Background: Catheter malfunction is a common complication of peritoneal dialysis (PD). This study aimed to retrospectively analyze the risk factors and management of catheter malfunction in urgent-start PD.Methods: Patients who underwent urgent-start PD were divided into catheter-malfunction and control groups. Baseline demographic and laboratory data of the two groups were compared, and the risk factors for catheter malfunction were analyzed. Primary outcome measure was catheter survival, and the secondary outcomes were surgical complications and malfunction treatment.Results: Total of 700 patients was analyzed, among whom 143 (20.4%) experienced catheter malfunctions, specifically catheter migration (96, 67.1%), omental wrapping (36, 25.2%), and migration plus omental wrapping (11, 7.7%). Catheter survival time in the malfunction group (202.5 ± 479.4 days) was significantly shorter than that in the control group (1295.3 ± 637.0 days) (P < 0.001). Multivariate analysis revealed higher body mass index [hazard ratio (HR), 1.061; 95% confidence intervals (CI), 1.010–1.115; P = 0.018], lower surgeon count (HR, 1.083; 95% CI, 1.032–1.136; P = 0.001), and higher serum potassium (HR, 1.231; 95% CI, 1.041–1.494; P = 0.036) as independent risk factors for catheter malfunction, while older age (HR, 0.976, 95% CI, 0.962–0.991; P = 0.002) and colonic dialysis (HR, 0.384; 95% CI, 0.254–0.581; P < 0.001) as protective factors. Further subgroup analysis revealed a shorter catheter survival time in patients with younger age ( ≤ 40 years), higher serum potassium levels (≥5 mmol/L), while a longer catheter survival time in patients with colonic dialysis. PD tube and subcutaneous tunnel preservation was successful in 41 out of 44 patients with omental wrapping. All patients had good post-incision prognoses.Conclusions: Urgent-start PD is safe and effective for unplanned PD patients. Adequate pre-operative colonic dialysis and serum potassium level control are conducive in preventing catheter malfunction. Conservative treatment is effective in managing catheter migration alone, while preservation of the PD tube and the subcutaneous tunnel is effective for omental wrapping.

BackgroundPeritoneal dialysis (PD) is an underutilized modality for hospitalized patients with an urgent need to start renal replacement therapy in the USA. Most patients begin hemodialysis (HD) with a tunneled central venous catheter (CVC).MethodsWe examined the long-term burden of dialysis modality-related access procedures with urgent-start PD and urgent-start HD in a retrospective cohort of 73 adults. The number of access-related (mechanical and infection-related) procedures for each modality was compared in the first 30 days and cumulatively through the duration of follow-up.ResultsFifty patients underwent CVC placement for HD and 23 patients underwent PD catheter placement for urgent-start dialysis. Patients were followed on average >1 year. The PD group was significantly younger, with less diabetes, with a higher pre-dialysis serum creatinine and more likely to have a planned dialysis access. The mean number of access-related procedures per patient in the two groups was not different at 30 days; however, when compared over the duration of follow-up, the number of access-related procedures was significantly higher in the HD group compared with the PD group (4.6 ± 3.9 versus 0.61 ± 0.84, P ConclusionsUrgent-start PD results in fewer invasive access procedures compared with urgent-start HD long term, and should be considered for urgent-start dialysis.

Introduction Urgent-start peritoneal dialysis (PD) in patients with newly diagnosed end-stage renal disease (ESRD) is a well-tolerated alternative to hemodialysis (HD). The primary aim of this study was to identify the demographic and clinical characteristics of ESRD patients, as well as the presurgical, surgical, and postsurgical factors associated with urgent-start PD complications. Methods A retrospective cross-sectional observational study was performed on 102 patients with ESRD who merited urgent-start PD from January 2015 to June 2019. The primary clinical outcome measures were catheter leakage, dysfunction, and peritonitis, whereas the secondary outcomes were catheter removal, repositioning, and death. Statistical inferences were made with the χ2 or Fisher’s exact test and independent samples t tests. Results One hundred two subjects (65 men, 63.7%) 56.2 ± 15.1 years old were included in this study; 64 of the subjects had diabetes and hypertension (62.7%). Catheter leakage occurred in 8 patients (7.8%), catheter dysfunction in 27 patients (26.5%), and peritonitis in 14 patients (13.7%); meanwhile, catheter removal occurred in 6 patients (5.9%), catheter repositioning in 21 patients (20.6%), and death in 3 patients (2.9%). Peritonitis was associated with younger age (i.e., 47.0 ± 16.8 vs. 57.6 ± 14.4 years; P = 0.014; 95% confidence interval [CI]: 2.2–19.1; odds ratio [OR] 0.96; P = 0.018; 95% CI: 0.92–099), higher creatinine levels upon admission (i.e., 20.2 ± 9.8 vs. 14.1 ± 8.3; P = 0.014; 95% CI: −10.9 to −1.2), and heart failure (OR 4.79; P = 0.043; 95% CI: 1.05–21.88). Patients with abdominal hernia were 7.5 times more likely to have their catheter leak (OR 7.5; P = 0.036; 95% CI: 1.14–49.54). Catheter removal was associated with obesity (i.e., body mass index [BMI] of 31.6 ± 4.1 vs. 25.9 ± 4.9; P = 0.007; 95% CI: −9.8 to −1.6; OR 1.26; P = 0.013; 95% CI: 1.05–1.51) and Modification of Diet in Renal Disease glomerular filtration rate (MDRD-GFR) (i.e., 2.5 ± 0.6 vs. 3.7 ± 2.3; P = 0.003; 95% CI: 0.5–1.9). Conclusion Peritonitis was associated with younger age, higher creatinine levels upon admission, and heart failure; meanwhile, catheter removal was linked to obesity and lower glomerular filtration rate. Compared with previous reports, our study included patients in which PD was initiated shortly after catheter insertion, making the intervention a true urgent-start PD. This study contributes to the existing urgent-start PD literature by providing evidence that urgent-start PD with catheter opening within 72 hours has limited complications, making it a relatively safe option., Graphical abstract

