Prostatic Artery Embolization in Patients with Refractory Lower Urinary Tract Symptoms after a Prior Minimally Invasive Surgical Treatment.

The purpose of this study was to report on prostatic artery embolization (PAE) outcomes in patients with refractory or recurrent lower urinary tract symptoms (LUTSs) due to benign prostatic hyperplasia (BPH) who had previously undergone a minimally invasive surgical technique (MIST). A single-center retrospective study identified 16 eligible patients. Baseline prostate volume at the time of PAE was 112.9 mL (SD ± 52.7). There were no adverse events throughout the follow-up period. There was significant improvement in International Prostate Symptom Score and quality of life from baseline of 23.5 (SD ± 5.1) and 4.9 (SD ± 0.9), respectively, to the last follow-up of 11.6 (SD ± 7.2) and 2 (SD ± 1.6), respectively. There was nonsignificant improvement in sexual function after PAE compared with baseline after MIST. PAE can be a safe and effective treatment in patients who have undergone prior MIST without negatively impacting erectile or ejaculatory function.

Lower urinary tract symptom severity, urinary bother, and incident life-space mobility restriction among older men.

BACKGROUND: Life-space mobility represents the distance, frequency, and independence of mobility, ranging from one's bedroom to beyond their town. Older men with lower urinary tract symptoms (LUTS) may limit their life-space to stay close to a bathroom. However, it's unknown whether LUTS severity or urinary bother are associated with risk of life-space mobility restriction. METHODS: We analyzed data from 3025 community-dwelling men age ≥71 years without life-space mobility restriction at analytic baseline (Year 7) of the Osteoporotic Fractures in Men (MrOS) study. The American Urologic Association Symptom Index (AUASI) was assessed at baseline and includes one question assessing urinary bother ("If you were to spend the rest of your life with your urinary condition just the way it is now, how would you feel about that?"; score 0-1,2,3,4-6) and seven items to classify LUTS severity as none/mild (score 0-7), moderate (8-19), or severe (20-35). The University of Alabama Life-space Assessment was used to define life-space mobility restriction (≤60) at baseline and follow-up (Year 9). We used log-binomial regression with robust variance estimators to model adjusted risk ratios (ARR) for LUTS severity and urinary bother with incident life-space mobility restriction, controlling for age, site, health-related factors, and comorbidities. We then mutually adjusted for urinary bother and LUTS severity. RESULTS: Overall, the 2-year risk of life-space mobility restrictions was 9.9%. Compared to men without urinary bother (scores 0-1), the risk of life-space mobility restriction was significantly higher among men with bother scores of 4-6 (ARR = 2.20, 95% CI: 1.52, 3.19), independent of LUTS severity and confounders. Conversely, LUTS severity was not independently associated with the risk of life-space mobility restriction. CONCLUSIONS: Urinary bother, but not LUTS severity, is independently associated with incident life-space mobility restriction among older men. To maintain life-space mobility in older men with LUTS, future studies should identify shared mechanisms and interventions that minimize urinary bother.

A community-based study on lower urinary tract symptoms in Malaysian males aged 40 years and above.

Lower urinary tract symptoms (LUTS) commonly affecting ageing men and is thought to be linked with other comorbidities and unhealthy lifestyles. This study was performed to report the prevalence of LUTS and its association with quality of life (QOL) in urination and other related factors. The study was part of the National Health and Morbidity Survey (NHMS) 2019, a cross-sectional community-based survey in Malaysia. Validated self-administered bilingual International Prostate Symptom Score (IPSS) was used to assess the LUTS. Other comorbidities and unhealthy lifestyles were recorded using face-to-face interview and in-situ measurements such as anthropometry assessment and blood measurement. There were a total of 2251 respondents. 16.3% of the respondents had clinically significant LUTS (IPSS ≥ 8). LUTS was found to be significantly associated with QOL, age and inactive physical activities. Nocturia was the most prevalent and bothersome symptom. LUTS is a common condition and adversely affect QOL. Ageing and physically inactive males are associated with the development of LUTS. It is recommended to increase public awareness of the condition and availability of treatment options for LUTS. Any upcoming survey should have a more in-depth investigation such as clinical profiling of subjects.

Tadalafil treatment improves cardiac, renal and lower urinary tract dysfunctions in rats with heart failure.

