Effect of glycopyrrolate on the postoperative urine output of patients following kidney transplantation: a retrospective observational study

Objectives To compare the urine output and estimated glomerular filtration rate (eGFR) of patients postoperatively administered sugammadex or glycopyrrolate 7 days following kidney transplantation (KT). Methods We retrospectively enrolled 134 consecutive patients who underwent KT under general anesthesia. Their urine output and eGFR were recorded every 24 hours between postoperative day (POD) 1 and 7. We used regression analysis to evaluate the relationship between the reversal agent administered and the outcomes of the participants. Results The urine output and eGFR of the participants did not differ between the two groups. Multivariate analysis showed that body mass index (BMI) (odds ratio (OR) 1.21; 95% confidence interval (CI) 1.05–1.40), diabetes mellitus (OR 3.14; 95% CI 1.07–9.16), neurovascular disease (OR 7.00; 95% CI 1.61–30.42), and the duration of surgery (OR 1.01; 95% CI 1.00–1.01) were associated with lower urine output on POD 7. In addition, only BMI (OR 1.25; 95% CI 1.09–1.42) was associated with low eGFR on POD 7. Conclusions The urine output and eGFR of patients administered sugammadex or glycopyrrolate following KT did not differ 7 days later. Moreover, glycopyrrolate does not affect urine output or eGFR on POD 7, according to multivariate regression analysis.
