OBJECTIVES: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative urinary function in elderly patients undergoing total hip arthroplasty (THA). METHODS: One hundred and eighty elderly patients undergoing unilateral THA without indwelling urinary catheters were randomly assigned to a TEAS group (90 cases, 3 cases dropped out, 4 cases were eliminated) and a sham TEAS group (90 cases, 1 case dropped out, 4 cases were eliminated). Both groups received fascia iliac block and subarachnoid block anesthesia under ultrasound guidance. The patients in the TEAS group were treated with TEAS at Zhongji (CV 3), Guanyuan (CV 4), and bilateral Huiyang (BL 35), Ciliao (BL 32) 30 minutes before anesthesia initiation, with dissperse-dense wave, frequency of 2 Hz/100 Hz, until 30 minutes after surgery. The patients in the sham TEAS group underwent the same procedure with the device applied at the same acupoints but without electrical stimulation. The incidence of postoperative urinary retention (POUR), time to first void, voiding threshold, urinary adenosine triphosphate (ATP) level, postoperative abnormal voiding status (bladder residual volume, re-catheterization rate, nocturia occurrence), and postoperative incidence of urinary tract infection (UTI) and prosthetic joint infection (PJI) were observed in both groups. RESULTS: The incidence of POUR in the TEAS group was lower than that in the sham TEAS group (P<0.05); the time to first void in the TEAS group was shorter than that in the sham TEAS group (P<0.05); the voiding threshold in the TEAS group was lower than that in the sham TEAS group (P<0.05); the urinary ATP level in the TEAS group was higher than that in the sham TEAS group (P<0.05); the bladder residual volume in the TEAS group was lower than that in the sham TEAS group (P<0.05); the nocturia occurrence in the TEAS group was lower than that in the sham TEAS group (P<0.05). However, there was no statistically significant difference in re-catheterization rate, incidence of UTI, and incidence of PJI between the two groups (P>0.05). CONCLUSIONS: TEAS could effectively reduce the occurrence of postoperative urinary retention and improve the postoperative urinary function in elderly patients undergoing THA, which might be related with increasing the urinary ATP level.

Effects of Transcutaneous Tibial Nerve Stimulation in Women Refractory to and Never Used Pharmacological Agents for Idiopathic Overactive Bladder.

INTRODUCTION AND HYPOTHESIS: The aim of this study is to compare the effectiveness of transcutaneous tibial nerve stimulation (TTNS) on quality of life (QoL) and clinical parameters related to incontinence in pharmacological agents (PhAs) naive and refractory women with idiopathic overactive bladder (iOAB). METHODS: In this prospective nonrandomized clinical trial, women with resistance to PhAs were included in the first group (n=21), PhA-naive women were included in the second group (n=21). TTNS was performed 2 days a week, a total of 12 sessions for 6 weeks. Every session lasted 30 min. Women were evaluated for the severity of incontinence (Pad test), 3-day voiding diary (voiding frequency, nocturia, incontinence episodes, and number of pads), symptom severity (Overactive Bladder Questionnaire-V8), quality of life (Incontinence Impact Questionnaire-7), treatment satisfaction, positive response, and cure-improvement rates. RESULTS: A statistically significant improvement was found in all parameters for each group at the 6th week compared with the baseline values (p<0.05). It was found that the severity of incontinence, incontinence episodes, symptom severity, treatment satisfaction, and QoL parameters were significantly improved in PhA-naive group compared with the PhA-resistant group at the 6th week (p<0.05). There were no statistically significant differences in the frequency of voiding, nocturia, and number of pads between the two groups (p>0.05). Positive response rates, the primary outcome measure, were statistically significantly higher in the PhA-naive group than in the PhA-resistant group. CONCLUSIONS: Although TTNS is more effective in PhA-naive women with iOAB, it appears to be an effective therapy that can also be used in the management of PhA-resistant women with iOAB.

Effectiveness of auricular acupuncture and pelvic floor muscle training in the management of urinary incontinence following surgical treatment for prostate cancer: A randomized clinical trial.

PURPOSE: To evaluate the effectiveness of auricular acupuncture combined with pelvic floor muscle training to manage urinary incontinence following radical prostatectomy. METHODS: This is a randomized clinical trial that was conducted between April 2019 and April 2020 with 60 participants allocated into two groups, namely: control (pelvic muscle training) and intervention (auricular acupuncture + pelvic muscle training). Interventions were carried out during eight weekly sessions. Generalized estimating equations and proportion difference tests were applied in the statistical analysis with a significance level of 0.05. RESULTS: Urinary incontinence severity decreased between pre-test and post-test in both groups. There was a statistically significant difference of the impact of urinary incontinence on quality of life between the groups at post-test in the domain "severity measures" (p = 0.013), and only in the intervention group between pre-test and post-test in the domains "emotions" (p < 0.001) and "sleep and mood" (p = 0.008). The intervention group was 20.8% (p = 0.007) and 25.3% (p = 0.002) less likely to present nocturia and urinary urgency, respectively. CONCLUSIONS: Auricular acupuncture combined with pelvic floor muscle training was more effective, compared to pelvic floor muscle training alone, in reducing the impact of urinary incontinence on quality of life and reducing the odds of nocturia and urinary urgency.