Tadalafil, a phosphodiesterase-5 (PDE5) inhibitor, shown to exert a protection to heart failure (HF) associated damage or lower urinary tract symptoms (LUTS). Thus, we investigated the contribution of tadalafil chronic treatment in the alterations of LUTS in HF rats. Male rats were subjected to aortocaval fistula model for HF induction. Echocardiography, cystometric, renal function and redox cell balance, as well as concentration-response curves to carbachol, KCl, ATP and frequency-response curves to electrical field stimulation (EFS) were evaluated in Sham, HF, Tadalafil and HF-Tadalafil (12 weeks endpoint) groups. HF group to present increased in left-ventricle (LV) mass and in LV end-diastolic- and LV end-systolic volume, with a decreased ejection fraction. Tadalafil treatment was able to decrease in hypertrophy and improve the LV function restoring cardiac function. For micturition function (in vivo), HF animals shown an increase in basal pressure, threshold pressure, no-voiding contractions and decreased bladder capacity, being that the tadalafil treatment restored the cystometric parameters. Contractile mechanism response (in vitro) to carbachol, KCl, ATP and EFS in the detrusor muscles (DM) were increased in the HF group, when compared to Sham group. However, tadalafil treatment restored the DM hypercontractility in the HF animals. Moreover, renal function as well as the oxidative mechanism was impaired in the HF animals, and the tadalafil treatment improved all renal and oxidative parameters in HF group. Our data shown that tadalafil has potential as multi-therapeutic drug and may be used as a pharmacological strategy for the treatment of cardiovascular, renal and urinary dysfunctions associated with HF.

Identifying occult bladder outlet obstruction in women with detrusor-underactivity-like urodynamic profiles.

Voiding dysfunction can result from detrusor underactivity (DU), bladder outlet obstruction (BOO), or both. Conceptually, women with high-pressure low-flow urodynamic profiles are diagnosed with BOO without DU. However, the possibility of BOO is often neglected in women with DU-like (low-pressure low-flow) urodynamic (UDS) profiles. By reviewing the videourodynamic studies (VUDS) of 1678 women, our study identified the key factors suggesting urodynamic BOO (determined by radiographic evidence of obstruction) in women with DU-like UDS profiles (Pdet.Qmax < 20 cmH2O and Qmax < 15 mL/s). In 355 women with DU-like UDS profiles, there were 70 (19.7%) with BOO and 285 (80.3%) without BOO. The BOO group had predominantly obstructive symptoms. The BOO group showed significantly decreased bladder sensation, lower detrusor pressure (Pdet.Qmax), lower flow rate (Qmax), smaller voided volume, and larger post-voiding residual (PVR) compared to the non-BOO group. In multivariate analysis, volume at first sensation, Qmax, PVR, and detrusor overactivity (DO) remained independent factors for BOO. The receiver operating characteristic (ROC) areas for the parameters were largest for PVR (area = 0.786) and Qmax (area = 0.742). The best cut-off points were 220 mL for PVR and 4 mL/s for Qmax. Our findings provide simple indicators for BOO in women with DU.

Patients with renal transplant and moderate-to-severe LUTS benefit from urodynamic evaluation and early transurethral resection of the prostate.

PURPOSE: To assess long-term renal function and micturition pattern of males submitted to transurethral resection of the prostate (TURP) for moderate-to-severe lower urinary tract symptoms (LUTS) after renal transplantation (RT). To investigate the role of clinical and urodynamic (UD) parameters for bladder outlet obstruction (BOO) diagnosis in these patients. METHODS: Retrospective data analysis of ≥ 50 years old patients who underwent RT between 01/2005 and 12/2016. Patients with moderate-to-severe LUTS after RT who underwent a urologic evaluation and a UD study were included. TURP was performed in case of BOO diagnosis. Kidney function and micturition patterns were evaluated before, 3, 12, 24, 36, and 48 months after TURP. Predictors of BOO were assessed at univariable and multivariable logistic regression models. Statistical analysis was performed with STATA16. RESULTS: 233 male patients ≥ 50 years underwent RT. 71/233 (30%) patients developed voiding LUTS. 52/71 (73%) patients with moderate-to-severe LUTS underwent UD. TURP was performed in 36/52 (69%) patients, with BOO diagnosis. Median (interquartile range) follow-up was 108 (75-136) months. Maximum flow at flowmetry (Qmax), International Prostate Symptom Score and post-voided residual volume improved significantly after surgery. Serum creatinine decreased and glomerular filtration rate improved significantly at follow-up, especially when TURP was performed ≤ 6 months from RT. At the multivariable model, bladder capacity ≥ 300 mL (OR = 1.74, CI 95% 1.03-3.15, p = 0.043) and detrusor pressure at Qmax (OR = 2.05, CI 95% 1.48-3.02, p = 0.035) were the independent predictors of BOO. CONCLUSION: RT patients with moderate-to-severe LUTS at risk for BOO and graft failure are better identified by UD than clinical parameters. Bladder capacity and voiding pressure are key for the early diagnosis of BOO.

