However, complications associated with the peritoneal dialysis catheter (PD catheter) can lead to increased patient morbidity and thus the necessity of PD catheter removal. While prior studies have identified patient-related risk factors, the impact of various surgical risk factors on technical survival is yet to be elucidated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective, monocentric cohort study was conducted including all patients who underwent PD catheter implantation through an open surgical technique utilizing a small surgical incision above the rectus abdominis muscle from January 2010 to March 2022. The technical survival of PD catheters was observed retrospectively over a period of three years and the reasons for PD catheter removal were summarized. Furthermore, Cox regression analysis was conducted to evaluate potential risk factors for a reduced technical survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 340 patients were included, and a median PD catheter functionality of 980 days was presented in this study.