Differences in the urinary metabolome and proteome between wet and dry nights in children with monosymptomatic nocturnal enuresis and nocturnal polyuria.

BACKGROUND: Nocturnal enuresis (NE) is a common disease with multiple pathogenic mechanisms. This study aimed to compare levels of metabolites and proteins between wet and dry nights in urine samples from children with monosymptomatic NE (MNE). METHODS: Ten boys with MNE and nocturnal polyuria (age: 7.6 ± 1.3 years) collected their total nighttime urine production during a wet and a dry night. Untargeted metabolomics and proteomics were performed on the urine samples by liquid chromatography coupled with high-mass accuracy tandem mass spectrometry (LC-MS/MS). RESULTS: On wet nights, we found reduced urine osmolality (P = 0.025) and increased excretion of urinary potassium and sodium by a factor of, respectively, 2.1 (P = 0.038) and 1.9 (P = 0.19) compared with dry nights. LC-MS identified 59 metabolites and 84 proteins with significantly different levels between wet and dry nights (fold change (FC) < 0.67 or > 1.5, P < 0.05). Some compounds were validated by different methodologies. During wet nights, levels of compounds related to oxidative stress and blood pressure, including adrenalin, were increased. We found reduced levels of aquaporin-2 on wet nights. The FCs in the 59 metabolites were positively correlated to the FCs in the same metabolites identified in urine samples obtained during the evening preceding wet and dry nights. CONCLUSIONS: Oxidative stress, which in the literature has been associated with nocturia and disturbances in sleep, might be increased during wet nights in children with MNE. We further found evidence of increased sympathetic activity. The mechanisms related to having wet nights in children with MNE seem complex, and both free water and solute handling appear to be important.

'Nocturomics': transition to omics-driven biomarkers of nocturia, a systematic review and future prospects.

OBJECTIVE: To systematically review studies that investigated different biomarkers of nocturia, including omics-driven biomarkers or 'Nocturomics'. MATERIALS AND METHODS: PubMed® , Scopus® , and Embase® were searched systematically in May 2022 for research papers on biomarkers in physiological fluids and tissues from patients with nocturia. A distinction was made between biomarkers or candidates discovered by omics techniques, referred to as omics-driven biomarkers, and classical biomarkers, measured by standard laboratory techniques and mostly thought from pathophysiological hypothesis. RESULTS: A total of 13 studies with 18 881 patients in total were included, eight of which focused on classical biomarkers including: atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP), C-reactive protein (CRP), aldosterone, and melatonin. Five were 'Nocturomics', including one that assessed the microbiome and identified 27 faecal and eight urinary bacteria correlated with nocturia; and four studies that identified candidate metabolomic biomarkers, including fatty acid metabolites, serotonin, glycerol, lauric acid, thiaproline, and imidazolelactic acid among others. To date, no biomarker is recommended in clinical practice. Nocturomics are in an embryonic phase of conception but are developing quickly. Although candidate biomarkers are being identified, none of them are yet validated on a large sample, although some preclinical studies have shown a probable role of fatty acid metabolites as a possible biomarker of circadian rhythm and chronotherapy. CONCLUSION: Further research is needed to validate biomarkers for nocturia within the framework of a diagnostic and therapeutic precision medicine perspective. We hope this study provides a summary of the current biomarker discoveries associated with nocturia and details future prospects for omics-driven biomarkers.

Physical and Rehabilitation Therapy for Overactive Bladder in Women: A Systematic Review and Meta-Analysis.

Objective: To compare the effects of different physical and rehabilitation therapies on women with overactive bladder (OAB). Design: Network meta-analysis. Data source: The Embase, Scopus, and PubMed databases were systematically searched from their inception to June 22, 2022. We included only RCTs, with no language restrictions. Articles in the reference lists and related studies were thoroughly reviewed. Review Methods. This network meta-analysis included related studies on different physical and rehabilitation therapies for OAB. Data were extracted independently from the included randomized controlled trials by two authors, and they used the Cochrane Collaboration's tool to evaluate the risk of bias. We used RevMan to assess the risk assessment of research bias. This network meta-analysis was performed using the Stata software. We completed the review in accordance with the PRISMA items for systematic reviews and meta-analyses statement. Results: Twelve randomized controlled trials involving 637 patients were included in this meta-analysis. All physical and rehabilitation therapies improved daytime micturition frequency and nocturia frequency in OAB patients. Percutaneous tibial nerve stimulation (PTNS), BT + ES, and BT + BF + ES are better interventions for OAB treatment. There were no significant differences in PTNS, BT + ES, and BT + BF + ES. Conclusion: All physical and rehabilitation therapies can improve daytime micturition and nocturia frequency in OAB. PTNS, BT + ES, and BT + BF + ES were the priority therapies.