Characteristics and risk factors of lower urinary tract dysfunction in patients with Parkinson's disease: A systematic evaluation and meta-analysis.

To systematically evaluate the risk factors of lower urinary tract dysfunction in patients with Parkinson's disease(PD), and to provide theoretical basis for clinical medical staff to identify the risk factors of lower urinary tract dysfunction in patients with PD. From the establishment of the database to January 2021, PubMed, the Cochrane Library, EMBASE, Web of Science, other English database, were searched for literatures about the risk factors of lower urinary tract dysfunction in patients with Parkinson's disease. According to the inclusion and exclusion criteria, after browsing the title, abstract and full text, the high-quality literature in line with the inclusion criteria was selected, and the Newcastle-Ottawa Scale（NOS）document quality evaluation tool was used to evaluate the literature quality and extract the data. The included research results were analyzed by RevMan 5.3 software. A total of 8 studies were included for Meta analysis. The results showed that 7 of the 20 related risk factors were statistically significant, and the statistically significant risk factors were duration of disease [Mean Difference (MD)= 0.59, 95% Confidence Interval (CI) (0.04, 1.14), P < 0.005], age [MD = 2.01, 95%CI (-0.36, 3.34), P < 0.005], Hoehn-Yahr (H-Y) score >2 [Odds Ratio (OR) = 1.56, 95%CI (1.09, 2.23), P < 0.001], sleep disorder [OR = 1.79, 95%CI (1.36,2.35), P < 0.001], constipation [OR = 1.88, 95%CI (1.42,2.48), P < 0.001], unified Parkinson's disease rating scale (UPDRS III) [MD= 4.43, 95%CI (2.20, 6.66), P < 0.001], Mini-mental state examination (MMSE) [MD = -1.16, 95%CI (1.23, -1.09), P < 0.001]. Age, duration of disease, H-Y score >2, sleep disorder, constipation, higher UPDRS Ⅲ score and lower MMSE score were the risk factors of lower urinary tract dysfunction in patients with Parkinson's disease.

Evaluation of pedometer use in men with lower urinary tract symptoms: a randomized clinical trial.

PURPOSE: To assess the effect of a pedometer use in men aged between 50 and 59 years presenting lower urinary tract symptoms (LUTS). METHODS: A single-center, not blind clinical trial with two parallel groups and equal randomization was performed with 38 men aged 50-59 years with LUTS. All patients received guidance and encouragement to physical activity practice. Only the intervention group received a Pedometer with a goal of 10,000 steps/day. After a period of 12 weeks, the groups were compared through the following variables: number of steps/day, IPSS score, flexibility, anthropometric values and Maximum Oxygen Consumption (VO2max). RESULTS: The number of steps per day in the intervention group was 9753 ± 1549 compared to 6212 ± 1152 in the control group (p = 0.004). Pedometer use efficacy was a 50% risk reduction of not achieve the goal of 10,000 steps per day. Regarding IPSS score, the intervention group achieved lower scores (6.95 ± 2.85 vs. 10.16 ± 3.23, p = 0.007). Pedometer use efficacy was a 94% risk reduction of not achieve more than 30% reduction in IPSS score. In VO2max, the intervention group performed better than the control group (34.84 ± 3.25 vs. 32.58 ± 6.89; p = 0.011). There was no difference in flexibility and anthropometric values between the groups. CONCLUSIONS: The use of pedometer in LUTS patients provided an increase in the number of steps/day, a decrease in LUTS score and an improvement in VO2max measure.

