“…Novel detection and treatment modalities are under development to enable real-time sensation of bladder filling for patients who are unable to perceive afferent sensory input in suprasacral SCI [ 17 , 44 ]. Nasrabadi and colleagues have recently described in detail the current status of wearable devices for urodynamic monitoring, which encompass methods such as ultrasound, near-infrared spectroscopy, body impedance, and implantable sensors [ 45 ]. Capsular intravesical devices are also under development to address concerns regarding treatment invasiveness, device migration, and erosion due to corrosive exposure to urine [ 46 ].…”

“…Capsular intravesical devices are also under development to address concerns regarding treatment invasiveness, device migration, and erosion due to corrosive exposure to urine [ 46 ]. Preclinical studies to date have been trending towards wearable and non-invasive devices, but inherent challenges persist in portability and device alignment with varying body features [ 45 ]. The unique characteristics of each SCI insult has spurred progress towards the development of wearable and invasive technologies which may be tailored to patient-specific needs [ 45 ].…”

One of the well reported but difficult to manage symptoms of spinal cord injury (SCI) is neurogenic lower urinary tract dysfunction (NLUTD). The type of NLUTD is variable based on location and extent of injury. SCI affects more males and NLUTD is especially debilitating for men with incomplete injury. This review summarizes the anatomical basis of NLUTD in SCI and discusses current diagnostic and management strategies that are being utilized clinically. The last two sections address new innovations and emerging discoveries with the goal of increasing scientific interest in improving treatment options for people with SCI. Areas warranting further investigation are pinpointed to address current gaps in knowledge and/or appropriate technology.

Purpose of Review Near infrared spectroscopy (NIRS) is a non-invasive optical technique that uses near infrared light to detect the oxygenation status and hemodynamics of various organs. This article reviews the use of NIRS for the non-invasive assessment of lower urinary tract dysfunction (LUTD). Applications include assessment of bladder outlet obstruction, overactive and underactive bladder, neurogenic LUTD, pediatric LUTD, interstitial cystitis/bladder pain syndrome, and pelvic floor dysfunction. In addition, the article describes how NIRS is elucidating more about the brain-bladder connection. Technological advancements enabling these applications are also discussed. Recent Findings While evidence exists for the application of NIRS throughout a wide range of LUTD, most of these studies are limited by small sample sizes without matched controls. Investigators have experienced problems with reproducibility and motion artifacts contaminating the data. The literature is also becoming dated with use of older technology. Summary NIRS holds potential for the non-invasive acquisition of urodynamic information over time scales and activities not previously accessible, but it is not yet ready for use in routine clinical practice. Advances in wearable technology will address some of the current limitations of NIRS, but to realize its full potential, larger scale validation studies will be required. Moreover, multidisciplinary collaboration between clinicians, scientists, engineers, and patient advocates will be critical to further optimize these systems.

“…However, due to the many adverse side-effects, assistive electronic devices better suited to manage urological conditions are being explored. Several reviews have investigated the bladder-monitoring systems [41,42]. However, the recent development of flexible electronics and biocompatible materials provides a range of novel electronic solutions such as bladder-stimulation devices [43][44][45][46], bladder actuators [47][48][49] and artificial prosthetic devices [50][51][52] that can assist in emptying the bladder.…”

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.
