This study reports our experience with permanent peritoneal catheters. From July 1983 until December 1997, 225 catheters were implanted surgically in 207 patients (120 males, 87 females) with mean age of 58+/-16 years (range: 2-82 years), and a mean duration of continuous peritoneal dialysis (CAPD) of 21.9+/-21.3 months (range: 1-145 months). Two hundred and seventeen catheters were used in 199 patients suffering from end-stage renal disease (ESRD), and 8 catheters in 8 patients with end-stage heart failure resistant to medical therapy. One patient used 3 catheters and 16 patients used 2 catheters. The catheters used were: Tenckhoff, 2; Oreopoulos-Zellerman-1 (OZ-1), 10; OZ-2, 205; and OZ-pediatric, 8. All catheters were implanted by the same surgical team, through a paramedian incision under local anesthesia. By life table analysis, the actuarial survival rates at 1 year, 2 years, 3 years, and 5 years were 97%, 92%, 87%, and 82% respectively for all catheters. The catheter-related complications were: 5 obstructions, 2 dislodgments, 13 dialysate leaks (6 early; 7 late), 90 exit-site/tunnel infections (in 56 patients), 2 cuff extrusions, and 37 hernias (in 31 patients). Eighteen catheters were replaced for persistent peritonitis (15 cases), dislodgment (1 case), obstruction (1 case), and accidental shortening (1 case). The total observation period was 4526 patient-months. The overall incidence of peritonitis was one episode per 15 patient-months, and of exit-site/tunnel infections was one episode per 50 patient-months, with a significant improvement during the last years. We conclude that OZ catheters implanted surgically through a paramedian incision have a very high survival rate and a low complication rate.
