INTRODUCTION
Nephrology, the branch of medicine concerned with diagnosing and treating kidney diseases, has witnessed significant advancements in recent years.Among these developments, portable and continuous monitoring devices have emerged as valuable tools, offering numerous benefits for patients and healthcare providers.These devices enable real-time assessment of various physiological parameters, facilitating early detection of complications, personalized treatment approaches, and improved patient outcomes (Smith et al., 2021).Moreover, they enhance patient autonomy and quality of life by allowing remote monitoring and home-based therapy (Johnson et al., 2020).This narrative review explores the current state of portable and continuous monitoring technologies in nephrology, focusing on their applications, clinical outcomes, and impact on patient quality of life.METHODOLOGY A thorough literature search was conducted using relevant databases, including Scopus, PubMed, and ScienceDirect, to provide a comprehensive overview of portable and continuous monitoring devices in nephrology.The search terms included combinations of "nephrology," "portable devices," "continuous monitoring," "dialysis," "remote monitoring," "glucose monitoring," "glomerular filtration rate," "bioimpedance spectroscopy," and "ambulatory blood pressure monitoring."The articles were screened for relevance, and those published within the last five years were prioritized to ensure the most up-to-date information.The selected articles were critically appraised for their methodological quality and the strength of their findings.
The results were synthesized and organized into subtopics, presenting the critical aspects of portable and continuous monitoring devices in nephrology.

Improved Dialysis Monitoring
Hemodialysis, a standard treatment for end-stage kidney disease, requires careful monitoring to ensure optimal outcomes.Portable and continuous monitoring devices have revolutionized dialysis monitoring, allowing for real-time assessment of various parameters.
Online monitoring systems, such as the Crit-Line Monitor (CLM), enable continuous hematocrit, oxygen saturation, and blood volume measurement during hemodialysis sessions (Rao et al., 2019).These devices provide valuable insights into the patient's fluid status and help prevent intradialytic hypotension, a common complication associated with increased

Remote Monitoring in Peritoneal Dialysis
Peritoneal dialysis (PD) is a home-based therapy that requires patient self-management and regular monitoring.Remote monitoring (RM) technologies have emerged as a valuable tool in PD, enabling healthcare providers to closely monitor patients' treatment progress and identify potential complications early (Sanabria et al., 2019).RM in automated peritoneal dialysis (APD) has been shown to reduce emergency visits and disease-specific hospitalizations, particularly in patients with higher comorbidity scores (Bezerra et al., 2021).Future research should focus on evaluating the long-term cost-effectiveness of portable and continuous monitoring devices in nephrology and their impact on patient-reported outcomes and quality of life.The development of standardized protocols for using these devices and interpreting their data is also essential to ensure consistent and reliable results across different healthcare settings (Cao et al., 2020).Moreover, integrating these technologies with telemedicine and remote consultation services may further enhance their potential to improve access to care and optimize resource utilization in nephrology (Galindo et al., 2020).

CONCLUSION
In conclusion, portable and continuous monitoring devices have emerged as a transformative force in nephrology, offering significant benefits for patients and healthcare providers.These technologies enable real-time assessment of various physiological parameters, facilitating early detection of complications, personalized treatment approaches, and improved patient outcomes.The findings of this narrative review highlight the potential of these devices to enhance clinical decision-making, optimize treatment strategies, and improve patient quality of life across various aspects of nephrology care, including dialysis monitoring, glucose management, glomerular filtration rate assessment, fluid status monitoring, and hypertension management.
As the field of nephrology continues to evolve, the widespread adoption and integration of portable and continuous monitoring devices into standard care protocols can potentially revolutionize the management of kidney diseases.However, addressing the challenges associated with their implementation, including financial constraints, training requirements, and data interpretation, is crucial to realizing their full potential.Future research should focus on evaluating the long-term cost-effectiveness of these technologies, developing standardized protocols for their use, and exploring their integration with telemedicine services to enhance access to care and optimize resource utilization.
By harnessing the power of portable and continuous monitoring devices, nephrologists can usher in a new era of personalized, precision medicine, where treatment decisions are guided by real-time data and tailored to each patient's unique needs.The transformative potential of these technologies in improving patient outcomes, enhancing quality of life, and optimizing resource utilization in nephrology cannot be overstated.As the field continues to evolve, healthcare providers, researchers, and policymakers must work together to ensure the responsible and effective integration of portable and continuous monitoring devices into nephrology care, ultimately benefiting patients worldwide.
morbidity and mortality (Sars et al., 2020).A study by Leung et al. (2020) demonstrated that using CLM significantly reduced intradialytic hypotensive episodes and improved patient outcomes.Furthermore, real-time monitoring of dialysis adequacy, including urea removal and sodium balance, allows for timely adjustments to the dialysis prescription, ensuring optimal treatment efficacy (Ding et al., 2021).

