Clinical application of right low-position modified peritoneal dialysis catheterization

Area of Science:

• Nephrology
• Surgical Techniques
• Medical Devices

Background:

• Peritoneal dialysis is a vital renal replacement therapy.
• Catheter malposition is a common complication, leading to suboptimal dialysis and increased morbidity.
• Traditional catheterization techniques have limitations in preventing malposition.

Purpose of the Study:

• To evaluate the efficacy of a modified low-position peritoneal dialysis catheterization technique.
• To compare the incidence of catheter malposition between the modified and traditional methods.
• To assess the clinical value of the modified technique in reducing complications.

Main Methods:

• A retrospective study comparing 48 patients (traditional group) and 95 patients (modified group).
• The modified technique involved right low-position catheterization.
• Key outcomes measured included inflow/outflow times, ultrafiltration volume, and catheter malposition rates.

Main Results:

• No significant differences in dialysis efficiency (inflow/outflow times, ultrafiltration) were observed between groups.
• The modified group had a 0% incidence of post-operative catheter malposition.
• The traditional group experienced an 18.75% malposition rate, with 6 patients requiring revision surgery (P<0.01).

Conclusions:

• Right low-position modified peritoneal dialysis catheterization effectively prevents catheter malposition.
• This technique demonstrates superior efficacy compared to traditional methods.
• The modified approach is recommended for clinical promotion due to its significant reduction in malposition rates.
