Scrotal and penile edema is a noninfectious complication of peritoneal dialysis (PD). A tear in the Spigelian fascia is occasionally recognized as a Spigelian hernia. However, there is no documented evidence that this is a contributing factor for scrotal edema in individuals undergoing PD. We encountered a case of scrotal edema in a patient undergoing PD due to bilateral metachronous tears in the Spigelian fascia, which was successfully treated through surgical repair. A 20-year-old man with end-stage kidney disease due to Alport syndrome underwent PD. Eight months after induction of PD, he heard a rupture sound in the left inguinal region after coughing and developed genital edema. A computed tomography scan showed a tear in the left Spigelian fascia. Surgical repair was successful and there was no recurrence after PD was resumed. Seven months after surgery, he heard a rupture sound in the right inguinal region after coughing and developed genital edema. A computed tomography scan showed a tear in the right Spigelian fascia. Surgical repair was successful and there has been no recurrence since. It is important to recognize that the development of scrotal edema in a patient undergoing PD may be indicative of a tear in the Spigelian fascia.

Automation has allowed clinicians to program PD treatment parameters, all while obtaining extensive individual treatment data. This data populates in a centralized online platform shortly after PD treatment completion. Individual treatment data available to providers includes patients' vital signs, alarms, bypasses, prescribed PD treatment, actual treatment length, individual cycle fill volumes, ultrafiltration volumes, as well as fill, dwell, and drain times. However, there is no guidance about how often or if this data should be assessed by the clinical team members. We set out to determine current practice patterns by surveying members of the home dialysis team managing PD patients across the United States and Canada. A total of 127 providers completed the survey. While 91% of respondents reported having access to a remote monitoring platform, only 31% reported having a standardized protocol for data monitoring. Rating their perceived importance of having a standard protocol for remote data monitoring, on a scale of 0 (not important at all) to 10 (extremely important), the average response was 8 (physicians 7; nurses 9). Most nurses reported reviewing the data multiple times per week, whereas most physicians reported viewing the data only during regular/monthly visits. Although most of the providers who responded have access to remote monitoring data and feel that regular review is important, the degree of its utilization is variable, and the way in which the information is used is not commonly protocolized. Working to standardize data interpretation, testing algorithms, and educating providers to help process and present the data are important next steps.

Background: Home dialysis therapies have limited uptake in most regions despite recognized benefits such as increasing patients' independence, and several domains of quality of life with cost savings in some systems.

Objective: To perform a scoping review of published literature to identify tools and guides used in systematically screening and assessing patient suitability for home dialysis. A secondary objective was to explore barriers and enablers associated with the home dialysis assessment process. It is important to identify gaps in current research to pose pertinent questions for future work in the field.

Design: Online databases Embase, Medline (Ovid), and CINAHL were used to identify articles published between January 2007 to May 2023. A total of 23 peer-reviewed primary and secondary studies that investigated screening or selection for patients > 18 years old with kidney failure for home dialysis met the study inclusion criteria.

Results: The studies consisted of secondary studies (n = 10), observational studies (n = 8), and survey-based studies (n = 5). The major themes identified that influence patient screening and assessment for home dialysis candidacy included: screening tools and guidelines (n = 8), relative contraindications (n = 4), patient or program education (n = 9), and socioeconomic factors (n = 2).

Limitations: Consistent with the scoping review methodology, the methodological quality of included studies was not assessed. The possible omission of evidence in languages other than English is a limitation.

Conclusion: This scoping review identified tools and factors that potentially guide the assessment process for home dialysis candidacy. Patient screening and assessment for home dialysis requires a comprehensive evaluation of clinical, psychosocial, and logistical factors. Further research is required to validate and refine existing tools to establish standardized patient screening criteria and evaluation processes. Up-to-date training and education for healthcare providers and patients are needed to improve the utilization of home dialysis and ensure optimal outcomes.

Background: Variation in residual volume between peritoneal dialysis dwells creates uncertainty in ultrafiltration determination, dialysis efficiency, and poses a risk of overfill if the residual volume is large. Measuring the dilution of a marker molecule during fluid fill offers a convenient approach, however, estimation accuracy depends on the choice of dilution marker. We here evaluate the feasibility of creatinine and urea as dilution markers compared to albumin-based residual volumes and three-pore model estimations.

Method: This clinical, retrospective analysis comprises 56 residual volume estimations from 20 individuals, based on the dilution of pre-fill dialysate creatinine, urea and albumin concentrations during the dialysis fluid fill phase. Outcomes were compared individually. Bias induced by ultrafiltration, marker molecule mass-transfer and influence of fluid glucose contents was quantified using the three-pore model. Linear regression established conversion factors enabling conversion between the various marker molecules.

Results: Creatinine-based calculations overestimated residual volumes by 115 mL (IQR 89-149) in 1.5% dwells and 252 mL (IQR 179-313) in 4.25% glucose dwells. In hypertonic dwells, ultrafiltration was 52 mL (IQR 38-66), while intraperitoneal creatinine mass increased by 67% during fluid fill, being the leading cause of overestimation. Albumin-based volumes conformed strongly with three-pore model estimates. Correction factors effectively enabled marker molecule interchangeability.

Conclusions: Mass-transfer of low molecular weight marker molecules is associated with residual volume overestimation. However, by applying correction factors, creatinine and urea dilution can still provide reasonable estimates, particularly when the purpose is to exclude the presence of a very large residual volume.

Peritoneal dialysis (PD) is a well-established modality for kidney replacement therapy (KRT) globally, offering benefits such as better preservation of residual kidney function, improved quality of life, and reduced resource requirements. Despite these advantages, the global utilization of PD remains suboptimal, particularly in South Asia (SA), where a significant gap in PD delivery exists. This study aims to uncover the perceived barriers hindering PD utilization among nephrologists in SA. This is a cross-sectional survey involving 732 nephrologists from SA region. . The majority of respondents (44.7%) reported initiating less than six PD cases annually, reflecting low PD utilization. Cost and financial reimbursement policies emerged as major barriers, with 44.3% considering PD more expensive than haemodialysis (HD). Accessibility, negative attitudes toward PD, and fear of complications were identified as critical factors influencing PD adoption. The study also highlighted variations in PD costs among SA countries, emphasizing the need for tailored health economic strategies. This analysis provides insights into the multifaceted challenges faced by SA nephrologists in promoting PD and underscores the importance of targeted interventions.

Peritoneal dialysis utilisation in Indonesia decreased yearly from 6.6% in 2014 to 1.6% in 2018. Various efforts have been made by the government and the Indonesian Nephrologist Organization (PERNEFRI) through education and regulation to optimise the use of peritoneal dialysis, but have yet to succeed. The simplicity of automated peritoneal dialysis (APD) made it worth considering as another solution to optimise peritoneal dialysis in Indonesia. Several advantages are offered by using APD, such as providing more time for activities compared to continuous ambulatory peritoneal dialysis, cheaper cost than haemodialysis and allowing remote monitoring. The advantages of APD make it a promising kidney replacement therapy (KRT) modality for developing countries like Indonesia, but the application is scarce. Some of the challenges in implementing APD in Indonesia include APD machines and fluids that are not available in the Indonesian market; the price of machines and fluids is still high; health workers are not familiar with APD; patients and their families not knowing APD as one of KRT; and APD machines distribution in archipelagic country is challenging.
