihood ratio were calculated. Chi-square and Fisher exact test were used to evaluate relationships between PCT results and maximal urine flow (Qmax); a p<0.05 was considered statistically significant. RESULTS The mean (±standard deviation) age of the study group was 65.5±10.4 years. Overall, by use of the PCT, 24 patients were diagnosed as being obstructed and 27 patients as unobstructed. At the subsequent PFS, 16 of the 24 patients diagnosed as obstructed by the PCT were confirmed to be obstructed, 4 were diagnosed as unobstructed, and the remaining 4 patients appeared equivocal. Of the 27 patients shown to be unobstructed by the PCT, 25 were confirmed to not be obstructed by PFS, with 13 equivocal and 12 unobstructed. Two patients were diagnosed as being obstructed. For detecting obstruction, the PCT showed an SE of 88.9% and an SP of 75.7%. The PPV was 66.7% and the NPV was 93%. CONCLUSIONS The PCT is a beneficial test for evaluating patients with LUTS. In particular, this instrument has an acceptable ability to reject obstruction caused by benign prostatic hyperplasia.

Abstract
OBJECTIVE To investigate the relationship between bladder wall thickness (BWT) and uroflowmetric parameters and the International Prostate Symptoms Score (IPSS) in patients with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS A total of 236 male patients who had LUTS-related benign prostatic enlargement with serum prostate-specific antigen level ≤4 ng/mL were included in this study. Age and duration of LUTS and IPSS were recorded. BWT was measured using 7.5 mHz suprapubic ultrasonography before uroflowmetry and postvoid residual (PVR) was calculated thereafter. The relationship between BWT and poor indicators for bladder outlet obstruction (BOO) (IPSS >19, Qmax <15 mL/min, PVR >100 cm(3)) was investigated. RESULTS The mean age was 62.5 ± 8.1 (39-77) years and the mean BWT was 3.8 ± 1.5 (1.4-8.7) mm. The mean IPSS, Qmax, PVR, and duration of LUTS were 17.7, 13.7 mL/min, 89.9, and 46.5 months, respectively. A positive correlation was found between BWT and IPSS, PVR and duration of LUTS, whereas a negative correlation was found between BWT and Qmax (P <.001). BWT increased when number of BOO parameters increased. BWT was 2.9 in patients without BOO parameters whereas BWT was 3.5, 4.1, and 4.5 mm in patients with any one, any two, and all parameters of BOO, respectively. CONCLUSION BWT increased when number of BOO parameters increased. We believe that measurement of BWT is an easy, quick, and repeatable test to predict BOO severity.

Abstract
CONTEXT Lower urinary tract symptoms (LUTS) represent one of the most common clinical complaints in adult men and have multifactorial aetiology. OBJECTIVE To develop European Association of Urology (EAU) guidelines on the assessment of men with non-neurogenic LUTS. EVIDENCE ACQUISITION A structured literature search on the assessment of non-neurogenic male LUTS was conducted. Articles with the highest available level of evidence were selected. The Delphi technique consensus approach was used to develop the recommendations. EVIDENCE SYNTHESIS As a routine part of the initial assessment of male LUTS, a medical history must be taken, a validated symptom score questionnaire with quality-of-life question(s) should be completed, a physical examination including digital rectal examination should be performed, urinalysis must be ordered, post-void residual urine (PVR) should be measured, and uroflowmetry may be performed. Micturition frequency-volume charts or bladder diaries should be used to assess male LUTS with a prominent storage component or nocturia. Prostate-specific antigen (PSA) should be measured only if a diagnosis of prostate cancer will change the management or if PSA can assist in decision-making for patients at risk of symptom progression and complications. Renal function must be assessed if renal impairment is suspected from the history and clinical examination, if the patient has hydronephrosis, or when considering surgical treatment for male LUTS. Uroflowmetry should be performed before any treatment. Imaging of the upper urinary tract in men with LUTS should be performed in patients with large PVR, haematuria, or a history of urolithiasis. Imaging of the prostate should be performed if this assists in choosing the appropriate drug and when considering surgical treatment. Urethrocystoscopy should only be performed in men with LUTS to exclude suspected bladder or urethral pathology and/or before minimally invasive/surgical therapies if the findings may change treatment. Pressure-flow studies should be performed only in individual patients for specific indications before surgery or when evaluation of the pathophysiology underlying LUTS is warranted. CONCLUSIONS These guidelines provide evidence-based practical guidance for assessment of non-neurogenic male LUTS. An extended version is available online (www.uroweb.org/guidelines). PATIENT SUMMARY This article presents a short version of European Association of Urology guidelines for non-neurogenic male lower urinary tract symptoms (LUTS). The recommended tests should be able to distinguish between uncomplicated male LUTS and possible differential diagnoses and to evaluate baseline parameters for treatment. The guidelines also define the clinical profile of patients to provide the best evidence-based care. An algorithm was developed to guide physicians in using appropriate diagnostic tests.