[Effect of auricular acupressure combined with 5α-reductase inhibitor on short-term quality of life of patients after transurethral plasmakinetic enucleation of the prostate].

OBJECTIVE: To evaluate the effect of combined application of Semen vaccariae seeds auricular acupressure and 5α-reductase inhibitor (finasteride tablets) on postoperative quality of life of patients after transurethral plasmakinetic enucleation of the prostate (PKEP). METHODS: 120 patients with benign prostatic hyperplasia (BPH) who were scheduled to undergo PKEP at the Department of Urology, Jintan People's Hospital Affiliated to Jiangsu University from January 2020 to December 2022, were randomly divided into 4 groups after voluntarily signing informed consent. Three days before the operation, 30 patients were given oryzanol tablets 5 mg orally once a night (placebo group), 31 patients were given Semen vaccariae seeds auricular acupressure (auricular acupressure group), 29 patients were given finasteride 5 mg orally once a night (finasteride group), and another 30 patients were given auricular acupressure combined with finasteride 5 mg orally once a night (combination therapy group). The above treatment was continued for 6 weeks after PKEP. The general data of the perioperative period and the 6-week postoperative follow-up results of the 4 groups were compared to observe the indicators such as the symptom score of nocturia, the self-rating depression scale, and the quality of life (QoL) after treatment among the groups. RESULTS: All patients who underwent PKEP completed the 6-week postoperative follow-up and no statistical difference in the relevant data of the 4 groups was found before the operation. After 2 and 4 weeks of follow-up, the nocturia symptom scores of the auricular acupressure group and the combination therapy group were better than those of the placebo group and the finasteride group. The depression symptom scores and QoL results showed that the auricular acupressure group, finasteride group, and combination therapy group were superior to the placebo group (P<0.05). After 6 weeks of follow-up, QoL in the combination therapy group was 1.65±0.55, which was significantly different from that in the other three groups (P<0.05). CONCLUSION: Combined application of auricular acupressure and 5α-reductase inhibitor can significantly alleviate symptoms such as nocturia and depression and improve the quality of life in BPH patients after PKEP.

Acupuncture for treating overactive bladder in adults.