Perioperative Outcomes of Transurethral Resection, Open Prostatectomy, and Laser Therapy in the Surgical Treatment of Benign Prostatic Obstruction: A "Real-World" Data Analysis from the URO-Cert Prostate Centers.

INTRODUCTION: The aim of the study is to compare length of hospital stay, transfusion rates, and re-intervention rates during hospitalization for transurethral resection of the prostate (TUR-P), open prostatectomy (OP), and laser therapy (LT) for surgical treatment of benign prostatic obstruction (BPO). METHODS: URO-Cert is an organization, in which clinical data of prostatic diseases from 2 university, 19 public, and 3 private hospitals and 270 office-based urologists are collected in order to document treatment quality. Data on diagnostics, therapy, and course of disease are recorded web based. The analysis includes datasets from 2005 to 2017. RESULTS: Of 10,420 patients, 8,389 were treated with TUR-P, 1,334 with OP, and 697 with LT. Median length of hospital stay was 6 days (IQR: 4-7) for TUR-P, 9 days (IQR: 7-11) for OP, and 5 days (IQR: 4-6) for LT (p < 0.001). Risk for a hospital stay ≥7 days was higher for OP versus TUR-P (OR: 7.25; 95% CI = 6.27-8.36; p < 0.001) and LT (OR: 17.89; 95% CI = 14.12-22.65; p < 0.001) and higher for TUR-P versus LT (OR: 2.47; 95% CI = 2.03-3.01; p < 0.001). OP had a significantly higher risk for transfusions than TUR-P (OR: 2.44; 95% CI = 1.74-3.41; p < 0.001) and LT (OR: 3.32; 95% CI = 1.56-7.01; p < 0.001). Transfusion rates were not significantly different between TUR-P and LT (OR: 1.36; 95% CI = 0.66-2.79; p = 0.51). Risk of re-intervention was not different between all 3 approaches. CONCLUSION: OP was associated with higher transfusion rates and longer hospital stay than TUR-P and LT. Risk of transfusion was not different between TUR-P and LT, but TUR-P was inferior to LT concerning length of hospital stay. Re-intervention rates during hospitalization did not differ between the groups.

Therapeutic efficacy of biofeedback pelvic floor muscle exercise in women with dysfunctional voiding.

Dysfunctional voiding (DV), a voiding dysfunction due to hyperactivity of the external urethral sphincter or pelvic floor muscles leading involuntary intermittent contractions during voiding, is not uncommon in neurologically normal women with lower urinary tract symptoms (LUTS). We aimed to investigate the therapeutic efficacy of biofeedback pelvic floor muscle training (PFMT) in female patients with DV and to identify the therapeutic efficacy. Thirty-one patients diagnosed with DV. All participates completed the 3-month biofeedback PFMT program, which was conducted by one experienced physiotherapist. At 3 months after treatment, the assessment of treatment outcomes included global response assessment (GRA), and the changes of clinical symptoms, quality of life index, and uroflowmetry parameters. 25 (80.6%) patients had successful outcomes (GRA ≥ 2), and clinical symptoms and quality of life index significantly improved after PFMT. Additionally, uroflowmetry parameters including maximum flow rate, voided volume, voiding efficiency, total bladder capacity, voiding time, and time to maximum flow rate significantly improved after PFMT treatment. Patients with the history of recurrent urinary tract infection in recent 1 year were found to have unsatisfied therapeutic outcomes. In conclusion, biofeedback PFMT is effective in female patients with DV with significant improvements in clinical symptoms, quality of life, and uroflowmetry parameters. The history of urinary tract infection in recent 1 year is a negative predictor of successful outcome.

Post-void residual urine ratio: A novel clinical approach to the post-void residual urine in the assessment of males with lower urinary tract symptoms.

