In particular, long\u2010term dialysis seems to contribute to changes in median nerve texture which lead to an increased risk for CTS<\/jats:styled-content>. The current study was designed to evaluate if these structural changes can be detected by HRS<\/jats:styled-content> (high\u2010resolution sonography). Additionally, the current study aimed to determine if changes are reversible after termination of dialysis.<\/jats:p><\/jats:sec>Methods<\/jats:title>Fifty patients (98 hands) were included in the study. The study population was subdivided into three groups: patients without any history of renal disease (H, n<\/jats:italic>\u00a0=\u00a020), patients with long\u2010term dialysis (D, n<\/jats:italic>\u00a0=\u00a010), and patients after renal transplantation (TX<\/jats:styled-content>, n<\/jats:italic>\u00a0=\u00a020). None of the patients had any clinical symptoms for a median nerve compression syndrome. The CSA<\/jats:styled-content> (cross\u2010sectional area) of the median nerve was evaluated both 12\u00a0cm proximally of the carpal tunnel inlet and directly at the carpal tunnel inlet. The ratio of those two values, the WFR<\/jats:styled-content> (wrist forearm ratio), was calculated and analyzed.<\/jats:p><\/jats:sec>Results<\/jats:title>The CSA<\/jats:styled-content> demonstrated significantly higher values in dialysis (D) and transplanted (TX<\/jats:styled-content>) patients compared to the healthy (H) control group (P<\/jats:italic>\u00a0<\u00a00.001). No significant differences were detectable between the D and TX<\/jats:styled-content> groups. Specifically, there was no significant difference in the WFR<\/jats:styled-content>.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Patients with chronic renal disease demonstrate significantly higher CSA<\/jats:styled-content> values compared to their healthy counterparts.
