Correction of CAPD catheter displacement using alpha-replacement method.

Background Malposition of the tip of a continuous ambulatory peritoneal dialysis (CAPD) catheter may impede a dialysis, and an invasive method, such as open or laparoscopic surgery, is necessary to correct its position. The alpha-replacement method is a nonsurgical procedure; however, the reported clinical experience has been limited. We thus reviewed our 19 cases to clarify the efficacy of this method.