BACKGROUND: Overactive bladder is a common, long-term symptom complex, which includes frequency of micturition, urgency with or without associated incontinence and nocturia. Around 11% of the population have symptoms, with this figure increasing with age. Symptoms can be linked to social anxiety and adaptive behavioural change. The cost of treating overactive bladder is considerable, with current treatments varying in effectiveness and being associated with side effects. Acupuncture has been suggested as an alternative treatment. OBJECTIVES: To assess the effects of acupuncture for treating overactive bladder in adults, and to summarise the principal findings of relevant economic evaluations. SEARCH METHODS: We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (including In-Process, Epub Ahead of Print, Daily), ClinicalTrials.gov and WHO ICTRP (searched 14 May 2022). We also searched the Allied and Complementary Medicine database (AMED) and bibliographic databases where knowledge of the Chinese language was necessary: China National Knowledge Infrastructure (CNKI); Chinese Science and Technology Periodical Database (VIP) and WANFANG (China Online Journals), as well as the reference lists of relevant articles.  SELECTION CRITERIA: We included randomised controlled trials (RCTs), quasi-RCTs and cross-over RCTs assessing the effects of acupuncture for treating overactive bladder in adults. DATA COLLECTION AND ANALYSIS: Four review authors formed pairs to assess study eligibility and extract data. Both pairs used Covidence software to perform screening and data extraction. We assessed risk of bias using Cochrane's risk of bias tool and assessed heterogeneity using the Chi2 testand I2 statistic generated within the meta-analyses. We used a fixed-effect model within the meta-analyses unless there was a moderate or high level of heterogeneity, where we employed a random-effects model. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: We included 15 studies involving 1395 participants in this review (14 RCTs and one quasi-RCT). All included studies raised some concerns regarding risk of bias. Blinding of participants to treatment group was only achieved in 20% of studies, we considered blinding of outcome assessors and allocation concealment to be low risk in only 25% of the studies, and random sequence generation to be either unclear or high risk in more than 50% of the studies. Acupuncture versus no treatment One study compared acupuncture to no treatment. The evidence is very uncertain regarding the effect of acupuncture compared to no treatment in curing or improving overactive bladder symptoms and on the number of minor adverse events (both very low-certainty evidence). The study report explicitly stated that no major adverse events occurred. The study did not report on the presence or absence of urinary urgency, episodes of urinary incontinence, daytime urinary frequency or episodes of nocturia. Acupuncture versus sham acupuncture Five studies compared acupuncture with sham acupuncture. The evidence is very uncertain about the effect of acupuncture on curing or improving overactive bladder symptoms compared to sham acupuncture (standardised mean difference (SMD) -0.36, 95% confidence interval (CI) -1.03 to 0.31; 3 studies; 151 participants; I2 = 65%; very low-certainty evidence). All five studies explicitly stated that there were no major adverse events observed during the study. Moderate-certainty evidence suggests that acupuncture probably makes no difference to the incidence of minor adverse events compared to sham acupuncture (risk ratio (RR) 1.28, 95% CI 0.30 to 5.36; 4 studies; 222 participants; I² = 0%). Only one small study reported data for the presence or absence of urgency and for episodes of nocturia. The evidence is of very low certainty for both of these outcomes and in both cases the lower confidence interval is implausible. Moderate-certainty evidence suggests there is probably little or no difference in episodes of urinary incontinence between acupuncture and sham acupuncture (mean difference (MD) 0.55, 95% CI -1.51 to 2.60; 2 studies; 121 participants; I2 = 57%). Two studies recorded data regarding daytime urinary frequency but we could not combine them in a meta-analysis due to differences in methodologies (very low-certainty evidence). Acupuncture versus medication Eleven studies compared acupuncture with medication. Low-certainty evidence suggests that acupuncture may slightly increase how many people's overactive bladder symptoms are cured or improved compared to medication (RR 1.25, 95% CI 1.10 to 1.43; 5 studies; 258 participants; I2 = 19%). Low-certainty evidence suggests that acupuncture may reduce the incidence of minor adverse events when compared to medication (RR 0.34, 95% CI 0.26 to 0.45; 8 studies; 1004 participants; I² = 51%). The evidence is uncertain regarding the effect of acupuncture on the presence or absence of urinary urgency (MD -0.40, 95% CI -0.56 to -0.24; 2 studies; 80 participants; I2 = 0%; very low-certainty evidence) and episodes of urinary incontinence (MD -0.33, 95% CI -2.75 to 2.09; 1 study; 20 participants; very low-certainty evidence) compared to medication. Low-certainty evidence suggests there may be little to no effect of acupuncture compared to medication in terms of daytime urinary frequency (MD 0.73, 95% CI -0.39 to 1.85; 4 studies; 360 participants; I2 = 28%). Acupuncture may slightly reduce the number of nocturia episodes compared to medication (MD -0.50, 95% CI -0.65 to -0.36; 2 studies; 80 participants; I2 = 0%, low-certainty evidence). There were no incidences of major adverse events in any of the included studies. However, major adverse events are rare in acupuncture trials and the numbers included in this review may be insufficient to detect these events. AUTHORS' CONCLUSIONS: The evidence is very uncertain about the effect acupuncture has on cure or improvement of overactive bladder symptoms compared to no treatment. It is uncertain if there is any difference between acupuncture and sham acupuncture in cure or improvement of overactive bladder symptoms. This review provides low-certainty evidence that acupuncture may result in a slight increase in cure or improvement of overactive bladder symptoms when compared with medication and may reduce the incidence of minor adverse events. These conclusions must remain tentative until the completion of larger, higher-quality studies that use relevant, comparable outcomes. Timing and frequency of treatment, point selection, application and long-term follow-up are other areas relevant for research.

Complementary therapies in the control of male lower urinary tract symptoms: A systematic review. / Terapias complementares no controle de sintomas do trato urinário inferior masculino: revisão sistemática.

OBJECTIVE: to evaluate diverse scientific evidence on the effectiveness of complementary therapies in the control of lower urinary tract symptoms in the adult and aged male population. METHOD: a systematic review developed according to the PRISMA checklist. The search was performed in the CINAHL, Embase, LILACS, PEDro, PubMed, Web of Science and Google Scholar databases. RESULTS: a total of 585 records were identified and 12 clinical trials were selected that met the inclusion criteria. The outcomes considered by the studies for analyzing effectiveness of the complementary therapies were validated questionnaires to assess the severity of the lower urinary tract symptoms (sensation of incomplete bladder emptying, frequent urination, intermittent flow, weak flow, pain or difficulty urinating, nocturia and urgency) and urodynamics parameters. The studies analyzed the complementary phytotherapy (n=8) and electroacupuncture (n=4) therapies. Six studies related to phytotherapy showed statistical significance. Electroacupuncture showed a significant improvement in the symptoms in two studies. CONCLUSION: pytotherapy was effective to control the simptoms related to frequency, urgency, nocturia, incomplete emptying, intermittence, weak flow and effort to initiate urination. To confirm the effectiveness of electroacupuncture, research studies with well-designed methodologies will also be necessary to resolve the divergences between the studies of this review.

