Single-tunnel ureteroscope-assisted technique for peritoneal dialysis catheter placement: a comparison with open surgery

Abstract

Objective To compare the treatment of single-tunnel ureteroscope (STU) technique and open surgery (OP) for peritoneal dialysis placement. Methods We retrospectively reviewed 139 consecutive cases of peritoneal catheters insertion, 63 patients for OP and 76 patients for STU group from May 2013 to June 2017. Both methods on their operation-related data, early catheter-related complications, and initial catheter survival were compared. Results The STU group was significantly associated with shorter operation time, hospital stay, smaller incision size, and lesser dose of anesthesia than the OP group(P<0.05). the rate of catheter obstruction in the STU group (33.3%) was significantly lower than that in the OP group (3.9%, P=0.032). Catheter migration occurred at a significantly higher rate in OP group (14.9%), than MPT group (2.6%, P=0.014). Two incisional hernia and six fluid leakage cases occurred in OP group, but none in STU group. After median two years of follow-up, catheter survival rate was significantly higher in STU group than in OP group, with one year survival rates of 96% and 83%, and two year survival rates of 86% and 63%, respectively (P=0.023). Conclusions The ureteroscopy-assisted technique for peritoneal dialysis catheter placement is a safe and reliable. Compared with traditional open surgery, it decreases operation time, postoperative complications, less catheter-related complications, and increases catheter survival. It deserves clinical using regularly. Key words: Peritoneal Dialysis; Catheters; Ureteroscopy; Surgical Procedures, Operative
