Clinical efficacy of a modified no-touch technique in the establishment of autologous arteriovenous fistula

To explore the clinical efficacy of a modified no-touch technique (MNTT) in establishing autogenous arteriovenous fistulas (AVF) in hemodialysis patients. A total of 63 patients with AVF which was first established by MNTT in the Department of Nephrology, Suzhou Science and Technology Town Hospital from January 2021 to August 2022 were retrospectively included. The clinical data, ultrasound evaluation data of AVF, AVF maturity rate and AVF patency rate were collected. Subsequently, the AVF rate of patients in the MNTT group was compared with the patency rate of patients in the conventional operation group in the same hospital from January 2019 to December 2020. The Kaplan-Meier method was used to draw the survival curve, and the log-rank test was used to compare the difference in postoperative patency rate between the two groups. There were 63 cases in the MNTT group, with 39 males and 24 females, and aged (60±17) years. Meanwhile, there were 40 cases in the conventional operation group, including 23 males an
