Purpose of review: There is a long history of implantation of absorbable and nonabsorbable materials to treat stress urinary incontinence (SUI) and pelvic organ prolapse (POP). The focus of this review is to review the development of new materials for use in the surgical management of both pelvic conditions following an unacceptable level of severe complications in the use of polypropylene mesh (PPM). We discuss current concepts relating to the development of new materials with particular reference to our experience with polyurethane mesh.

Recent findings: Our review highlights the strategies that manufacturers and researchers are employing to improve PPM using collagen gels and stem cells, or to find alternatives. We conclude that current preclinical safety testing is inadequate, and the field requires better in vivo testing. Specifically, we highlight novel techniques demonstrating the degradation of polypropylene potentially elucidating the link between PPM degradation and induction of inflammation leading to adverse side effects.

Summary: This field badly needs innovation in developing new materials and in testing these to ensure materials will benefit patients. A collaboration between materials scientists and clinicians is needed to facilitate the translation of basic research and preclinical testing into patient benefit for the treatment of SUI and POP.

Purpose of review: Financial toxicity is a significant concern for many individuals with bladder cancer, which is, overall, the most expensive malignancy, per patient. Financial toxicity, defined as the harmful effects of treatment costs on an individual's quality of life, is associated with worse outcomes and decreased quality of life. Awareness of the objective and subjective factors that contribute to financial toxicity, and ways to mitigate their effects on patients, is essential to reduce the burden of bladder cancer care. This commentary aims to discuss the elements contributing to financial toxicity amongst bladder cancer patients, identify at-risk populations, and review current and potential strategies for mitigating financial burden.

Recent findings: Bladder cancer is becoming more expensive as the use of novel therapies increases. Early data suggest how some of these novel treatments or changes in treatment delivery may impact costs. Potential innovative strategies for cost reduction include blue light cystoscopy, intravesical gemcitabine-docetaxel rather than BCG for high-risk nonmuscle-invasive patients, home BCG therapy, and surveillance guideline optimization. However, there is still much work to be done on the potential impacts of these treatment on financial toxicity. While there is a paucity of data on treatment changes to reduce financial toxicity, and cost data can be hard to access, clinicians can still reduce the financial burden of cancer care. Awareness, financial toxicity screening, cost communication, and/or early referral to financial navigators or other similar resources have the potential to reduce financial burden. Despite mounting evidence, these tools/techniques are largely underutilized.

Summary: Many individuals with bladder cancer face significant financial toxicity, with the potential for this to worsen in the setting of rising treatment costs. Novel diagnostic and treatment modifications may reduce financial toxicity. However, awareness, screening, cost discussions, and utilization of financial navigators are tools/techniques that are currently available and should be used to reduce financial burden.

Purpose of review: The literature was reviewed for all noninvasive central nervous system (CNS) stimulation techniques, which includes transcranial brain or trans-spinal stimulation, in the aging population. Given the rising ubiquity of this technology, noninvasive nature, and low side-effect profile reported, this technology can have a big impact on the aging population. As patients afflicted with neurogenic disorders are living longer lives, a special emphasis is placed on the aging neurogenic population.

Recent findings: Noninvasive CNS stimulation techniques have been applied to major bladder and pelvic floor disorders such as voiding dysfunction, chronic pelvic pain, urgency and urge incontinence, lower urinary tract dysfunction, and situational urge incontinence in both the idiopathic and neurogenic populations. Overall, these noninvasive technologies demonstrate effectiveness for the treatment of these conditions with some studies showing effectiveness with longer-term follow-up suggesting lasting CNS remodeling.

Summary: Most manuscripts had a generally small number of patients and an even smaller number of geriatric patients represented. No studies were specifically designed to investigate geriatric outcomes. It is the hope of this systematic review to help model future studies according to existing literature, but with a focus on the geriatric population as they stand to gain the most from noninvasive technologies with limited adverse events.

Purpose of review: While there is an established association between the use of anticholinergic medications and its effects on cognition, the extent of this impact remains unclear. We outline recent studies addressing this topic.

Recent findings: We describe a series of recent articles discussing the risk of dementia associated with anticholinergic medication use in general, with further focus on the risk of overactive bladder (OAB) anticholinergic use, detailing short & long-term use effects, risk variation based on age and gender, and reporting alternative treatment options.

Summary: Anticholinergic medication use bears an increased risk of dementia development, and accelerated cognitive decline in individuals with preexisting dementia, with the risk being related to the medications dosages, length of exposure, and pharmacological profile. β3-adrenoceptor agonists have proven to be a potent alternative for OAB anticholinergics, owing to its safe profile in regards of no clear effects on cognitive function, and having similar efficacy in OAB treatment.

Purpose of review: The focus of this review is to present recent literature and gaps in knowledge (GIKs) surrounding the current and future treatment and prevention of uncomplicated recurrent urinary tract infections (rUTIs) in women.

Recent findings: Recurrent urinary tract infections are common, significantly reduce quality of life, and create a substantial economic burden to the healthcare system. They are disproportionately affecting the postmenopausal women. Antibiotics, which are used for the treatment and prophylaxis of uncomplicated rUTI, have become problematic, as there is a global rise in allergy and resistance to these agents and their use is associated with further antimicrobial resistance. Thus, in recent decades, several alternative, nonantibiotic approaches have been evaluated.

Summary: There is a critical need for a concerted and standardized methodology for diagnosing, treating, and monitoring women with rUTIs. Additionally, novel nonantibiotic alternative treatment and preventive measures for UTIs are desperately required to address the global issue of antibiotic recalcitrance in all age groups, and specifically older women. Research efforts have sought to develop alternative and more effective techniques; many of which appear to be promising, but require additional evaluation and validation through clinical trials.

