Background/Aims: Continuous ambulatory peritoneal dialysis (CAPD) is an established treatment in patients with end-stage renal disease (ESRD), and innovations in the connection system have improved the survival of peritoneal dialysis patients over the last two decades. We investigated the outcome of CAPD over a 15-year period at our institution.
Methods: Patients who underwent peritoneal dialysis since 1994 were recruited retrospectively. Patients younger than 15 years at the initiation of CAPD and those who had less than 1 month of follow-up or missing data were excluded. The technique survival rate and causes of technique failure were evaluated.
Results: In all, 608 CAPD patients (342 males, 56.3%) were analyzed using the Kaplan-Meier method and log-rank test. The mean age at the start of CAPD was 50.7±15.1 years and the mean duration of CAPD was 50.2±41.5 months. The most common primary renal disease was diabetes (39.6%), followed by chronic glomerulonephritis (37.2%) and hypertension (13.0%). The 1-, 3-, 5-, and 10-year death-censored technique survival rates were 97.3, 91.7, 82.8, and 67.5%, respectively. Sex or diabetic status did not affect the technique survival rate. Patients younger than 60 years at the start of CAPD had a better technique survival than older patients (p=0.005). The main cause of technique failure was peritonitis (71.6%), followed by mechanical malfunction (10.5%), ultrafiltration failure (7.4%), and inadequate dialysis (6.3%).
Conclusions: Complicating peritonitis was the most common cause of CAPD technique failure at our center. To reduce the technique failure in high-risk groups, more intensive management is needed.
