Bladder pacing in humans through electrical stimulation has shown some potential, although sustainable protocols are lacking owing to detrusor–sphincter dyssynergia and patient discomfort during trials. Thus, manometric studies in brain-dead patients might serve as a model for developing an implantable bladder pacing device to restore contractility.","PeriodicalId":19088,"journal":{"name":"Nature Reviews Urology","volume":"8 1","pages":""},"PeriodicalIF":15.3,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142330317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Health care causes ~5% of global greenhouse gas emissions and other substantial and ongoing environmental harms. Thus, health-care professionals and managers must lead ongoing efforts to improve the environmental performance of health systems. Life-cycle assessment (LCA) is a methodology that enables estimation of environmental impacts of products and processes. It models environmental effects from ‘cradle’ (raw material extraction) to ‘grave’ (end of useful life) and conventionally reports a range of different impact categories. LCA is a valuable tool when used appropriately. Maximizing its utility requires rational assumptions alongside careful consideration of system boundaries and data sources. Well-executed LCAs are detailed and transparently reported, enabling findings to be adapted or generalized to different settings. Attention should be given to modelling mitigation solutions in LCAs. This important step can guide health-care systems towards new and innovative solutions that embed progress towards international climate agreements. Many urological conditions are common, recurrent or chronic, requiring resource-intensive management with large associated environmental impacts. LCAs in urology have predominantly focussed on greenhouse gas emissions and have enabled identification of modifiable ‘hotspots’ including electricity use, travel, single-use items, irrigation, reprocessing and waste incineration. However, the methodological and reporting quality of published urology LCAs generally requires improvement and standardization. Health-care evaluation and commissioning frameworks that value LCA findings alongside clinical outcomes and cost could accelerate sustainable innovations. Rapid implementation strategies for known environmentally sustainable solutions are also needed.</p>","PeriodicalId":19088,"journal":{"name":"Nature Reviews Urology","volume":"58 1","pages":""},"PeriodicalIF":15.3,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142325342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, a successful attempt at urinary bladder autotransplantation was carried out in a heart-beating brain-dead research human donor. The robot-assisted surgical technique was shown to be optimal for performing this procedure, achieving a good performance in terms of both bladder allograft collection as well as vascular, ureterovesical and vesicourethral anastomoses. The urinary bladder vascularized allograft would be an alternative to traditional urinary diversion methods that rely on the use of intestinal segments, potentially avoiding adverse effects associated with these approaches. However, different from ileal urinary diversion, bladder transplantation would require lifelong immune suppression. Clinical trials are in progress to assess the vascularized bladder allograft transplantation technique, as well as the safety of this procedure in oncological and non-oncological indications.","PeriodicalId":19088,"journal":{"name":"Nature Reviews Urology","volume":"77 1","pages":""},"PeriodicalIF":15.3,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142275253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether differences exist in the sperm RNA profile between patients with infertility and fertile men needs clarification. Similarly, the utility of sperm RNAs in predicting successful sperm retrieval and assisted reproductive technique (ART) outcome is unknown. Patients with infertility and fertile individuals seem to have differences in the expression of non-coding RNAs that regulate genes controlling spermatogenesis. Several RNAs seem to influence embryo quality and development. Also, RNA types seem to predict successful sperm retrieval in patients with azoospermia. These findings suggest that sperm RNAs could influence decision-making during the management of patients with infertility. This evidence might help to identify possible therapeutic approaches aimed at modulating the expression of dysregulated genes in patients with infertility. Performing prospective studies with large sample sizes is necessary to investigate cost-effective panels consisting of proven molecular targets to ensure that this evidence can be translated to clinical practice.</p>","PeriodicalId":19088,"journal":{"name":"Nature Reviews Urology","volume":"382 1","pages":""},"PeriodicalIF":15.3,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