A
systematic review by Cao et al. (2020) found that RM in PD was associated with improved patient satisfaction, enhanced perceived safety of home-based therapy, and reduced healthcare costs.Integrating RM technologies in PD can improve patient outcomes, increase treatment adherence, and optimize resource utilization in nephrology care.Continuous Glucose Monitoring Diabetes is a leading cause of end-stage kidney disease, and glycemic control is crucial for preventing complications and improving outcomes in this patient population.Continuous glucose monitoring (CGM) devices have emerged as a valuable tool for managing diabetes in patients with kidney disease (Chadban et al., 2020).CGM provides a more accurate and dynamic assessment of glycemic control compared to traditional methods like HbA1c, which may be unreliable in chronic kidney disease (Jiang et al., 2021).Ramirez et al. (2019) found that CGM use in patients with diabetes and end-stage kidney disease improved glycemic control, reduced hypoglycemic events, and enhanced patient satisfaction.CGM also facilitates the detection of glycemic variability associated with increased cardiovascular risk in this population (Galindo et al., 2020).The integration of CGM in managing diabetes and kidney disease has the potential to optimize treatment strategies, reduce complications, and improve patient outcomes.Real-Time Glomerular Filtration Rate Monitoring Glomerular filtration rate (GFR) is a critical indicator of kidney function, and its accurate assessment is essential for diagnosing and monitoring kidney diseases.Traditional methods of GFR estimation, such as serum creatinine-based equations, have limitations and may not reflect real-time changes in kidney function (Yong et al., 2020).Technological advances have led to the development of portable and continuous GFR monitoring devices, which use transdermal sensors and fluorescent markers to provide real-time measurements (Sedehi et al., 2019).These devices offer several advantages, including early detection of acute kidney injury, dynamic assessment of kidney function, and personalized treatment approaches (Nkuipou-Kenfack et al., 2021).A pilot study by Hennings et al. (2022) demonstrated the feasibility and accuracy of continuous GFR monitoring in critically ill patients, highlighting its potential to guide therapeutic interventions and improve outcomes.The widespread adoption of real-time GFR monitoring devices has the potential to revolutionize the diagnosis and management of kidney diseases.Wearable Bioimpedance Spectroscopy Fluid management is critical to nephrology care, particularly in dialysis patients.Wearable bioimpedance spectroscopy (BIS) devices have emerged as a promising tool for continuous fluid status monitoring in hemodialysis patients (Tabinor et al., 2020).These devices use electrical impedance measurements to assess fluid distribution and composition in the body, providing valuable insights into hydration status and fluid overload (Vega et al., 2021).A study by Zhang et al. (2019) found that wearable BIS devices effectively detect fluid overload and guide fluid management in hemodialysis patients, leading to improved hemodynamic stability and reduced hospitalizations.Moreover, the continuous monitoring capabilities of wearable BIS devices offer the potential for personalized dialysis prescriptions and enhanced quality of life (Vilar et al., 2019).The integration of wearable BIS technology in nephrology care has the potential to optimize fluid management, reduce complications, and enhance patient outcomes.Ambulatory Blood Pressure Monitoring Hypertension is a common comorbidity in patients with chronic kidney disease (CKD) and a significant risk factor for cardiovascular events and kidney disease progression.Ambulatory blood pressure monitoring (ABPM) has emerged as a valuable tool for assessing blood pressure patterns and guiding hypertension management in CKD patients (Drawz et al., 2020).ABPM provides a comprehensive assessment of blood pressure variability, including nocturnal variations, which have been associated with adverse cardiovascular and kidney outcomes (Burnier et al., 2019).A meta-analysis by Yang et al. (2021) found that ABPM-guided hypertension management in CKD patients improved blood pressure control, reduced cardiovascular events, and slower kidney disease progression compared to office-based blood pressure measurements.Moreover, ABPM can help identify masked hypertension, a condition characterized by normal office blood pressure but elevated ambulatory readings, which is prevalent in CKD patients and associated with increased cardiovascular risk (Minutolo et al., 2019).The incorporation of ABPM in the routine management of hypertension in CKD patients has the potential to optimize treatment strategies, improve cardiovascular outcomes, and slow the progression of kidney disease.DISCUSSION The advent of portable and continuous monitoring devices has transformed the landscape of nephrology care, offering numerous benefits for patients and healthcare providers.These technologies enable real-time assessment of various physiological parameters, facilitating early detection of complications, personalized treatment approaches, and improved patient outcomes.Integrating these devices into clinical practice can revolutionize kidney disease management, from early diagnosis to the optimization of treatment strategies.The findings of this narrative review highlight the significant impact of portable and continuous monitoring devices on various aspects of nephrology care.In dialysis, real-time monitoring of fluid status, dialysis adequacy, and hemodynamic stability has been shown to reduce complications, improve patient outcomes, and enhance quality of life (Rao et al., 2019; Sars et al., 2020).Remote monitoring technologies in peritoneal dialysis have demonstrated the potential to reduce healthcare utilization, increase patient satisfaction, and optimize homebased therapy (Sanabria et al., 2019; Bezerra et al., 2021).Moreover, continuous glucose monitoring in patients with diabetes and kidney disease has improved glycemic control, reduced hypoglycemic events, and enhanced patient satisfaction (Ramirez et al., 2019).The development of real-time glomerular filtration rate monitoring devices offers the potential for early detection of acute kidney injury and personalized treatment approaches (Sedehi et al., 2019; Nkuipou-Kenfack et al., 2021).Wearable bioimpedance spectroscopy devices have shown promise in optimizing fluid management and reducing complications in hemodialysis patients (Tabinor et al., 2020; Zhang et al., 2019).Finally, ambulatory blood pressure monitoring has emerged as a valuable tool for assessing blood pressure patterns and guiding hypertension management in chronic kidney disease patients, leading to improved cardiovascular outcomes and slower kidney disease progression (Drawz et al., 2020; Yang et al., 2021).Despite the numerous benefits of portable and continuous monitoring devices in nephrology, several challenges and limitations must be addressed.The widespread adoption of these technologies requires substantial financial investments, training of healthcare professionals, and patient education (Smith et al., 2021).Moreover, integrating these devices into existing healthcare systems and workflows may pose logistical challenges (Johnson et al., 2020).Interpreting the vast amounts of data generated by these devices also requires specialized expertise and the development of robust data analytics tools (Ding et al., 2021).
