Purpose of review: Stress urinary incontinence is a growing issue in ageing men, often following treatment for prostate cancer or bladder outflow obstruction. While implantable urological devices offer relief, infections are a significant concern. These infections can lead to device removal, negating the benefits and impacting patient outcomes. This review explores the risks and factors contributing to these infections and existing strategies to minimize them. These strategies encompass a multifaceted approach that considers patient-specific issues, environmental issues, device design and surgical techniques. However, despite these interventions, there is still a pressing need for further advancements in device infection prevention.

Recent findings: Faster diagnostics, such as Raman spectroscopy, could enable early detection of infections. Additionally, biocompatible adjuncts like ultrasound-responsive microbubbles hold promise for enhanced drug delivery and biofilm disruption, particularly important as antibiotic resistance rises worldwide.

Summary: By combining advancements in diagnostics, device design, and patient-specific surgical techniques, we can create a future where implantable urological devices offer men a significant improvement in quality of life with minimal infection risk.

Purpose of review: Older adults undergoing urologic cancer surgery have unique needs and require unique risk assessment and management. This review will discuss recent literature on brief screening tools to identify high risk older adults in the preoperative period and the role of comprehensive geriatric assessment (CGA) in identifying and addressing geriatric vulnerabilities for older adults undergoing urologic cancer surgery.

Recent findings: Frailty screening tools such as the G8 can be used to identify patients who are at an increased risk of adverse postoperative outcomes such as postoperative complications and prolonged length of stay. CGA can provide more detailed information about geriatric syndromes prior to urologic cancer surgery.

Summary: Screening tools for geriatric vulnerabilities and CGA are valuable tools for the urologist in identifying high-risk older adults, counseling patients on perioperative risk and addressing vulnerabilities prior to surgery. Making health system-wide changes can allow this optimal practice to reach more older surgical patients.

Purpose of review: Several novel therapies approved by the Food and Drug Administration (FDA) and explosion of clinical trials have changed the landscape Bacillus Calmette-Guérin (BCG)-unresponsive nonmuscle invasive bladder cancer (NMIBC). Given the recent advancements in bladder sparing options, the role of radical cystectomy (RC) in BCG-unresponsive NMIBC remains a subject of debate.

Recent findings: All three novel agents currently approved by the FDA for BCG-unresponsive NMIBC have strict indication [carcinoma in situ (CIS)], low response rate, and short response duration. Some promising new agents are awaiting results and/or FDA approval. RC still provides the best oncologic control and acceptable quality of life, and potentially represents the most cost-effective option.

Summary: It is an exciting time for the urologic oncology community to see the FDA approvals of some of the novel bladder sparing therapies and expansion of ongoing clinical trials. Yet, RC should still be considered as the gold standard of BCG-unresponsive NMIBC. We also must be cautious and selective in recommending bladder sparing options for patients with BCG-unresponsive NMIBC.

Purpose of review: The existence of urinary microbiome in healthy individuals is now widely accepted as the longstanding belief in urinary tract sterility was disproved over a decade ago. The urinary microbiome has since been implicated in multiple urologic conditions including urinary tract infection (UTI), urinary incontinence, and bladder cancer. This review relays new findings of urinary microbiome compositional changes associated with aging and UTI susceptibility.

Recent findings: Recent advancements have established how the urinary microbiome changes over the lifespan. Studies finding distinct urinary microbiomes in prepubescent, reproductive age, and postmenopausal females have identified sex hormones as potential modulators of urinary microbiome composition and have identified prevalent species that may be markers of dysbiosis. Research in male children finds a cultivable urinary microbiota that varies with age or urologic history but not delivery mode. Emerging research also addresses the function of the urinary microbiota, including genetic factors associated with urinary tract colonization and interactions with uropathogens.

Summary: The urinary microbiome is a promising therapeutic target for urologic disease. However, a more functional understanding is necessary for the development of microbiome-based therapies. Future research should develop accurate animal models and explore functional relationships between the urinary microbiome and the host environment.

Purpose of review: Natural disasters are on the rise, driven by shifts in climatic patterns largely attributed to human-induced climate change. This relentless march of climate change intensifies the frequency and severity of these disasters, heightening the vulnerability of communities and causing significant harm to both lives and socio-economic systems. Healthcare services are particularly strained during extreme weather events, with impacts felt not only on infrastructure but also on patient care.

Recent findings: This narrative review explored the overarching impact of natural disasters on healthcare infrastructure. We delved into how these disasters impact diverse health conditions, the healthcare systems of low and middle-income countries (LMICs), the psychological toll on both clinicians and survivors, and the ramifications for end-of-life care.

Summary: Natural disasters significantly impact healthcare, especially in LMICs due to their limited resources. Patients with cancer or chronic diseases struggle to access care following a natural disaster. Those in need for palliative care experience delay due to shortages in medical resources. Psychological consequences like posttraumatic stress disorder on disaster survivors and healthcare providers highlight the need for mental health support. Addressing challenges requires proactive disaster preparedness policies and urgent public policy initiatives are needed for optimal disaster response.

Purpose of review: Extremes of weather as a result of climate change are affecting social, economic and health systems. Kidney health is being threatened by global warming while treatment of kidney disease is contributing to increasing resource utilization and leaving a substantial carbon footprint. Improved physician awareness and patient education are needed to mitigate the risk.

Recent findings: Rising temperatures are changing kidney disease patterns, with increasing prevalence of acute kidney injury, chronic kidney disease and kidney stones. These issues disproportionately affect people suffering from social inequality and limited access to resources.

Summary: In this article, we review the effects of climate change on kidney stones, and acute and chronic kidney injury. Finally, we discuss the impact of renal replacement therapies on the environment and proposed ways to mitigate it.

Purpose of review: To review findings related to phantom genital sensation, emphasizing phantom sensation in the transgender and gender diverse (TGD) population. We discuss prevalence, presentation and potential implications for sensory outcomes in genital gender-affirming surgery.

Recent findings: There is a high prevalence of phantom genital sensations in the TGD population. The prevalence varies by body part, approaching 50% in the most frequently reported transgender phantom - the phantom penis. Unlike genital phantoms that occur after trauma or surgery which are often painful, transgender phantoms are typically neutral and often erogenous in experience. Phantom sensation in the TGD population can be an affirming experience and important part of sexual well being and embodiment.

Summary: Recent studies have begun to characterize the prevalence and presentations of phantom genital sensations in TGD people, informing our evolving understanding of the sensory experiences of the transgender and gender diverse population. Targeting integration of these centrally-mediated phantom genital sensations with the peripherally generated sensation from genital stimulation may represent one potential avenue to improve sensation and embodiment following genital gender-affirming surgical procedures. Additionally, emerging techniques in modern peripheral nerve surgery targeting phantom pain may offer potential treatment options for painful phantom sensation seen after cases of genital surgery or trauma.
