Retrospective analysis reveals high clinical maturation rates with specific vessel depth strategies in hemodialysis patients.

To understand the factors contributing to high clinical maturation rates of arteriovenous fistulas in Japan.
Conducted a retrospective study of 22 hemodialysis patients with temporary catheters and AVF construction.
All patients were cannulated with plastic cannulas by residents after surgeon assessment and ultrasound confirmation.
Primary outcome measured was the clinical maturation rate; secondary outcomes included anatomical maturation rate and cannulation site.
Clinical maturation rate reached 95.5% in the study cohort (N=21/22).
Only 4.8% met the anatomical maturation rate criteria based on the Rule of 6s (N=1/21).
100% of sites met the depth criterion (<6 mm), but most failed the size criterion (mean 4.0–4.3 mm).
The elbow area was used for 90.5% of blood removal or return sites.

Suemitsu et al. (2026) studied this question.