PURPOSE: To assess the correlation between post-void residual urine ratio (PVR-R) and pathological bladder emptying diagnosed by pressure-flow studies (PFS) in males with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: PVR-R and PVR urine were evaluated in 410 males underwent PFS for LUTS. PVR-R was the percentage of PVR to bladder volume (voided volume+PVR). Schafer and International Continence Society (ICS) nomograms, Bladder Contractility Index (BCI) were used to diagnose bladder outlet obstruction (BOO) and detrusor underactivity (DUA). We subdivided the cohort in 4 groups: Group I, BOO+/DUA+; Group II, BOO-/DUA+; Group III, BOO+/DUA-; Group IV, BOO-/DUA- (control group). We subdivided the 4 groups according to PVR-R strata: (1) 0%-20%; (2) 21%-40%; (3) 41%-60%; (4) 61%-80%; (5) 81%-100%. RESULTS: Group I had a greater median PVR-R (50%) with a >40% in 61.4% of the cohort. Median PVR-R was 16.6% in Group II, 24% in Group III, and 0% in the control Group. According to ICS nomograms and BCI, median PVR-R and PVR were significantly higher (p<0.001) in obstructed and underactive males. PVR-R threshold of 20% allowed to recognize males with voiding disorders with high sensibility, specificity, PPV, and NPV. A PVR-R cut-off of 40% identified males with associated BOO and DUA and more severe voiding dysfunction. CONCLUSIONS: A higher PVR-R is related to a more severe pathological bladder emptying, and to the association of BOO and DUA. PVR-R may have a clinical role in first assessment of males with LUTS and severe voiding dysfunction.

Prevalence and urodynamic characteristics of detrusor overactivity with impaired contractility in the community-dwelling elderly with non-neurogenic lower urinary tract symptoms: Is it from a single or two independent bladder dysfunctions?

PURPOSE: To identify the prevalence of detrusor overactivity with impaired contractility (DOIC) in the community-dwelling elderly and explore whether it is from a single or two independent bladder dysfunctions. MATERIALS AND METHODS: Based on a 10-year urodynamic database of the SEOUL Study Group, elderly patients who met inclusion criteria were selected. Bladder sensation, capacity, and compliance were designated as evaluation elements for storage function, and free maximal flow rate (Qmax) and post void residual volume, detrusor pressure at maximal flow (PdetQmax), and bladder voiding efficiency for voiding function. RESULTS: The prevalence rate of DOIC was 18.8% and 5.5% among 2,571 men and 688 women, respectively, and increased significantly with age. In men, patients with DOIC showed no differences in storage parameters and significantly lower free Qmax and PdetQmax among voiding parameters, compared to those with detrusor overactivity (DO) only. Compared to men with detrusor underactivity (DU) only, those with DOIC had worse parameters in the majority of storage and voiding functions. In women, most of the storage and voiding functions were worse in patients with DOIC than in those with DO only. On the other hand, women with DU showed lower PdetQmax and worse voiding functions than those with DOIC, although some parameters did not reach statistical significance. CONCLUSIONS: It seems that DOIC is developed from a coincidental combination of two independent DO and DU in men. In contrast, DOIC is likely to be an intermediate step during the process of progression from DO to DU in women.

The short-term efficacy of electrical pudendal nerve stimulation versus intravesical instillation for the urethral pain syndrome: a randomized clinical trial.

PURPOSE: Urethral pain syndrome is a chronic condition characterized by disturbing feeling or server pain sensed at the urethra without specific treatment. This double-center, two-arm controlled trial aimed to explore the efficacy of electrical pudendal nerve stimulation (EPNS) versus intravesical instillation (II) of heparin and alkalinized lidocaine for urethral pain syndrome (UPS). METHODS: Eighty eligible patients took three sessions of EPNS, or 1 session of II per week, for 6 consecutive weeks. The primary end point was the change of pelvic pain and urgency/frequency symptom (PUF) score from baseline to week 6. Secondary outcome measures included changes of visual analogue scale (VAS) score and three sub-score extracted from PUF score. RESULTS: The enrolled participants were all included in the intention-to-treat analyses, and baseline characteristics between the two groups were well balanced. The post-treatment PUF score decreased by 10.0 (7.00, 16.50) in the EPNS group, and by 7.0 (3.00, 10.00) in the II group. At the closure of treatment, the medians of changes in symptom score, bother score, pain-related score and VAS score were 6.50 (4.25, 10.00), 4.00 (2.00, 6.00), 6.00 (5.00, 8.00),4.50 (2.25, 6.00), respectively, in the EPNS group, and 4.00 (2.00, 7.00), 3.00 (1.00, 3.00), 3.00 (2.00, 6.00), 2.00 (1.00, 4.00), respectively, in the II group. All the between-group differences were statistically significant. CONCLUSION: Compared with the II, the EPNS results in superior pain control and better relief of lower urinary tract symptoms, and deserves further attention. TRIAL REGISTRATION: ClinicalTrials.gov (NCT03671993).