[PMID: 25527192 PMCID: PMC4289571 DOI: 10.1186/1471-2490-14-103] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2014] [Accepted: 12/11/2014] [Indexed: 11/10/2022] Open
Abstract
Background Aim of this study was to make a comparison between penile cuff test (PCT) and standard pressure-flow study (PFS) in the preoperative evaluation of patients candidates for trans-urethral resection of prostate (TURP) for benign prostatic obstruction (BPO). Methods We enrolled male patients with lower urinary tract symptoms candidates for TURP. Each of them underwent a PCT and a subsequent PFS. A statistical analysis was performed: sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), likelihood ratio and ratio of corrected classified were calculated. Fisher exact test was used to evaluate relationships between PCT and maximal urine flow (Qmax): a p-value < 0.05 was considered statistically significant. Results We enrolled 48 consecutive patients. Overall, at PCT 31 patients were diagnosed as obstructed and 17 patients as unobstructed. At the subsequent PFS, 21 out of 31 patients diagnosed as obstructed at PCT were confirmed to be obstructed; one was diagnosed as unobstructed; the remaining 9 patients appeared as equivocal. Concerning the 17 patients unobstructed at PCT, all of them were confirmed not to be obstructed at PFS, with 10 equivocal and 7 unobstructed. The rate of correctly classified patients at PCT was 79% (95%-CI 65%-90%). About detecting obstructed patients, PCT showed a SE of 100% and a SP of 63%. The PPV was 68%, while the NPV was 100%. Conclusions PCT can be an efficient tool in evaluating patients candidates for TURP. In particular, it showed good reliability in ruling out BPO because of its high NPV, with a high rate of correctly classified patients overall. Further studies on a huger number of patients are needed, including post-operative follow-up as well.

Abstract
PURPOSE To assess the correlation between urodynamic parameters and urinary tract complications linked to benign prostatic enlargement (BPE), as well to assess the possible value of these parameters for predicting complications. METHODS We retrospectively analyzed the relationship between the complications and correlative urodynamic data of 486 BPH patients. Multivariate stepwise logistic regression was used to identify major independent predictors and establish regression models. Receiver operating characteristic (ROC) curves were constructed to evaluate the models' predictive values. RESULTS All of the individual parameters examined significantly correlated with most of the complications linked to BPE, except bladder calculus. According to ROC analysis, all of the areas under ROC curves (AUC), comparison of the individual parameters and the combined effects from the logistical regression models reached statistical significance (p < 0.05), and combining the parameters revealed a higher AUC compared to the individual parameters; however, all of the AUCs were below 0.9. CONCLUSIONS Urodynamic parameters are significantly correlated with most of the complications linked to BPE, and these parameters have predictive value for the occurrence of these complications with limited values.

[PMID: 26558102 PMCID: PMC4442998 DOI: 10.1016/j.aju.2013.06.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2013] [Revised: 06/09/2013] [Accepted: 06/16/2013] [Indexed: 11/23/2022] Open
Abstract
Objective To assess the effect of the urodynamic catheter on the urinary flow rate and residual volume in various urodynamic diagnoses, and compare the outcome when using a smaller catheter, as the effect of this catheter on free uroflow variables is mostly studied in patients with bladder outlet obstruction (BOO) and little is known about its effect in other urodynamic diagnoses. Patients and methods In all, 319 men undergoing a pressure-flow study (PFS) with a 5 F filling and 5 F measuring bladder catheter were subdivided into three groups based on a urodynamic diagnosis, i.e. normal PFS (group 1), BOO (group 2) and detrusor underactivity (DU, group 3). Another group (4) comprised 61 patients who had a PFS with the filling catheter removed before the voiding phase. The effect of the catheters on the maximum urinary flow rate (Qmax) and the postvoid residual volume (PVR) was analysed statistically and compared among the groups. We also compared the free-flow variables with the clinical and urodynamic variables. Results Groups 1–3 (with two catheters) had a significantly lower Qmax and higher PVR than those voiding with one catheter (group 4). The reduction in Qmax was highest in group 3 (41.9%) and least in group 2 (21%). Group 4 showed no significant change in Qmax in cases with BOO and a normal PFS but a significant decline in those with DU (19.6%). The PVR was positively associated with the bladder capacity and negatively with detrusor contractility, but no association with a urodynamic diagnosis of BOO or any specific symptom. Conclusion Detrusor contractility was the strongest predictor of the obstructive effect caused by the catheter. This study justifies the use of a single 5 F catheter at the time of voiding, although that can also cause a reduction in flow in patients with DU.

