Changes in peritoneal dialysis protocol and clinical parameters. At PD initiation, the patient was treated with incremental PD only at night and urine volume was maintained at 600–1000 ml/day. Peritoneal dialysate was subsequently added during the day because of lack of solutes and poor ultrafiltration volume. In 2017, the patient had weight gain and leg edema, his BNP increased to 1300 pg/ml, and his fast PET test result was high average. After the switch to CCPD, body fluid management improved. BW, body weight; PD, peritoneal dialysis; CCPD, continuous cyclic peritoneal dialysis; BNP, brain natriuretic peptide