Background Urgent-start peritoneal dialysis (PD) can help patients with end-stage renal diseases (ESRD) that are referred late to dialysis. However, catheter patency and related complications of urgent-start PD have not been thoroughly clarified. We investigated the clinical outcomes of urgent-start PD in a Chinese cohort. Methods We enrolled ESRD patients who received urgent-start PD (starting PD within 14 days after catheter insertion) in our center from January 1, 2006 to December 31, 2014, and followed them up for 10 years. The primary outcome was catheter failure. Secondary outcomes included short-term and long-term complications related to urgent-start PD. Results Totally 2059 patients (58.9% male, mean age 47.6 ± 15.9 years) were enrolled. Few perioperative complications were observed, including significant hemorrhage (n = 3, 0.1%) and bowel perforation (n = 0). Early peritonitis occurred in 24 (1.2%) patients (0.28 episodes per patient-year). Within the first month after catheter insertion, functional catheter malfunction occurred in 85 (4.1%) patients, and abdominal wall complications (including hernia, hydrothorax, hydrocele, and leakage) in 36 (1.7%) patients. During a median 36.5 (17.7–61.4) months of follow-up, 75 (3.6%) patients experienced catheter failure, and 291 (14.1%) had death-censoring technique failure. At the end of 1-month, 1 -year, 3-year, and 5-year, catheter patency rate was 97.6, 96.4, 96.2, 96.2%; and technique survival rate was 99.5, 97.0, 90.3, 82.7%, respectively. After adjusting for confounders, every 5-year increase in age was associated with 19% decrease of risk for catheter failure (hazard ratio [HR]: 0.81, 95% confidence interval [CI]: 0.73–0.89). Male sex (HR: 1.43, 95% CI: 1.00–2.04), diabetic nephropathy (HR: 1.56, 95% CI: 1.08–2.25) and low hemoglobin levels (HR: 0.89, 95% CI: 0.81–0.98) were independent risk factors for abdominal wall complications. Conclusions Urgent-start PD is a safe and efficacious option for unplanned ESRD patients. A well-trained PD team, a standardized catheter insertion procedure by experienced nephrologists, and a carefully designed initial PD prescription as well as comprehensive follow-up care, might be essential for the successful urgent-start PD program.

Objetivo: Comparar DP e HD como opções de início urgente de TRS, quanto à evolução, desfechos e complicações dos pacientes. Método: Estudo quasi experimental com pacientes incidentes em DP e HD em hospital universitário brasileiro, no período de julho/2014 a dezembro/2016. Incluídos indivíduos DRC estádio final que necessitaram de TRS imediata, ou seja, HD por meio de CVC ou DP cujo cateter foi implantado por nefrologista e utilizado em 72 horas, sem treinamento prévio. Pacientes em DP foram submetidos, inicialmente, a DP de alto volume (DPAV) para compensação metabólica. Após alta hospitalar, permaneciam em DP intermitente na unidade de diálise até efetivação do treinamento. Foram comparados: complicações mecânicas e infecciosas, recuperação de função renal e sobrevida. Resultados: Foram incluídos 93 pacientes em DP (G1) e 91, em HD (G2). Os grupos G1 e G2 foram semelhantes quanto à idade (58+17 vs 60+15; p=0,49), frequência de diabetes mellitus (37,6 vs 50,5%; p=0,10), outras comorbidades (74,1 vs 71,4%; p=0,67) e parâmetros bioquímicos ao início da TRS – creatinina (9,1+4,1 vs 8,0+2,8; p=0,09), albumina sérica (3,1+0,6 vs 3,3+0,6; p=0,06) e hemoglobina (9,5+1,8 vs 9,8+2,0; p=0,44). Após seguimento mínimo de 180 dias e máximo de dois anos, não houve diferença quanto a complicações mecânicas (24,7 vs 37,4%; p=0,06) ou bacteremia (15,0 vs 24,0%; p=0,11), contudo houve diferença em relação a infecção de orifício de saída (25,8 vs 39,5%; p=0,04) e manutenção da diurese (700 (0 – 1500) vs 0 (0 – 500); p
