Despite recent technological advances, PPUI remains a common complication and the artificial urinary sphincter (AUS) is regarded as the most effective long-term surgical treatment for moderate-to-severe stress urinary incontinence. Success rates for AUS as defined by a continence status of zero to one pad per day range from 59% to 90%. One potential downside of the AUS is the need for periodic revisions in a number of patients. Revision and explantation rates due to mechanical failure, urethral atrophy, infection and erosion vary considerably among studies with reports of 8-45% and 7-17%, respectively. These complications can be classified into different categories, including recurrent or refractory incontinence, erosion and/or infection, and other complications. This review article aims to describe the main AUS-related complications and their management strategies. Diagnostic work-up strategies are explored to facilitate timely identification and management of these complications. Additionally, emerging technologies and future directions in AUS development are discussed, highlighting potential advancements to mitigate complications and enhance device performance.

Patients that are at the highest risk for such untoward events often possess unhealthy urethral tissue (termed a \"fragile urethra\") that is compromised and unable to provide optimal cuff coaptation and continence. Accordingly, there are several techniques to address recalcitrant SUI in the setting of a fragile urethra to afford an improved chance of return to continence. Here, we review characteristics of patients that are at higher risk for an untoward outcome following AUS implantation and further define strategies to promote optimal success with device implantation. The aim of this paper is to review the available literature and describe surgical options for male SUI in patients with known or anticipated urethral tissue compromise.</p><p><strong>Methods: </strong>A thorough literature review was completed by querying PubMed for relevant articles. Search terms included artificial urinary sphincter, failure, recalcitrant, urethral atrophy, fragile urethra, revision, radiation, cystectomy, incontinence, and/or urethroplasty published between 1975 and 2022.</p><p><strong>Key content and findings: </strong>Options for management of the fragile urethra include cuff relocation, cuff downsizing, tandem cuff placement, transcorporal cuff placement, pressure regulating balloon exchange with increased or decreased pressure, bulbospongiosus preservation, sub-cuff ventral capsulotomy, urethral wrapping with graft, and in select cases, urinary diversion, or complete device removal with a return to SUI. Proper patient selection is paramount to optimize outcomes. Advantages and disadvantages of each strategy are reviewed.</p><p><strong>Conclusions: </strong>Numerous techniques are viable options for patients with recalcitrant SUI in the setting of a fragile urethra, but high-quality evidence with reproducible outcomes for many of these strategies remain limited. Proper patient selection as well as adequate counseling by experienced implant surgeons may help optimize outcomes. Further multi-institutional investigations with longer term outcomes are needed to improve patient selection and counseling with shared decision-making prior to any intervention.</p>","PeriodicalId":23270,"journal":{"name":"Translational andrology and urology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11399049/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142296312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although SUI can occur after surgical treatment of benign prostatic hyperplasia, specifically transurethral prostate resection, laser enucleation of the prostate, and simple open prostatectomy, these therapeutic modalities play a much less significant role in the etiology of SUI. Artificial urethral sphincter (AUS) implantation is considered the standard treatment modality providing high success rates, including durable efficacy, and optimal patient satisfaction for moderate to severe urinary incontinence resulting mainly from radical prostatectomy. However, although complication rates are generally acceptably low, revision and/or explantation may be required due to mechanical failure and non-mechanical problems, specifically urethral atrophy/cuff deficient occlusion, infection, and cuff erosion. Several risk factors for AUS failure associated with a fragile, compromised urethra have been identified and these play a critical role in device cuff erosion and subsequent removal of the device. Among others, apparently the most impacting factors are irradiation, urethral stent placement, a previous AUS placement, and importantly presence of urethral stricture or prior urethroplasty. Generally, any clinical situation leading to a diseased urethra or lack of urethral integrity is associated with impaired local blood perfusion, and consequently lower success rates.
