PDC implantation and PD schemes
PD
All patients received Tenckhoff catheters and prophylactic antibiotics were administered preoperatively. Two experienced nephrologists performed catheter implantations using open dissection, and those through laparoscopy were performed by a surgeon. All the PDC were implanted at the day surgery center. USPD was initiated 48 h after PDC implantation and continued for five days during hospitalization.The PD schemes were based on the patients’ BSA [Standard prescription for the patients of USPD.A-MPD: automated peritoneal dialysis combined with manual fluid exchange peritoneal dialysis; MPD: manual fluid exchange peritoneal dialysis.Nurses treating PD taught and assisted patients in completing manual fluid exchanges and performing the cyclers. All patients were trained in manual fluid exchange by nurses treating PD during hospitalization and were administered the test before discharge. However, patients who failed the test were retrained and reevaluated until they qualified. The time spent by the nurses treating PD and the test scores of the patients were recorded. Finally, all patients were followed up six months after discharge.
