Effect observation of the fixation methods of peritoneal dialysis catheter on the abdominal wall under direct vision

Objective To investigate the different effect of catheter abdominal fixed and unfixed surgical methods on the malposition of the peritoneal dialysis catheter(PDC).Methods Totally 38 patients with chronic renal failure were randomly divided into two groups: the fixed group,the catheter was fixed on the abdominal;the unfixed group,the catheter was not fixed on the abdominal.Comparing the incidence of the PDC malposition and the dialysis effect.Results The incidence of the PDC malposition was obviously reduced(0) in fixed group compared to 15% in unfixed group.The volume of input/output and ultrafiltration were not significantly different in two groups.Conclusion The surgical method of PDC abdominal fixed can effectively reduce the PDC malposition.