The effectiveness of different electrical nerve stimulation protocols for treating adults with non-neurogenic overactive bladder: a systematic review and meta-analysis.

INTRODUCTION AND HYPOTHESIS: Electrical nerve stimulation is a widely used treatment for overactive bladder but there is no consensus regarding the best placement of electrodes or protocols. We hypothesised that some non-implanted neurostimulation protocols would be more effective compared to others for treating urinary symptoms and improving quality of life among adults diagnosed with non-neurogenic overactive bladder. METHODS: A systematic review and meta-analyses of randomized clinical trials were performed in five electronic databases: PubMed/MEDLINE, Lilacs, CINAHL, Web of Science, and PEDro. The main outcome was urinary symptoms-frequency, nocturia, and urgency-and the secondary outcome quality of life. Some protocol characteristics were extracted, e.g., frequency, pulse width, intensity, intervention time, and electrode placement. RESULTS: Nine randomized controlled trials were included. Tibial neurostimulation showed better results than sacral neurostimulation for urge incontinence (mean difference = 1.25 episodes, 95% CI, 0.12-2.38, n = 73). On the pooled analysis, the different neurostimulation protocols-intravaginal, percutaneous tibial, and transcutaneous tibial nerve stimulation-demonstrated similar results for urinary frequency, nocturia, and urgency as well as quality of life. In general, effect sizes from meta-analyses were low to moderate. The best reported parameters for percutaneous tibial nerve stimulation were 20-Hz frequency and 200-µs width, once a week. CONCLUSIONS: There was evidence that tibial neurostimulation is more effective than sacral neurostimulation for urge incontinence symptoms among patients with non-neurogenic overactive bladder. Overall, there was no superiority of an electrical nerve stimulation electrode placement and protocol over others considering urinary symptoms and quality of life. Further studies with three-arm trials are necessary. This study was registered at PROSPERO: CRD4201810071.

The association between nocturia, hormonal symptoms and bladder parameters in women: an observational study.

OBJECTIVE: Postmenopausal nocturia is poorly understood. This study aimed to identify hormonal and lifestyle factors associated with nocturia and to understand the relative contribution of altered urine production and bladder storage dysfunction in women. DESIGN, SETTING, POPULATION AND METHODS: Women ≥40 years presenting to public continence services were enrolled in a cross-sectional study. A total of 153 participants completed a hormone status questionnaire, a validated nocturia causality screening tool and a 3-day bladder diary. Descriptive statistics and logistic regression models for nocturia severity and bladder diary parameters were computed. RESULTS: Overall, 91.5% reported nocturia, 55% ≥2 /night. There was a difference of 167.5 ml (P < 0.001) in nocturnal urine volume between women with nocturia ≥2 (median 736 ml) versus less often (517 ml). Significant predictors of self-reported disruptive nocturia were age (odds ratio [OR] 1.04, 95% CI 1.002-1.073) and vitamin D supplementation (OR 2.33, 95% CI 1.11-4.91). Nocturnal polyuria was significantly more common with nocturia ≥2 compared with less frequent nocturia (P < 0.002). Exercise for 150 minutes a week was protective for nocturnal polyuria (OR 0.22, P = 0.001). Nocturia index >1.3 was significantly predicted by age (OR 1.07, P < 0.001), regular exercise (OR 0.41, P = 0.036), day flushes (OR 4.00, P = 0.013) and use of vitamin D (OR 2.34, P = 0.043). Maximum voided volumes were significantly lower with nocturia ≥2 versus less often (night: 268 ml versus 350 ml; day: 200 ml versus 290 ml). CONCLUSIONS: Bothersome nocturia in postmenopausal women is associated with changes to both nocturnal diuresis and bladder storage. Regular physical activity, prolapse reduction and oestrogen replacement may be adjunctive in managing bothersome nocturia in women.

The effects of choreito on a model of nocturnal polyuria using Dahl salt-sensitive rats.

