Background/aim: The male sling operation and artificial urinary sphincter implantation are common methods for treating urinary incontinence. However, there are some drawbacks to these methods such as infection, urethral erosion, pain, inefficiency, and the technical difficulty of the operations. Here we describe a new device we have named the Turkish Continence Device (TCD) which has advantages over these other methods. The aim of this study was perform experiments with the TCD prototype in vivo and ex vivo to determine efficiency, convenience of implantation, and negative effects. Materials and methods: We implanted the prototype device in male goats and sheep, compressing the posterior urethra, and then fixed it by sutures on the lateral sides of the cavernosal bodies, bilaterally. Then we recorded urodynamic findings and performed urinary imaging. Additionally we measured urethral closure pressure ex vivo. Results: The balloon volume for efficient urethral closure pressure using the new device was under 1 mL. It compressed the urethra towards the corpus cavernosum perfectly, because the wings of the prototype device are fixed near the tunica of the cavernosal bodies on each side. Conclusion: A smaller device with smaller arms/wings would be efficient for obtaining enough pressure on the urethra. Additionally, the technique for implanting the device is very simple and would likely be learned quickly.

Recent technology advances have led urology to become one of the leading specialities to utilise novel electronic systems to manage urological ailments. Contemporary bladder management strategies such as urinary catheters can provide a solution but leave the user mentally and physically debilitated. The unique properties of modern electronic devices, i.e., flexibility, stretchability, and biocompatibility, have allowed a plethora of new technologies to emerge. Many novel electronic device solutions in urology have been developed for treating impaired bladder disorders. These disorders include overactive bladder (OAB), underactive bladder (UAB) and other-urinary-affecting disorders (OUAD). This paper reviews common causes and conservative treatment strategies for OAB, UAB and OUAD, discussing the challenges and drawbacks of such treatments. Subsequently, this paper gives insight into clinically approved and research-based electronic advances in urology. Advances in this area cover bladder-stimulation and -monitoring devices, robot-assistive surgery, and bladder and sphincter prosthesis. This study aims to introduce the latest advances in electronic solutions for urology, comparing their advantages and disadvantages, and concluding with open problems for future urological device solutions.

“…However, this may clearly not be regarded as the only factor explaining this relatively limited use given that there is a similar lack of high level of evidence studies supporting the use of male AUS (only one underpowered poorly designed RCT) [50,51]. [52][53][54]. The main advantages of electromechanical AUS are that they would be remotely controlled, allowing the labia majora pump to be omitted, and that they may allow to adjustment the pressure exerted on the urethra, hypothetically reducing the risk of erosion and revision due to damage to the bladder neck tissue.…”

Current Use of the Artificial Urinary Sphincter in Adult Females

Purpose of Review The aim of the present report was to review the recent evidences regarding the use of artificial urinary sphincter (AUS) in adult females. Recent Findings While the excellent functional outcomes of AUS in female patients with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD) have been reported for decades, its use has remained confidential in most countries likely due to its challenging implantation and inherent morbidity. Over the past few years, laparoscopic and, more recently, robotic techniques of AUS implantation in female patients have been described with promising perioperative outcomes. As a result, the use of AUS has increased in several countries. The indications are mostly recurrent or persistent SUI after previous antiincontinence procedures and neurogenic SUI. Owing to its unique potential to restore continence while maintaining low outlet resistance during the voiding phase, AUS may be of special interest in female patients with detrusor underactivity. High level of evidence data from trials which are underway, along with developments in robotic surgery and technological refinements of the device, may well, almost 50 years after its introduction, give to the AUS its momentum as a major contributor in the female SUI armamentarium. Summary While the use of AUS in female patients has been restricted to some countries and a few high-volume centers, it has started spreading again over the past few years, thanks to the rise of minimally invasive approaches which facilitate its implantation, and this is yielding promising outcomes.