Purpose of review: There has been a need for an acceptable common minimum data set in the scientific literature as regards the surgical treatment of female stress urinary incontinence (SUI). Such a data set, if widely adopted, would improve the quality of the literature and allow objective comparisons between and across interventions.

Recent findings: The surgical treatment of female stress urinary incontinence has evolved considerably over the past few decades. The corresponding body of literature has grown exponentially describing the outcomes of hundreds of studies of these novel interventions. However, historically, the literature in this space has been of uneven quality. In order to improve the reporting of clinical studies, and ultimately patient outcomes, a standard minimum data set for trial design and publications was created by a collaborative group formed from leading scientific societies.

Summary: The consensus document created from this novel collaboration between members of SUFU (Society of Urodynamics, Female Pelvic Medicine & Urogenital Reconstruction), AUGS (American Urogynecologic Society), and ICS (International Continence Society) provides clear guidance for the structure of clinical studies and reporting of results in the peer-reviewed literature. This has substantial potential ramifications for scientific journals, journal editors, peer reviewers, investigators, regulatory agencies, industry, clinicians, and patients.

Purpose of review: The AMS 800 has dominated the treatment of postprostatectomy urinary incontinence (PPUI) due to intrinsic sphincter deficiency (ISD) for five decades. A narrative review from June 2022 to June 2024 was conducted using 'artificial urinary sphincter' (AUS) MeSH terms in Embase. We extracted information on innovative AUS, randomized controlled trials (RCTs) or prospective studies, and systematic reviews. We evaluated the latest guidelines and consensus and analyzed current trends to discuss options for advancing AUS practices.

Recent findings: Of 465 papers identified, 320 were excluded (irrelevant, duplicates, non-AUS devices, non-English, veterinary), and 145 were reviewed, with 24 selected: seven on novel AUS in development, 7 with higher-level evidence (1 RCT, 1 prospective, 4 systematic reviews, 1 nonsystematic review), and 9 retrospective relevant studies [pressure regulating balloon (PRB), revision strategies, radiotherapy history, manual dexterity/cognition, transscrotal vs. transperineal approach]. The final paper summarized current guidelines from Asia & Pacific on AUS.

Summary: In the past 2 years, six novel AUS have emerged, two female RCTs are ongoing, the SATURN study published its 1-year outcomes, and four systematic reviews on female AUS were conducted. These findings enhance evidence levels and position novel AUS to challenge the Gold Standard.

Purpose of review: Prehabilitation describes interventions that are undertaken prior to a major surgical or medical intervention with the objective of improving functional capability with the goal of improving candidacy for therapy, bolstering one's ability to withstand treatment-associated toxicity, functional decline, and facilitating accelerated recovery. The objective of this review is to detail the key tenets of prehabilitation, synthesize contemporary advances in prehabilitation science within Urologic Oncology , and discuss key methodologic trial design considerations salient to future prehabilitation investigations.

Recent findings: Contemporary prehabilitation clinical trials have primarily evaluated unimodal interventions aiming to improve functional capacity across the domains of physical exercise, nutrition, and cognition with heightened interest in evaluating multimodal interventions addressing two or more domains. Recent investigations have have demonstrated variable improvements in strength, balance, physical function, and quality of life with preoperative exercise. Although presurgical immunonutrition showed promise in other fields, initial results in uro-oncology have not demonstrated reductions in complications nor improvements in early survival. Emerging data supports the potential of multimodal prehabilitation programs to offer more comprehensive benefits, improving functional outcomes, reducing length of stay, and supporting improved recovery.

Summary: To date, early prehabilitation studies in patients undergoing surgery for genitourinary malignancies have demonstrated variable ability to facilitate gains in functional capacity and perioperative outcomes. Key issues have arisen including the need to ensure that interventions are pragmatic, scalable, feasible, and acceptable in these populations that often also have a high prevalence of coincident multimorbidity, frailty, and mental health concerns that can increase risk of adverse outcomes after surgery. The integration of personalized prehabilitation strategies as extensions of perioperative enhanced recovery after surgery protocols, supportive care and survivorship paradigms offers of promise to further engage patients in their care, enhance patient resilience and outcomes, while reducing treatment burden in urologic oncology.

Purpose of review: This review critically evaluates the current state of bladder-sparing options in muscle-invasive bladder cancer (MIBC) and provides an overview of future directions in the field.

Recent findings: Bladder-sparing treatments have emerged as viable alternatives to radical cystectomy (RC) for selected patients with MIBC, especially in those who are unfit for RC or elect bladder preservation. Numerous studies have assessed the efficacy of trimodal therapy (TMT), with outcomes comparable to RC in a subgroup of well selected patients. Combining immunotherapy with conventional treatments in bladder-sparing approaches can yield promising outcomes. Current research is making significant progress in optimizing treatment protocols by exploring new combinations of systemic therapy agents, innovative drug delivery methods, and biomarker-based approaches. Furthermore, clinical markers of response are being tested to ensure adequate response assessment.

Summary: Bladder preservation promise to offer a viable alternative to RC for selected patients with MIBC with the potential to improve patient quality of life. Careful patient selection and ongoing research are essential to optimize patient selection, response assessment, and salvage strategies. As evidence continues to evolve, the role of bladder preservation in MIBC is likely to expand, providing patients with more treatment options tailored to their needs and preferences.
