Urinary incontinence and erectile dysfunction are relatively common conditions in the aging male population. Surgical interventions for urinary incontinence include placement of an artificial urinary sphincter (AUS), perineal sling, or sacral nerve stimulator and injections of periurethral bulking agents. Erectile dysfunction can be treated surgically with placement of a penile prosthesis. The complications of these devices can be broadly categorized as device component malposition, malfunction, and infection...

BACKGROUND: Pelvic radiation is a known risk factor for the development and progression of erectile dysfunction. When medical therapy fails, the 3-piece inflatable penile prosthesis (IPP) can offer patients a definitive treatment option. Because of radiation-induced vascular changes and tissue fibrosis, a careful surgical approach is necessary to avoid intraoperative complications and attain successful outcomes. Despite its widespread use in prostate cancer treatment, there are no contemporary studies examining the effects that pelvic radiation can have on 3-piece IPP placement and device survival...

OBJECTIVES: To report the prevalence of low serum testosterone (LST) in men undergoing AUS placement at a single high-volume institution METHODS: We retrospectively reviewed all men undergoing AUS procedures by a single surgeon from January 2015 to January 2018 to identify men with pretreatment total serum testosterone levels. LST was defined as less than 280 ng/dL. Patients with only post-treatment testosterone levels were excluded. Demographic characteristics and clinical outcomes were compared between men with and without LST...

INTRODUCTION: Male stress urinary incontinence (SUI) after radical prostatectomy (RP) is common. The surgical standard of care traditionally has been placement of an artificial urinary sphincter (AUS) but since its introduction the transobturator male sling has been shown to have particular unique advantages. Our aim was to assess outcomes of a consecutive series of suburethral sling insertions in men presenting with all degrees of post RP SUI. MATERIALS AND METHODS: A consecutive cohort of men undergoing AdVance sling insertion following RP were studied...

AIMS: To report on the long-term outcomes of hydraulic artificial urethral sphincter (HAUS) placement for the correction of urethral sphincter mechanism incompetence (USMI) in New Zealand dogs. METHODS: Retrospective data were obtained from cases of dogs which had a HAUS placed after failed medical and/or surgical management of USMI between August 2012 and November 2016. Owner assessment of urinary incontinence was evaluated by an online survey in May 2017 using a visual analogue scale (0 being normal, 100 being severely affected) for the frequency, volume and severity of any straining to urinate, immediately prior to the placement of the HAUS and at the time of the survey...

REVIEW
Javier C Angulo, Reynaldo G Gómez, Dmitriy Nikolavsky
PURPOSE OF REVIEW: Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries...

BACKGROUND: Up to 50% of patients receiving an artificial urinary sphincter (AUS) require surgical revision after initial placement. However, the literature is heterogeneous regarding the leading causes of AUS failure and appropriate surgical management. OBJECTIVE: To inform a revision approach by tabulating the causes of AUS failure, assessing AUS component survival, and examining the single-component revision efficacy. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively reviewed 168 patients receiving AUS placements carried out by a single surgeon from 2008 to 2016 at a high-volume academic institution...

AIM: To identify the costs of replacing an entire malfunctioning AUS device versus an individual component at the time of device malfunction. METHODS: Decision analysis was performed by analyzing the costs associated with revising a malfunctioning artificial urinary sphincter using one of two techniques: either individual or entire device replacement. Costs were determined by including actual institutional costs. Model assumptions were based on a summary of published literature and were created based on a time horizon of 0-5 years since the original, primary AUS was placed, and models were created for malfunction of each individual component...

BACKGROUND: Stress urinary incontinence (SUI) is a frequent adverse effect for men undergoing prostate surgery. A large proportion (around 8% after radical prostatectomy and 2% after transurethral resection of prostate (TURP)) are left with severe disabling incontinence which adversely effects their quality of life and many are reliant on containment measures such as pads (27% and 6% respectively). Surgery is currently the only option for active management of the problem. The overwhelming majority of surgeries for persistent bothersome SUI involve artificial urinary sphincter (AUS) insertion...

BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions...

Artificial urinary sphincters and penile corpus cavernosum prostheses are effective for patients who are not adequately treated by conservative treatment or pharmacotherapy. Both of these devices show good results concerning functional outcome if used within the correct patient selection. Penile prostheses are meant to be the last line of treatment for severe erectile dysfunction after failure of conventional treatment. Artificial urinary sphincters are the treatment of choice for severe urinary stress incontinence...

Case Hypothesis: Surgical removal is the standard treatment for artificial sphincter extrusion. However in some specific situations is possible to maintain the prosthesis with good results. CASE REPORT: We report a 60 years old patient presenting sphincter pump extrusion one month after artificial urinary sphincter (AUS) AMS 800™ placement for treating post-radical prostatectomy urinary incontinence (PRPUI). He also had a penile prosthesis implant one year before that was replaced in the same surgery the sphincter was implanted...

Stress urinary incontinence in women is a common problem in Germany, with approx. 5 million women suffering from incontinence symptoms. These numbers are increasing, due to demographic changes; the suspected numbers are even higher. Prior to treatment, an extended diagnostic approach - including urodynamics and cystoscopy when necessary - is essential for optimal treatment selection.Primary treatment should be conservative, with pelvic floor training as an essential part of a multi-modal treatment concept. If conservative treatment fails, surgery is necessary and an increasing number of women are being treated with sub-urethral slings...

INTRODUCTION: We aimed to present three novel remotely controlled hydromechanical artificial urinary sphincters (AUSs) and report their in-vitro and ex-vivo results. METHODS: We successively developed three distinct hydromechanical AUSs on the basis of the existing AMS800™ device by incorporating an electronic pump. No changes were made to the cuff and balloon. The AUS#1 was designed as an electromagnetically controlled device. The AUS#2 and AUS#3 were conceived as Bluetooth 2...

Background: To determine which preoperative factors drive patient-reported quality of life (QoL) after artificial urinary sphincter (AUS) implantation. Methods: Men receiving AUS after prostate cancer treatment were identified from a prospectively collected dataset. Preoperative factors were recorded during the initial incontinence consultation. Patients underwent urodynamic testing (UDS) preoperatively at surgeon discretion. Patients were surveyed by telephone postoperatively and given the EPIC Urinary Domain (EPIC-UD) and Urinary Distress Inventory (UDI-6) questionnaires...