Mobile sonouroflowmetry using voiding sound and volume.

Uroflowmetry (UF) is a common clinic-based non-invasive test to diagnose Lower Urinary Tract Dysfunction (LUTD). Accurate home-based uroflowmetry methods are needed to conveniently conduct repeated uroflowmetries when patients are physiologically ready to urinate. To this end, we propose and evaluate a novel mobile sonouroflowmetry (SUF) method that estimates the urinary flow rate from a sound signal recorded using a mobile phone. By linearly mapping the total sound energy to the total voided volume, the sound energy curve is transformed to a flow rate curve allowing the estimation of the flow rate over time. An evaluation using data from 44 healthy young men showed high similarity between the UF and SUF flow rates with a mixed-effects model correlation coefficient of 0.993 and a mean root mean square error of 2.37 ml/s. Maximum flow rates were estimated with an average absolute error of 2.41 ml/s. Future work on mobile uroflowmetry can use these results as an initial benchmark for flow rate estimation accuracy.

Cluster analysis of men undergoing surgery for BPH/LUTS reveals prominent roles of both bladder outlet obstruction and diminished bladder contractility.

Lower urinary tract symptoms (LUTS) in aging men are commonly attributed to bladder outlet obstruction from benign prostatic hyperplasia (BPH) but BPH/LUTS often reflects a confluence of many factors. We performed a hierarchical cluster analysis using four objective patient characteristics (age, HTN, DM, and BMI), and five pre-operative urodynamic variables (volume at first uninhibited detrusor contraction, number of uninhibited contractions, Bladder Outlet Obstruction Index (BOOI), Bladder Contractility Index (BCI) and Bladder Power at Qmax) to identify meaningful subgroups within a cohort of 94 men undergoing surgery for BPH/LUTS. Two meaningful subgroups (clusters) were identified. Significant differences between the two clusters included Prostate Volume (95 vs 53 cc; p-value = 0.001), BOOI (mean 70 vs 49; p-value = 0.001), BCI (mean 129 vs 83; p-value <0.001), Power (689 vs 236; p-value <0.001), Qmax (8.3 vs 4.9 cc/sec; p-value <0.001) and post-void residual (106 vs 250 cc; p-value = 0.001). One cluster is distinguished by larger prostate volume, greater outlet resistance and better bladder contractility. The other is distinguished by smaller prostate volume, lower outlet resistance and worse bladder contractility. Remarkably, the second cluster exhibited greater impairment of urine flow and bladder emptying. Surgery improved flow and emptying for patients in both clusters. These findings reveal important roles for both outlet obstruction and diminished detrusor function in development of diminished urine flow and impaired bladder emptying in patients with BPH/LUTS.

Urinary Symptom Nonresponse ("LUTS Failure") after Urethroplasty: Incidence and Associations.

PURPOSE: An ill-defined proportion of patients undergoing urethroplasty fail to experience improvement in lower urinary tract symptoms (LUTS) despite being stricture-free. We aim to identify the incidence, associations and causes of "LUTS failure" after urethroplasty. MATERIALS AND METHODS: Patients undergoing urethroplasty over a 6-year period were offered enrollment in a prospective study examining urinary function after urethroplasty. Patients were assessed preoperatively and 6 months postoperatively using the International Prostate Symptom Score (IPSS) and cystoscopy. "LUTS failure" was defined as ≤3-point improvement in IPSS despite an anatomically successful urethroplasty. Multivariable logistic regression was utilized to evaluate the association between patient factors and "LUTS failure." RESULTS: Of 365 patients meeting inclusion criteria, mean postoperative IPSS (20.3 vs. 5.4, p <0.0001) and median urinary quality of life (UQOL; 5 vs. 1; p <0.0001) were significantly improved. Despite being stricture-free, 7.7% of patients reported "LUTS failure" and 10.1% reported UQOL nonresponse. On multivariable logistic regression, increasing age (OR 1.04, 95% CI 1.01-1.06; p=0.006) and hypospadias (OR 18.2, 95% CI 2.1-156.0; p=0.008) were associated with "LUTS failure," while stricture location (p=0.76), length (p=0.14), previous urethroplasty (p=0.96), failed endoscopic treatment (p=0.17), type of urethroplasty (p=0.93) and other etiologies were not. Qualitatively, the most likely causes of "LUTS failure" were detrusor underactivity (39.3%), overactivity (21.4%), pelvic floor dysfunction (21.4%) or benign prostatic hyperplasia (14.3%). Only increasing age was associated with UQOL nonresponse (OR 1.03, 95% CI 1.01-1.07; p=0.02). CONCLUSIONS: While many patients experience improved voiding function after urethroplasty, 7.7% experience "LUTS failure" and 10.1% report UQOL nonresponse. Both occurrences are independently associated with increasing patient age and most commonly related to detrusor underactivity.

