Abstract: 【Abstract】Objective This study assessed the efficacy and safety of the modified percutaneous peritoneal dialysis catheter placement in urgent-start peritoneal dialysis patients. Methods A total of 76 patients diagnosed as end-stage renal disease were enrolled, they were divided into group A (with modified percutaneous placement of peritoneal dialysis catheter,n=34)and groupB (with conventional placement of peritoneal dialysis catheter,n=42).The demographic and clinical characteristics,past abdominal operation history,surgery time,hospital stay after operation,early and late complications were observed. Results The operative time of group A was shorter than that of group B (t=-6.142，P=0.009)，the incidence of leakage in group A was lower than group B within one month (χ２=8.341，P=0.001)，the incidence of catheter displacement in group A was lower than group B within one month(χ２=7.523，P=0.003)，the incidence of rectus abdominis hemorrhage in group A was higher than group B (χ２=5.272，P=0.018); the incidence of catheter displacement in group A was lower than group B after one month (χ ２=11.724，＜0.001)，the incidences of omentum wrapping (χ ２=0.659，P=0.191), peritonitis (χ２=0.091，P=0.958), pleuro-abdominal fistula (χ２=0.148，P=0.809) and hernia (χ２=0.148，P=0.809) showed no difference between the two group. Conclusions The modified percutaneous placement of peritoneal dialysis catheter is effective, safe and easy to learn, which reduce leakage and catheter displacement significantly compared with conventional placement of peritoneal dialysis catheter, and worth clinical promotion in urgent-start peritoneal dialysis patients.
