Data underlying the publication: Advancements in Peritoneal Dialysis Catheterization: Introducing a Modified Single-Port Laparoscopic Technique

This dataset contains the complete anonymised clinical and operative records of a single-centre, retrospective, two-arm cohort study conducted at the Department of Nephrology, First Affiliated Hospital of Harbin Medical University, People’s Republic of China. The study compared a modified single-port laparoscopic (SLC) versus conventional open surgical (OSC) peritoneal-dialysis (PD) catheter insertion technique in adults with end-stage renal disease (ESRD). Ethics and legal complianceThe study protocol was reviewed and approved by the Ethics Committee of the First Affiliated Hospital of Harbin Medical University (Approval No. IRB-AF/SC-04/02.0). All participants provided written informed consent; personal identifiers were removed before compilation of this public repository. Study population and inclusion/exclusion criteriaConsecutive patients ≥ 18 years who received their first PD catheter between March 2023 and September 2023 were screened. Inclusion: ESRD scheduled for first PD catheter. Exclusion: severe cardiopulmonary dysfunction, pregnancy, abdominal-wall defects, active intra-abdominal infection/mass, or other surgical contraindications (e.g. severe psychiatric disorder). Thirty eligible patients were enrolled and followed until September 2024 (minimum follow-up 12 months).

本数据集收录了中华人民共和国哈尔滨医科大学附属第一医院肾内科开展的一项单中心回顾性双臂队列研究的完整匿名化临床与手术记录。该研究对比了改良单孔腹腔镜（single-port laparoscopic, SLC）与常规开放手术（conventional open surgical, OSC）腹膜透析（peritoneal-dialysis, PD）导管置入术在终末期肾病（end-stage renal disease, ESRD）成人患者中的应用效果。

研究人群与纳入排除标准：筛选2023年3月至2023年9月期间接受首次PD导管置入的18岁及以上连续患者。纳入标准：拟行首次PD导管置入的终末期肾病患者。排除标准：严重心肺功能不全、妊娠、腹壁缺损、活动性腹腔感染/肿物或其他手术禁忌证（如严重精神障碍）。最终入组30例符合条件的患者，随访至2024年9月，最短随访时长为12个月。
