[Technical complications of peritoneal dialysis due to catheter dysfunction]

The authors analysed causes of Tenckhoff peritoneal catheter dysfunction in 17 patients treated with standard peritoneal dialysis during 23.8 +/- 8.7 months. In 8 cases any catheter dysfunction were observed. Exit-site infection/tunnel infection were observed in 5 cases. Catheter obstruction or one-way obstruction of catheters caused by peritonitis was observed in 6 patients and 1/3 of implanted catheters. 3 of these patients were transferred to hemodialysis. Non-infective complications/caused mainly by catheter migration/was observed in 3 patients and 1/3 of implanted catheters. In all these cases peritoneal dialysis was stopped. Mean one-year catheter survival was 58.8%, and two-year survival was 17.6%. The authors described the technique of catheter implantation and catheter care after operation.
