| Objectives:Currently,urgent start peritoneal dialysis（USPD）is a commonly used urgent dialysis modality for patients with end stage renal disease（ESRD）.However,it remains controversial whether it is feasibility to initiating PD within 24 hours.In this context,we examined the short-term outcomes of a break-in period（BI）of 24 hours for patients undergoing USPD.Methods:In this real-world retrospective study,we evaluated USPD patients between 1January 2013 and 31 August 2020,which divided into the BI≤24h group and the BI> 24 h group according to BI.The primary outcome were the incidences of mechanical and infectious complications in 2 weeks,1 month,3 months,6 months,respectively,the second outcome was the mortality.Results:Altogether 449 USPD patients were entered into this study,of whom 219 in the BI≤24h group and 230 in the BI>24h group.We observed no significant differences between the two groups in mechanical complications and infectious complications in different follow-up time（2 weeks,1 month,3 months,and 6 months）（p>0.05）.Results of multiple logistic regression analysis evaluated that BI within 24 hours was not an independent risk factor for mechanical complications,catheter migration and infectious complications（p>0.05）.K-M curves showed that the two groups had comparable mortality in 6 months,1 year,3 years and 5years（p>0.05）.Conclusions:Initiating PD within 24 hours without an increase in the incidence of mechanical complications and infectious complications.Initiating PD within 24 hours is a feasibility treatment for patients. |
