“…As many patients have urologic conditions that progress over time, and consequently require reassessment if their care is to be optimized, serial NIRS bladder monitoring in parallel with synchronized uroflow data from a paired wireless scale is another valid clinical role for NIRS. 32 Studies indicate that periodic hospital assessment fails to capture true voiding behavior as realistically as multiple measurements collected at home, because serial measures document individual voiding variability and better reflect the status of a patient's voiding dysfunction; 33 Consequently, home-based monitoring which is able to provide serial urinary flow measurements in parallel with NIRS-derived physiologic parameters indicative of bladder health should be of benefit for patients and their health care providers. With appropriate cloud-storage and data transfer processes this will enable urologists to make better-informed decisions regarding patient care.…”

Background: Spinal cord injury (SCI) compromises bladder function, including the ability to sense the need to void. Overdistension leads to involuntary leakage and endangers health through upper renal tract pressure damage and autonomic dysreflexia. A monitor warning the bladder is full will allow optimal use of manual expression or intermittent catheterization. Methods: The wearable interface is a silicone sheet worn over the bladder, which incorporates a grid of 4 near-infrared LED transmitters with 3 wavelengths (2 at 950 nm for water detection and 2 of 760 and 850 nm for conventional monitoring of O2Hb and HHb). The system has 8 continuous-wave measurement channels and monitors at 2 different vertical levels to detect variation in bladder fullness; IOD’s of 30 and 40mm provide information at 2 depths. Associations between optical densities during bladder emptying and then during natural filling were compared. Results: Data from 4 male and one female subject were analyzed. The optical densities recorded at the lower vertical locations showed positive correlation with the voiding rate (ratio of scale signal), and O2Hb and HHb concentration changes at higher vertical locations revealed muscle activation prior to voiding. Discussion: This pilot study provides proof of the feasibility of using a 950nm wavelength incorporated into a wearable NIRS bladder monitoring system to transcutaneously and non-invasively detect changes in bladder volume in real-time. Conclusions: Ongoing research is warranted to further evaluate the system as the bladder fills naturally; and establish the clinical value of the data obtained to patients living with spinal cord injury

“…Stothers and Macnab [ 13 ] employed an NIRS device, PortaMon (Artinis BV, Leiden, The Netherlands; 83.8 × 49.2 × 17.2 mm) to measure uroflow data, including BV. Their study results were limited to the total of six voiding episodes of only two human subjects.…”

“…In the research field, various bladder monitoring methods have been studied based on sensor and wearable technologies using diverse types of data including ultrasound (US) [ 7 , 8 , 9 , 10 , 11 , 12 ], near-IR spectroscopy (NIRS) [ 13 , 14 , 15 ], and bioimpedance (BI) [ 16 , 17 , 18 , 19 ]. Despite these methods having expanded bladder monitoring in a portable and cost-effective manner with comparable accuracies, they appear to have limitations when applied to the long-term and continuous monitoring of pediatric patients during sleep, such as large form factors (e.g., MoUsE [ 8 ], 18.4 cm × 12.3 cm × 3.3 cm), compared to young children’s body sizes (e.g., median height of 102.5 cm for 4-year-old children [ 20 ]).…”

Nocturnal enuresis (NE) is involuntary bedwetting during sleep, typically appearing in young children. Despite the potential benefits of the long-term home monitoring of NE patients for research and treatment enhancement, this area remains underexplored. To address this, we propose NEcare, an in-home monitoring system that utilizes wearable devices and machine learning techniques. NEcare collects sensor data from an electrocardiogram, body impedance (BI), a three-axis accelerometer, and a three-axis gyroscope to examine bladder volume (BV), heart rate (HR), and periodic limb movements in sleep (PLMS). Additionally, it analyzes the collected NE patient data and supports NE moment estimation using heuristic rules and deep learning techniques. To demonstrate the feasibility of in-home monitoring for NE patients using our wearable system, we used our datasets from 30 in-hospital patients and 4 in-home patients. The results show that NEcare captures expected trends associated with NE occurrences, including BV increase, HR increase, and PLMS appearance. In addition, we studied the machine learning-based NE moment estimation, which could help relieve the burdens of NE patients and their families. Finally, we address the limitations and outline future research directions for the development of wearable systems for NE patients