OBJECTIVES: This study aimed to determine whether Dahl salt-sensitive rats fed a high-salt diet would show features of nocturia due to nocturnal polyuria and to examine the efficacy of choreito (CRT) on nocturnal polyuria. METHODS: Dahl salt-sensitive rats were divided into three groups. Group A was fed a 4% salt diet, group B a 2% salt diet, and group C a normal 0.3% salt diet. In groups α and ß, other rats were further divided into two groups: The rats in group α were fed a 2% salt plus 3% CRT diet, and those in group ß, were fed a 2% salt diet. Each rat was placed in an individual metabolic cage for 24 hours every week for 6 weeks. Water intake, urine production, voiding frequency, and voided volume per micturition were recorded. RESULTS: The systolic blood pressure increased in the group fed a 4% salt diet compared to groups fed with a 2% and 0.3% salt diet. The urinary volume was higher in the groups fed with 4% and 2% salt than in the group fed with 0.3% salt. Further, water intake in the group fed a 2% salt plus 3% CRT diet was significantly lower than that in the group fed with a 2% salt diet. CONCLUSIONS: Dahl salt-sensitive rats fed a 2% salt diet were candidates for a model of nocturnal polyuria. Using this model, we suggest that CRT reduces water intake in the active phase and contributes to water restriction in the treatment of nocturnal polyuria.

Overactive bladder syndrome in nulliparous female university students: prevalence and risk factors including waterpipe smoking.

INTRODUCTION AND HYPOTHESIS: The objective was to assess the prevalence of symptoms of overactive bladder syndrome (OAB) among healthy nulliparous female university students, and to evaluate the correlation of these symptoms with a variety of factors, including waterpipe (WP) smoking. METHODS: This is a cross-sectional study. A questionnaire was administered to evaluate symptoms of OAB in healthy nulliparous female university students. Variables assessed included body mass index (BMI), cigarette smoking, WP smoking, consumption of alcohol, coffee, and tea with and without artificial sweeteners, soft drinks, and energy drinks. Adjusted odds ratio were calculated to determine the correlation of these variables with OAB symptoms. RESULTS: A total of 767 out of 2,900 females responded to the questionnaire. Bothersome frequency was reported in 32.3%, and nocturia in 47.5% of the women. Urgency and urgency urinary incontinence (UUI) were present in 25.5 and 24.7% of the study participants respectively. Urgency was associated with WP smoking (p value 0.048). Bothersome frequency was associated with artificial sweeteners used with coffee and tea (p value 0.013). UUI was associated with cigarette smoking (p value 0.034) and elevated BMI (p value < 0.001). OAB symptoms were not found to be significantly associated with soft drink and energy drink consumption. A lower prevalence of nocturia (p value 0.009) and urgency was associated with alcohol consumption (p value 0.017). More than two-thirds (69.2%) of WP smokers expressed readiness to decrease WP smoking if this would improve their lower urinary tract symptoms (LUTS). CONCLUSION: Overactive bladder is common in healthy young nulliparous women and is associated with multiple risk factors, including WP smoking.

Do we need more patient-friendly treatment options for overactive bladder (OAB)?

AIMS: To collect feedback from subjects diagnosed with overactive bladder (OAB) on its impact on their quality of life, their satisfaction with current treatment options, and to assess nonsurgical, tibial nerve stimulation as a treatment option. METHODS: Subjects were asked a variety of questions about the impact of OAB on their lives, their satisfaction with current and previous treatment approaches. Subjects evaluated the comfort of a nonworking prototype garment and were given electrical stimulation over their posterior tibial nerve to assess comfort and tolerability. Electromyographic (EMG) signals were recorded. RESULTS: A total of 40 subjects with OAB symptoms were evaluated in the study. Urgency (55%), frequency (47.5%), nocturia (40%), and incontinence (30%) were the most bothersome symptoms. At the time of the study only 32.5% of the subjects were treating their OAB symptoms. Of those that had tried and discontinued treatments, most had failed medications (n = 14) due to no improvements or side effects. Only 2 subjects found stimulation to be uncomfortable before an EMG signal could be detected. The most common word used to describe the feeling of stimulation was "constant," followed by "tingling," "vibrating," and "comfortable." CONCLUSIONS: Most subjects who had tried OAB treatments were dissatisfied and discontinued their use. A new patient-friendly approach to OAB therapy that delivers efficacy but overcomes drawbacks associated with currently available treatments is needed. Subjects found electrical stimulation over the tibial nerve to be comfortable and tolerable and this should be considered as an alternative treatment approach for OAB.

Effectiveness of acupuncture for nocturia: A protocol for systematic review and meta-analysis.

