The urinary microbiome of participants with interstitial cystitis was less diverse, less likely to contain Lactobacillus species, and associated with higher levels of proinflammatory cytokines. It is unknown whether this represents causality and whether the effect of alterations to the urinary microbiome is mediated through an inflammatory response.

Aims: To describe the association between childhood traumas (death of a family member, severe illness, sexual trauma, parental separation) reported by women and men and lower urinary tract symptoms (LUTS). Methods: In this secondary analysis of the Lower Urinary Tract Research Network Observational Cohort Study, participants completed the LUTS tool, childhood trauma events scale (CTES), PROMIS depression and anxiety and perceived stress scale. LUTS tool responses were combined to quantify urinary urgency, frequency, incontinence, and overall LUTS severity. Multivariable linear regression tested associations between trauma and LUTS; mental health scores were tested for potential mediation. Results: In this cohort (n = 1011; 520 women, 491 men), more women reported experiencing at least one trauma (75% vs. 64%, p < .001), greater than three traumas (26% vs. 15%, p < .001), and childhood sexual trauma (23% vs. 7%, p < .001), and reported higher impact from traumatic events compared with men (median [interquartile rnage] CTES score = 10 [5-15] vs. 6 [4-12], p < .001). The number of childhood traumatic events was not associated with severity of overall LUTS (p = .79), urinary frequency (p = .75), urgency (p = .61), or incontinence (p = .21). Childhood sexual trauma was significantly associated with higher incontinence severity (adjusted mean difference 4.5 points, 95% confidence interval= 1.11-7.88, p = .009). Mental health was a mediator between trauma and LUTS among those with at least one childhood trauma.

Purpose: Lower urinary tract symptoms are prevalent and burdensome, yet methods to enhance diagnosis and appropriately guide therapies are lacking. We systematically reviewed the literature for human studies of biomarkers associated with lower urinary tract symptoms. Materials and Methods: PubMedÒ, EMBASEÒ and Web of ScienceÒ were searched from inception to February 13, 2018. Articles were included if they were in English, performed in benign urological populations without neurological disorders or interstitial cystitis/bladder pain syndrome, and assessed a biomarker's association with or ability to predict specific lower urinary tract symptoms or urological conditions. Bioinformatic pathway analyses were conducted to determine whether individual biomarkers associated with symptoms are present in unifying pathways. Results: Of 6,150 citations identified 125 met the inclusion criteria. Most studies (93.6%) assessed biomarkers at 1 time point and were crosssectional in nature. Few studies adjusted for potentially confounding clinical variables or assessed biomarkers in an individual over time. No individual biomarkers are currently validated as diagnostic tools for lower urinary tract symptoms. Compared to controls, pathway analyses identified multiple immune response pathways that were enriched in overactive bladder

Aims Sacral neuromodulation (SNM) is a guideline‐recommended treatment for voiding dysfunction including urgency, urge incontinence, and nonobstructive retention as well as fecal incontinence. The Axonics® System is a miniaturized, rechargeable SNM system designed to provide therapy for at least 15 years, which is expected to significantly reduce revision surgeries as it will not require replacement as frequently as the non‐rechargeable SNM system. The ARTISAN‐SNM study is a pivotal study designed to treat patients with urinary urgency incontinence (UUI). Clinical results at 1‐year are presented. Methods A total of 129 eligible UUI patients were treated. All participants were implanted with a quadripolar tined lead and neurostimulator in a single procedure. Efficacy data were collected using a 3‐day bladder diary, a validated quality of life questionnaire (ICIQ‐OABqol), and a participant satisfaction questionnaire. Therapy responders were defined as participants with ≥50% reduction in UUI episodes compared to baseline. Data were analyzed on all 129 participants. Results At 1 year, 89% of the participants were therapy responders. The average UUI episodes per day reduced from 5.6 ± 0.3 at baseline to 1.4 ± 0.2. Participants experienced an overall clinically meaningful improvement of 34 points on the ICIQ‐OABqol questionnaire. All study participants (100%) were able to recharge their device at 1 year, and 96% of participants reported that the frequency and duration of recharging was acceptable. There were no serious device‐related adverse events. Conclusions The Axonics System is safe and effective at 1 year, with 89% of participants experiencing clinically and statistically significant improvements in UUI symptoms.