Abstract
OBJECTIVE To evaluate the change of prostatic elasticity during the development of benign prostatic hyperplasia (BPH) and its correlation with the degree of bladder outlet obstruction (BOO) in the canine model of BOO caused by BPH. MATERIALS AND METHODS Ten male beagle dogs were selected in this study. To establish canine model of BOO caused by BPH, each beagle underwent castration surgery followed by encapsulating the prostate with a double layer of nylon mesh and then treating the beagles with a combination of steroids for 12 weeks. Transrectal ultrasound (TRUS) examination and urodynamic evaluation were performed before and at 4, 8, and 12 weeks of hormone administration. Prostatic volume, Young modulus of prostatic tissue, and urodynamic parameters were compared at each time instance, and the correlation between the Young modulus of the prostatic tissue and urodynamic parameters were evaluated. RESULTS All beagles developed BOO caused by BPH over the time period of the study. Prostatic volume, Young modulus of prostatic tissue, and urodynamic parameters had statistically significant differences before and after 4, 8, and 12 weeks of hormone administration (P <.05). Young modulus of prostatic tissue showed a very significant correlation with urodynamic parameters, including maximum urine flow (Qmax) (r = -0.802, P <.01), Qave (r = -0.711, P <.01), Pves@open (r = 0.638, P <.01), Pves@Qmax (r = 0.699, P <.01), Pdet@Qmax (r = 0.757, P <.01), and Pdetmax (r = 0.739, P <.01). CONCLUSION Young modulus of prostatic tissue increased during the development of the BPH. There was a significant correlation between Young modulus of prostatic tissue and the degree of BOO.

Abstract
Purpose To analyze the effectiveness of tamsulosin 0.2 mg once daily for 3 months according to the degree of intravesical prostatic protrusion (IPP) in patients with benign prostatic hyperplasia (BPH). Materials and Methods A total of 134 BPH patients over 40 years of age treated with tamsulosin 0.2 mg between January 2007 and January 2009 were enrolled retrospectively. The patients were classified into three groups according to the degree of IPP: below 5 mm (group A), between 5 and 10 mm (group B), and over 10 mm (group C). Prostate volume, prostate-specific antigen (PSA), prostatic urethral length (PUL), and prostatic adenoma urethral length (PAUL) were evaluated before treatment. International Prostate Symptom Score and Quality of Life (IPSS/QoL), maximal urine flow rate (Qmax), and postvoid residual (PVR) volume were measured before treatment, and improvement in the three groups was compared after 3 months. Results The mean age of the patients was 65.01±7.38 years. Mean IPPs were 0.90±1.39 mm (group A, n=90), 6.92±1.10 mm (group B, n=24), and 16.60±4.06 mm (group C, n=20). Prostate volume, PUL, PAUL, PSA, Qmax, and PVR showed significant correlations with IPP (p<0.05), but not with IPSS/QoL score (p>0.05). Comparison of parameters before and after 3 months showed that medication improved total IPSS and subscores (p<0.001), QoL (p<0.001), Qmax (p<0.001), and PVR (p=0.030) in group A. In group B, it improved total IPSS (p=0.01), irritative subscore (p<0.001), and obstructive subscore (p=0.03). In group C, only total IPSS (p=0.01) and irritative score (p<0.001) were significantly improved. Conclusions Tamsulosin may be more effective in improving symptom scores and Qmax in patients with mild IPP than in those with moderate or severe IPP.

Abstract
AIMS To review clinical studies thus have been conducted to develop non-invasive diagnostic tools in the storage phase of the micturition cycle. METHODS Pub Med and Web of Science searches were carried out. The search covered the published data of non-invasive diagnostic techniques for detrusor overactivity (DO) and/or low compliance bladder in patients with urinary storage symptoms. The patho-physiological and clinical relevance of these methods were addressed. Diagnostic accuracy of these techniques was scrutinized. RESULTS Eighteen studies were included in the review. Ultrasonography and biomarkers were the most investigated techniques in the diagnosis of storage disorders. Assessment of diagnostic accuracy was possible in four studies. The heterogeneity in data reporting was too high to conduct a meta-analysis. Ultrasonographic parameters and cut-off values have been developed to define DO; such as bladder wall thickness (BWT), detrusor wall thickness and bladder weight. The likelihood ratio of vaginal ultrasonography in measurement of BWT was good. Guidelines are currently developing to standardize the methodologies applied in these techniques. Laboratory biomarkers of DO are gaining more attention recently, but their specificity for DO should be carefully defined. Near infrared spectroscopy (NIRS) is potential non-invasive diagnostic method that is able to detect the DO episodes in real time. However, a solution needs to be found for motion artifacts in this technique. CONCLUSION Non-invasive diagnostic techniques for storage disorders show limited progress with some limitations. Yet these techniques still cannot replace the standard filling cystometry in standard clinical practice.