BACKGROUND: Nocturia is a common and highly troubled lower urinary tract symptom, which has a wide range of effects. About 33% of patients with lower urinary tract symptoms have been affected by nocturia. Nocturia is mainly manifested as the increase of urination frequency and urine volume at night. It has been proved that acupuncture can reduce the symptoms of nocturia and regulate bladder function in Western countries. Acupuncture may be a promising choice for the treatment of nocturia. METHODS: RCTs of acupuncture for nocturia will be searched in the relevant database, including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure Wanfang Database, Chinese Biomedical Literature Database, and Chinese Scientific Journal Database. The studies of electronic searches will be exported to EndNote V.9.1 software. We will run meta-analyses using the Review Manager (RevMan) V.5.3 software. Any disagreement will be solved in consultation with a third reviewer. RESULTS: Our study aims to explore the efficacy of acupuncture for nocturia and to provide up-to-date evidence for clinical of nocturia. CONCLUSION: The conclusion of this study will provide evidence for the efficacy of acupuncture treatment of nocturia. INPLASY REGISTRATION NUMBER: INPLASY202130100.

Treatment for overactive bladder: A meta-analysis of transcutaneous tibial nerve stimulation versus percutaneous tibial nerve stimulation.

BACKGROUND: We aim to compare the safety and effectiveness of transcutaneous tibial nerve stimulation (TTNS) versus percutaneous tibial nerve stimulation (PTNS) in treating overactive bladder. METHODS: A systematical search on PubMed, Embase, clinicalTrial.gov, and Cochrane Library Central Register of Controlled Trials from January 1, 1999 to November 1, 2020 was performed. The primary outcomes were the changes in a 3-day voiding diary. Quality of life scores were also evaluated. Review Manager 5.3 (Cochrane Collaboration, Oxford, UK) was applied to conduct all statistical analyses. RESULTS: A total of 4 trials (2 randomized controlled trials, 1 retrospective study, and 1 before-after study) with 142 patients were eventually enrolled. Compared with PTNS, TTNS had a similar performance in the voiding frequency in 24 hours (mean difference [MD] = -0.65, 95% confidence interval [CI]: -1.35 to 0.05, P = .07), the number of urgency episodes in 24 hours (MD = 0.13, 95% CI: -0.36 to 0.62, P = .60), the number of incontinence episodes in 24 hours (MD = 0.01, 95% CI: -0.13 to 0.14, P = .93), as well as in the nocturia frequency (MD = -0.14, 95% CI: -0.52 to 0.24, P = .47). Moreover, comparable results were observed regarding HRQL scores (P = .23) and incontinence quality of life scores (P = .10) in both groups. The total complication rate in the current study was 2.1% (3/142). No adverse events were identified in the TTNS group. CONCLUSION: Current data supported that TTNS is as effective as PTNS for the treatment of overactive bladder, moreover, with no reported adverse events. However, the evidence is low-grade and well-designed prospective studies with a large sample size are warranted to verify our findings.

Auriculotherapy in adults and elderly people with lower urinary tract symptoms: an integrative review.

OBJECTIVE: To analyze the evidence available in the literature on the use of auriculotherapy in adults and elderly people with lower urinary tract symptoms. METHOD: An integrative literature review. Primary study search was carried out in nine relevant health databases. The characterization of studies regarding the method of application of auriculotherapy was based on the Revised Standards for Reporting Interventions in Clinical Trials of Acupuncture recommendations. RESULTS: 296 studies were found, 17 pre-selected and eight included in the review. Favorable results from auriculotherapy were evidenced in specific populations, such as elderly men with prostatic disorders and individuals undergoing surgical procedures. The main urinary symptoms addressed were frequency, urgency, nocturia, incomplete voiding, intermittency, weak flow, effort to start urination, incontinence, and urinary retention. CONCLUSION: Despite the limited number of studies and weaknesses with regard to sample size and different intervention protocols, it is suggested that auriculotherapy, associated or not with other complementary therapies, may contribute to lower urinary tract symptom control in adults and elderly people.

A Systematic Review of Patients' Values, Preferences, and Expectations for the Diagnosis and Treatment of Male Lower Urinary Tract Symptoms.

CONTEXT: Understanding men's values and preferences in the context of personal, physical, emotional, relational, and social factors is important in optimising patient counselling, facilitating treatment decision-making, and improving guideline recommendations. OBJECTIVE: To systematically review the available evidence regarding the values, preferences, and expectations of men towards the investigation and treatment (conservative, pharmacological, and surgical) of male lower urinary tract symptoms (LUTS). EVIDENCE ACQUISITION: We searched electronic databases until August 31, 2020 for quantitative and qualitative studies that reported values and preferences regarding the investigation and treatment of LUTS in men. We assessed the quality of evidence and risk of bias using the Grading of Recommendation, Assessment, Development and Evaluation (GRADE) and GRADE Confidence in the Evidence from Reviews of Qualitative Research (CERQual) approaches. EVIDENCE SYNTHESIS: We included 25 quantitative studies, three qualitative studies, and one mixed-methods study recruiting 9235 patients. Most men reported urodynamic testing to be acceptable, despite discomfort or embarrassment, as it significantly informs treatment decisions (low certainty evidence). Men preferred conservative and less risky treatment options, but the preference varied depending on baseline symptom severity and the risk/benefit characteristics of the treatment (moderate certainty). Men preferred pharmacological treatments with a low risk of erectile dysfunction and those especially improving urgency incontinence (moderate certainty). Other important preference considerations included reducing the risk of acute urinary retention or surgery (moderate certainty). CONCLUSIONS: Men prefer lower-risk management options that have fewer sexual side effects and are primarily effective at improving urgency incontinence and nocturia. Overall, the evidence was rated to be of low to moderate certainty. This review can facilitate the treatment decision-making process and improve the trustworthiness of guideline recommendations. PATIENT SUMMARY: We thoroughly reviewed the evidence addressing men's values and preferences regarding the management of urinary symptoms and found that minimising adverse effects is particularly important. Further research to understand other factors that matter to men is required.

