Abstract: 【Abstract】 Objective To explore the clinical effect of the improved method for insertion of peritoneal dialysis (PD) catheters in patients with end-stage renal disease (ESRD). Methods From February 2009 to April 2012, sixty-nine ESRD patients who needed catheterization for PD were prospectively and randomly
divided into two groups, group A (improved method, using the sector dispelling apparatus to guide PD catheter insertion, n=35) and group B (conventional method for PD catheter insertion, n=34). Clinical data at baseline and follow-up information were collected. Complications including catheter dislocation, obstruction, leakage and pain were compared between the two groups. Results At the baseline, clinical conditions including age and primary disease had no differences between the two groups (P＞0.05). No differences in superficial infection and tunnel infection around the catheter (χ2=4.899,P＞0.05), catheter obstruction, leakage and pain were found between the two groups (χ2=4.417,P＞0.05). Catheter dislocation occurred in 3 cases (8.57%) in group A and 10 cases (29.41%) in group B (P<0.05). Re-insertion of the catheter was performed in 2 cases (5.71%) in group A and in 8 cases (23.53%) in group B (P <0.05). Conclusion The improved method for insertion of PD catheters can reduce the rates of catheter dislocation and re-insertion without increase of infection and
complication due to mechanical injuries.
