Neuro-Urology: Call for Universal, Resource-Independent Guidance

Neurogenic lower urinary tract dysfunction (NLUTD), the abnormal function of the lower urinary tract in the context of neurological pathology, has been the subject of multiple efforts worldwide for the development of clinical practice guidelines. These guidelines are based on the same body of evidence, and are therefore subject to the same gaps. For example, sexual and bowel dysfunction in the context of NLUTD, optimal renal function assessment in those who are non-ambulatory or with low muscle mass, optimal upper tract surveillance timing, and modification of diagnostic and treatment modalities for low-resource nations and communities are inadequately addressed. In addition, many aspects of the conclusions and final recommendations of the guidelines are similar. This duplicative work represents a large expenditure of time and effort, which we believe could be focused instead on evidence gaps. Here, we call for a global unified approach to create a single, resource-independent, comprehensive guidance on NLUTD, neurogenic sexual, and neurogenic bowel dysfunction. Targeted research addressing the evidence gaps should be called for and pursued. This will allow for focus to shift to filling the gaps in the evidence for future guidelines

Bladder irrigation with tap water to reduce antibiotic treatment for catheter-associated urinary tract infections: an evaluation of clinical practice

IntroductionCatheter-associated urinary tract infection (CAUTI) is a common complication among patients with urinary catheters and is often treated with antibiotics. With increasing rates of antibiotic resistance, it is necessary to explore alternative treatment options for CAUTIs. The aims of this study were 1) to assess the efficacy and treatment satisfaction of bladder irrigation (BI) with tap water to prevent and treat CAUTIs, 2) and to evaluate the current use of BI for CAUTIs among Dutch clinicians.MethodsThe first part of this study consisted of a cross-sectional study among patients with intermittent or indwelling catheters who performed BI with tap water between March 2020 and May 2021. Efficacy, treatment satisfaction, and Patient Global Impression of Improvement (PGI-I) were assessed using questionnaires. Outcomes were compared between neurogenic lower urinary tract dysfunction (NLUTD) and non-NLUTD patients. Factors associated with overall treatment satisfaction were determined using logistic regression analysis. Second, a nationwide survey of Dutch clinicians was conducted to evaluate the current use of BI for CAUTIs.ResultsA total of 99 patients who were performing BI for at least three months were included. The median age was 61.9 years, 41.4% had NLUTD, and 72.2% performed BI >1 year. The majority of both NLUTD (65.9%) and non-NLUTD patients (68.4%) were (very) satisfied with BI. Women had higher odds of reporting higher satisfaction and each additional CAUTI decreased the odds. Most NLUTD (85.4%) and non-NLUTD (65.5%) patients reported an improvement on the PGI-I with a difference in favour of NLUTD patients (p=0.002). In addition, 40.4% of the patients had no CAUTI, and 59.6% reported 1.39 (SD 2.06) CAUTIs. Only half of these self-reported CAUTIs were treated with antibiotics. In addition, 33 (58.9%) clinicians used BI for CAUTIs, of which ten used tap water as irrigation agent.DiscussionThis study provides first evidence supporting the efficacy of BI with tap water in the treatment of CAUTIs and reducing the use of antibiotics. Patients are overall satisfied and experience improvement in their condition with BI. In addition, the majority of the surveyed Dutch clinicians use BI for CAUTIs. However, irrigation with tap water is still not widely used

Programming settings and recharge interval in a prospective study of a rechargeable sacral neuromodulation system for the treatment of overactive bladder

Aims: The RELAX-OAB study is designed to confirm the safety, efficacy, and technical performance of the Axonics r-SNM System, a miniaturized, rechargeable SNM system approved in Europe and Canada for the treatment of bladder and bowel dysfunction. The purpose of this article is to describe study subjects’ ability to charge the rechargeable neurostimulator and to document their neurostimulator program settings and recharge interval over time. Methods: Fifty-one OAB patients were implanted in a single-stage procedure. These results represent the 3-month charging experience for 48 subjects who completed the 3-month follow-up. Recharge intervals were estimated using therapy stimulation settings and subject experience was evaluated using questionnaires. Results: Forty-seven of forty-eight (98%) subjects were able to successfully charge their device prior to follow-up within 1-month post-implant. At 3-month post-implant, 98% of subjects were able to charge prior to their follow-up visit. Average stimulation amplitude across all subjects was 1.8 mA (±1.1 mA). A total of 69% of subjects had ≥14-day recharge intervals (time between charging) and 98% of subjects had ≥7-day recharge interval. No charging related adverse events occurred. Conclusions: Study subjects were able to charge the Axonics r-SNM System and stimulation settings provided 2 weeks of therapy between recharging for most subjects. Subject satisfaction indicates that subjects are satisfied with rechargeable SNM therapy

One-year outcomes of the ARTISAN-SNM study with the Axonics System for the treatment of urinary urgency incontinence

Aims: Sacral neuromodulation (SNM) is a guideline-recommended treatment for voiding dysfunction including urgency, urge incontinence, and nonobstructive retention as well

Surgery for stress urinary incontinence in women: A 2006 review

The surgical treatment of female stress urinary incontinence is a rapidly changing field. This review discusses recent advances in various injectables, minimally invasive techniques and open procedures. It particularly evaluates data from long-term outcome studies and describes peri- and postoperative complications from several procedures, such as bulking agents, tension-free vaginal tape and its modifications (TOT, TVT-O) as well as open and laparoscopic colposuspension