Mechanical and Ablative Minimally Invasive Techniques for Male LUTS due to Benign Prostatic Obstruction: A Systematic Review according to BPH-6 Evaluation.

The treatment of male lower urinary tract symptoms (LUTS) due to benign prostatic obstruction represents one of the major interesting aspects in urological clinical practice. Although transurethral resection of the prostate is still considered the surgical gold standard for treatment of benign prostatic hyperplasia with prostate volume <80 mL, various minimally invasive surgical treatments (MITs) have been developed to overcome the limitations of the "conventional" surgery. To date, there are no validated tools to evaluate the surgical outcomes of MITs; however, in the past, BPH-6 has been used for this purpose. In this systematic review, we evaluated the efficacy and safety of MITs according to BPH-6 score system. We focused our attention on MITs based on mechanical devices (prostatic urethral lift and the temporary implantable nitinol device) and techniques for prostate ablation (image guided robotic waterjet ablation and convective water vapor energy ablation). Evidence shows that MITs are capable of leading to an improvement in LUTS without having an overwhelming impact on complications and are a valid alternative to other treatments in patients who wish to preserve their sexual function or in case of inapplicability of conventional surgery. However, comparative studies between these techniques are still missing.

Disfunción eréctil, síntomas del tracto urinario inferior y calidad de vida en varones mayores de 50 años / Erectile dysfunction, lower urinary tract symptoms, and quality of life in men above 50 years of age

ANTECEDENTES: A nivel mundial, los Síntomas del Tracto Urinario Inferior (STUI) y la Disfunción Eréctil (DE) son un problema relevante de salud pública, especialmente en varones de 50 o más años. Se espera que con el aumento de la esperanza de vida, su prevalencia se incrementa aún más en los próximos años. OBJETIVO: Estimar la prevalencia de los STUI y DE en adultos de 50 años o más de edad y evaluar su relación con la calidad de vida. MATERIAL Y MÉTODOS: Se realizó un estudio transversal analítico a través de una entrevista personal con los participantes. Se emplearon los cuestionarios de disfunción eréctil (IIEF-5), de síntomas prostáticos (IPSS) y la calidad de vida (EuroQoL). Se evaluó la frecuencia y grados de los Síntomas del Tracto Urinario Inferior y Disfunción Eréctil y se correlacionó con la percepción de Calidad de Vida relacionada a la salud en 300 varones mayores de 50 años. Se estimaron medidas sumarias. La asociación de STUI y DE con la calidad de vida fue evaluada con razones de momios (RM) prevalentes e intervalos de confianza (IC) del 95% estimados con modelos de regresión logística no condicional. RESULTADOS: Información de 300 sujetos fue analizada. La prevalencia general de STUI y DE fue 88,3% y 81,7% respectivamente. El 18,3% de los sujetos fueron clasificados como con una calidad de vida muy mala – regular (≤ 60 puntos). En el análisis múltiple, la presencia de STUI moderados (RM = 5,27, 1,08 – 9,73) o severos (RM = 7,05, 1,84 -10,34) se asoció con un incremento en la posibilidad de presentar una menor calidad de vida. CONCLUSIÓN: Nuestros hallazgos sugieren que la disfunción eréctil y los síntomas prostáticos son eventos frecuentes en la población estudiada, al igual que una baja percepción de la calidad de vida. La atención oportuna y eficaz de estas patologías puede potencialmente mejorar la dinámica individual y social de los sujetos afectados