Jingui Shenqi pill for nocturia due to nocturnal polyuria: A protocol for systematic review and meta-analysis.

BACKGROUND: The incidence of nocturia is high and will seriously affect patients' physical and mental health. Nocturnal polyuria is the most critical cause of nocturia, There are few drugs currently used to treat nocturia due to Nocturnal Polyuria (NP). The guide highly recommends only Desmopressin. There is an urgent need to find new drugs. Jingui Shenqi pill (JSP) is a Chinese patent medicine, it is widely used in China to treat NP. However, there is no evidence-based medical evidence to prove its safety and effectiveness. The purpose of this systematic review is to evaluate the efficacy and safety of JSP in the treatment of NP. METHODS: We will search the randomized controlled trials (RCTs) including JSP for NP and published from the inception of the database to Oct 2020 by the following eight databases: Embase, Cochrane Library, PubMed, MEDLINE, the China National Knowledge Infrastructure, Cqvip Database, and Wanfang Data, the Chinese Biomedical Literature Database. There is no language and publication status restriction. The primary outcomes will include Nocturnal urine volume, the number of nocturnal voids, Nocturnal polyuria index (Nocturnal total urine volume /24 h total urine volume). We will perform the data synthesis, sensitivity analysis, subgroup analysis, and bias assessment risk using RevMan V.5.3. The reporting bias will be assessed using a funnel plot and Egger test. RESULTS: This study may provide additional evidence of JSP for NP in the effectiveness and safety and alternative therapy for NP. CONCLUSIONS: In this systematic review, we will assess whether JSP is an effective and safe medicine for nocturia.

Stereotactic Body Radiation Therapy for Intermediate-risk Prostate Cancer With VMAT and Real-time Electromagnetic Tracking: A Phase II Study.

OBJECTIVES: Stereotactic body radiation treatment represents an intriguing therapeutic option for patients with early-stage prostate cancer. In this phase II study, stereotactic body radiation treatment was delivered by volumetric modulated arc therapy with flattening filter free beams and was gated using real-time electromagnetic transponder system to maximize precision of radiotherapy and, potentially, to reduce toxicities. MATERIALS AND METHODS: Patients affected by histologically proven prostate adenocarcinoma and National Comprehensive Cancer Network (NCCN) intermediate class of risk were enrolled in this phase II study. Beacon transponders were positioned transrectally within the prostate parenchyma 7 to 10 days before simulation computed tomography scan. The radiotherapy schedule was 38 Gy in 4 fractions delivered every other day. Toxicity assessment was performed according to Common Terminology Criteria for Adverse Events (CTCAE), v4.0. RESULTS: Thirty-six patients were enrolled in this study. Median initial prostate-specific antigen was 7.0 ng/mL (range: 2.3 to 14.0 ng/mL). Median nadir-prostate-specific antigen after treatment was 0.2 ng/mL (range: 0.006 to 4.8 ng/mL). A genitourinary acute toxicity was observed in 21 patients (dysuria grade [G] 1: 41.7%, G2: 16.7%). Gastrointestinal acute toxicity was found in 9 patients (proctitis G1: 19.4%, G2: 5.6%). Late toxicity was mild (genitourinary toxicity G1: 30.6%; G2: 8.3%; gastrointestinal toxicity G1: 13.9%; G2: 19.4%). At a median follow-up time of 41 months, 3 biochemical recurrences were observed (2 local recurrences, 1 distant metastasis). Three-year biochemical recurrence-free survival was 89.8% (International Society of Urologic Pathology Grade Group 2: 100%, Grade Group 3: 77.1%, P=0.042). CONCLUSION: Ultrahypofractionated radiotherapy, delivered with flattening filter free-volumetric modulated arc therapy and gated by electromagnetic transponders, is a valid option for intermediate-risk prostate cancer.
