BACKGROUND: Incremental peritoneal dialysis (IPD) is the practice of initiating PD exchange less than 4 times a day in consideration of residual renal function (RRF). This study determined whether IPD could be used for urgent-start peritoneal dialysis (USPD) patients when starting dialysis, and when compared to full-dose PD, could IPD affect the RRF in USPD patients.
MATERIALS AND METHODS: 169 USPD patients with eGFR between 4 and 6 mL/min/1.73m2 were retrospectively analyzed. The duration of follow-up was 1 year. Patients were divided into an incremental PD (i-PD) group (dialysis dose ≤ 6,000 mL) and a full-dose PD (f-PD) group (dialysis dose ≥ 8,000 mL). The demographics, clinical indices, peritoneal transport function, dialysis adequacy, and complications of peritoneal dialysis were compared between both groups.
RESULTS: (1) 111 patients (average age 45.01 ± 12.84 years) were included in the i-PD group and 58 patients (average age 43.5 ± 15.62 years) in the f-PD group. The demographics and clinical indices of both groups before PD were similar (p < 0.05). (2) During the follow-up period, the dialysis dose in the f-PD group exceeded that of the i-PD group (p < 0.05). The dialysis adequacy of both groups was as expected. (3) During the follow-up period, peritoneal transport function, the RRF, the blood pressure control, correction of anemia, and correction of calcium and phosphorus abnormalities were similar in both groups. (4) The peritoneal dialysis-related infection, mechanical complications, and technical survival rate were similar between groups.
CONCLUSION: Incremental PD did not cause a rapid decline of RRF in USPD patients. The dialysis effect and complications from it, were similar to full-dose peritoneal dialysis. Thus, USPD patients can be treated by IPD.
