Abstract Carpal tunnel syndrome (CTS) is the most common mononeuropathy in clinical practice. Some patients with end-stage renal disease (ESRD) often associate with tertiary hyperparathyroidism, and ultimately need parathyroidectomy (PTX). However, no studies have definitively demonstrated an effect of PTX on ESRD patients’ quality of life. We selected 1686 patients who underwent PTX and 1686 patients who did not receive PTX between 2000 and 2010. These patients were propensity-matched with others by age, sex, and comorbidities at a ratio of 1:1. We used single and multivariable cox proportional hazard models to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). In this study, 116 ESRD patients developed CTS, and the CTS incidences were 7.33 and 12.5 per 1000 person-years for the non-PTX and PTX group. The results reveal that the incidence curve for the PTX group was significantly higher than that for the non-PTX group (log-rank test, P = .004). After adjustments were made for sex, age, and baseline comorbidities, the PTX group had a 1.70-fold higher risk of CTS (hazard ratio (HR) = 1.70, 95% confidence intervals (CI) = 1.17–2.47) than the non-PTX group. The results also demonstrated that female patients (HR = 1.60, 95% CI = 1.06–2.42) and patients with one or more comorbidities (HR = 1.79, 95% CI = 1.23–2.60) might have an increased risk of CTS. The subhazard ratio for CTS risk was 1.62 (95% CI = 1.12–2.36) for the PTX group compared with the non-PTX group in the competing risk of death. In conclusion, we revealed that ESRD patients who had undergone PTX may have an increased risk of CTS.