BACKGROUND: Lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) are relevant health problems worldwide, especially in men 50 years of age and older. With the increase in life expectancy, their prevalence is expected to rise in the coming years. AIM: To estimate the prevalence of LUTS and ED in adults 50 years of age and older and evaluate their relation to quality of life. MATERIALS AND METHODS: An analytic cross-sectional study was conducted through a personal interview with the participants. Erectile dysfunction (IIEF-5), prostate symptom (IPSS), and quality of life (EuroQoL) questionnaires were employed. The frequency and grade of LUTS and ED were evaluated and correlated with health-related quality of life perception in 300 men above 50 years of age. Summary measures were calculated. The association of LUTS and ED with quality of life was evaluated with prevalence odds ratios (ORs) and 95% confidence intervals (CIs), calculated using unconditional logistic regression models. RESULTS: Information on 300 subjects was analyzed. The general prevalence of LUTS and ED was 88.3% and 81.7%, respectively. Quality of life was classified as very poor – regular (≤60 points) in 18.3% of the subjects. In the multiple analysis, the presence of moderate LUTS (OR = 5.27, 1.08 – 9.73) or severe LUTS (OR = 7.05, 1.84-10.34) was associated with an increase in the possibility of presenting with a lower quality of life. CONCLUSION: Our findings suggest that erectile dysfunction and prostate symptoms were frequent events in the population studied, as was a low perception of quality of life. The opportune and efficacious treatment of those pathologies can potentially improve the individual and social dynamics of the persons affected

Role of Urodynamic Study in the Management of Pelvic Organ Prolapse in Women.

OBJECTIVES: Pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS) usually coexist and are common among women. Since the efficacy of urodynamic studies (UDS) in evaluating these conditions is subject to controversy, this study aimed to assess the accordance between urodynamic findings and LUTS and to determine the importance of UDS in women with POP. METHODS: This cross-sectional study was conducted on women over 18 years with symptomatic POP referred to the female urology clinic of Kerman University of Medical Sciences, Kerman, Iran, during 2017-2018. Patients who met the inclusion criteria were included in the study with informed consent. The Pelvic Floor Disability Index (PFDI-20) was completed for each patient. Pelvic examination was performed using the Pelvic Organ Prolapse Quantification System (POPQ). Subsequently, multi-channel UDS was performed, and the findings were analyzed in SPSS 20, using Chi-square or Fisher's test. RESULTS: A total of 200 women with symptomatic POP were included in the study. Stress, urge, and mixed urinary incontinence showed significant accordance with the urodynamic findings (urodynamic stress incontinence and/or detrusor overactivity). However, there was no significant relationship between urinary voiding LUTS and urodynamic findings. CONCLUSION: UDS should be performed for selective patients with POP. According to the results of the present study, UDS can help us provide consultation for POP patients with voiding LUTS. However, in POP patients with urinary incontinence, this test cannot provide further information and should be performed based on the patient's condition.

Impact of Age, Education Level and Occupation on the Ability to Use the ICIQ-bladder Diary: Results From A Community Cohort Study Using a Predefined Clinical History.

OBJECTIVE: To assess difficulties in filling the International Consultation on Incontinence Questionnaire Bladder Diary (ICIQ-BD), determining the most troublesome items and patients' characteristics (age, education level, and professional activity) related to these difficulties. METHODS: A text composed of a clinical history of a fictitious patient with Lower Urinary Tract Symptoms (LUTS) was designed. 95 healthy volunteers (49 females, 46 males, mean age 45.6 ± 17.3 years) were asked to fill in the ICIQ-BD according to the data from the fictitious clinical history. Filling errors were analyzed, and patients' demographic characteristics tested as predictors. RESULTS: Bladder Sensation Score is the most problematic item of the ICIQ-BD, with only 38% of patients accurately filling this item. No association was found between total number of errors and age or education level, but participants working in less specialized professions had more difficulty in filling the BD (mean: 7.00 vs 3.94 errors, P= .002). CONCLUSION: ICIQ-BD is a reliable tool to assess for LUTS, but filling the Bladder Sensation Score item was more likely to be incorrectly filled by manual workers and volunteers with less intellectually demanding current professions.
