INTRODUCTION: We sought to evaluate device outcomes in men who underwent primary artificial urinary sphincter (AUS) placement after failed male urethral sling (MUS). METHODS: We performed a retrospective chart review of 990 men who underwent an AUS procedure between 2003 and 2014. Of these, 540 were primary AUS placements, including 30 (5.5%) with a history of MUS. AUS revisions and explantations were compared between men stratified by the presence of prior sling...

Urinary incontinence is a widespread problem for women, with stress urinary incontinence (SUI) being the most common type. An updated review of PubMed literature using the following keywords was performed: stress urinary incontinence, women, midurethral slings, bulking agents, pubovaginal slings, retropubic suspension, postoperative complications, and treatment outcome. More recent publications, systematic reviews, and meta-analyses were given preference. The aging population will increase the demand for care of women with SUI...

INTRODUCTION: Although preoperative negative urine culture results and treatment of urinary tract infections are generally advised before artificial urinary sphincter (AUS) and penile prosthesis (PP) surgery to prevent device infection, limited evidence exists to support this practice. AIM: To evaluate the relation between preoperative urine culture results and the bacteriology of prosthetic device infections. METHODS: Men undergoing AUS and/or PP placement at a tertiary referral center from 2007 through 2015 were analyzed...

Urinary incontinence is a largely spread disfunction that affects more than 300 million people worldwide. At present, no technological solutions are able to restore continence in a minimally invasive and effective way. In this article the authors report the design, fabrication, and testing of a novel artificial endourethral urinary sphincter able to fully restore continence. The device can be inserted/retracted in a minimally invasive fashion without hospital admission, does not alter the body scheme and can be applied to both women and men...

Patients undergoing artificial urinary sphincter (AUS) placement often have complex medical and surgical histories, such as radical prostatectomy, endoscopic treatment of urethral strictures, previous AUS placement, and prior open urethral surgery. Urethral strictures at the bladder neck, membranous urethra, or site of a previous AUS erosion are problems that profoundly affect the timing and treatment success of AUS placement. Understanding the complexities and outcomes in this subset of patients is the only way to inform shared decision making about treatment of urinary incontinence...

INTRODUCTION: The most common cause of urinary incontinence in men after radical prostatectomy is intrinsic sphincter deficiency, which can affect long-term quality of life. The prevalence of stress urinary incontinence (SUI) after radical prostatectomy has been reported to be 2.5% to 90%. For patients with moderate to severe male SUI, the artificial urinary sphincter (AUS) is considered the gold standard in surgical treatment. AIM: To review the available literature on the development, patient selection, surgical technique, complications, and management of AUS for male SUI...

This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS im¬plant, provided by a private nonprofit HMO operating in Belo Horizonte, Brazil. On total, there were 91 AUS implants, with a median interval between radical prostatectomy and AUS implant of 3.6 years (IQR 1.9 to 5.5). The rate of AUS cumulative survival, after a median follow-up of 4...

This case report describes 2 cases of persistent urinary incontinence in the beginning of the learning curve of robot-assisted bladder neck implantation of an artificial urinary sphincter (RA-AUS) in men at risk for erosion due to neurological lesions. Among a series of 4 RA-AUS, 2 patients still experienced urinary incontinence after surgery. A complete urological workup was strictly normal and did not show any device malfunction. However, during an AUS revision in these two patients, exploration revealed that the cuff was not tight enough...

BACKGROUND: Androgen deprivation therapy (ADT) causes systemic tissue atrophy. It is unclear if this tissue atrophy adversely impacts artificial urinary sphincter (AUS) outcomes. We sought to evaluate the effect of ADT on adverse AUS outcomes. METHODS: We retrospectively identified 518 men undergoing primary AUS placement at our institution between 1998 and 2014. Rates of device explant for infection/erosion, mechanical failure, and urethral atrophy in men with >6 months of ADT use within 2 years prior to AUS placement were compared to ADT naive men...

Radiation-induced urethral stricture occurs most often due to radiation for prostate cancer. It is one of the most common side effects of radiotherapy. Stricture rates are lowest in patients undergoing external beam radiation therapy, occur more frequently in those who require brachytherapy and show highest stricture rates in patients receiving a combination of external beam radiation and brachytherapy. Strictures are mostly located at the bulbomembranous part of the urethra. Diagnostic work-up should include basic urologic work-up, ultrasound, uroflowmetric assessment, urethroscopy, retrograde urethrogram and voiding cystourethrography...

INTRODUCTION: Stress urinary incontinence (SUI) is a degradation of the quality of life factor in the consequences of radical prostatectomy. Artificial urinary sphincter (AUS) is the standard treatment. Screening and preoperative treatment of anastomotic strictures (AS) is an essential step for the success of the intervention. The objective of the study was to assess the impact of AS on the results of AUA. METHODS: We retrospectively studied 147 AUS settlements from 2005 to 2013 in the urology department of the Centre Hospitalier Lyon by three operators...

OBJECTIVE: To evaluate whether filling phase urodynamic parameters can predict the success of the artificial urinary sphincter (AUS) in treating post-prostatectomy incontinence (PPI). MATERIALS AND METHODS: We reviewed the pre-AUS urodynamics of 99 patients with PPI at two tertiary referral centers. We documented the peak DO pressure (Pdet ), capacity, and compliance (C). We defined success as patient-reported continence or only using one safety pad. Patients' perception of improvement was assessed using the PGI-I score...

OBJECTIVE: To determine if oral corticosteroid use is associated with an increased risk of artificial urinary sphincter (AUS)-related reoperation. MATERIALS AND METHODS: Administrative data from Ontario were used to conduct a retrospective cohort study. Men >65 years of age who underwent implantation of an AUS between 2002 and 2013 were included. Prescriptions for oral corticosteroids were identified, and men were considered exposed from the date the prescription was dispensed to 180 days after the expected end of the prescription...

Urinary incontinence, often related to sphincter damage, is found in male patients, leading to a miserable quality of life and to huge costs for the healthcare system. The most effective surgical solution currently considered for men is the artificial urinary sphincter that exerts a pressure field on the urethra, occluding the duct. The evaluation of this device is currently based on clinical and surgical competences. The artificial sphincter design and mechanical action can be investigated by a biomechanical model of the urethra under occlusion, evaluating the interaction between tissues and prosthesis...
