Introduction: Ureteral stricture (US) in the kidney transplant recipient is a rare complication that can lead to morbidity and graft loss. Risk factor recognition is crucial in the prevention and management of this entity. Delayed graft function (DGF), as defined by the need for dialysis in the first week after transplantation, has been proposed as a risk factor in previous studies. Our objective is to determine the impact of DGF in US development in kidney transplant patients. Methods: We designed a matched case-control study. US cases in kidney transplant recipients were identified in the 2008–2017 period. We defined US as the rise in serum creatinine associated with findings suggesting obstruction in ultrasound, scintigraphy, or retrograde pyelogram; any other cause of graft dysfunction was excluded. Controls were defined as kidney transplant recipients from the same population and period without US, matched in a 1:2 fashion by age, sex, and donor type. Results: From 532 kidney transplant patients, 31 cases and 62 controls were included. Cumulative US incidence was 58 per 1000 cases. When calculating for odds ratio (OR), post-operative urinoma (OR 3.2; 95% confidence interval [CI] 2.36–4.37) and ureteral duplication (OR 3.29; 95% CI 2.40–4.51) were associated with an increased risk for US, while DGF was not found to be statistically significant as a risk factor (OR 3.3; 95% CI 0.96–11.52). No statistically significant differences were found between groups in other pre- and post-transplant-related factors. Conclusions: DGF was not associated with US in our cohort; however, ureteral duplication and postoperative urinoma were associated with an increased risk of graft ureteral stenosis development.

Pregnancy And Delivery

Abstract Background and Aims This study aimed to evaluate whether the experience of pregnancy and delivery would be associated with poor maternal outcome among kidney transplant recipients. Method A total of 401 female transplant recipients from the Osaka University Transplantation Group Database were included in this study. 73 women who underwent renal transplantation between 1970 and 2017 and became pregnant and delivered at Osaka University Kidney Transplant Group Hospitals. Multivariable logistic regression analysis was used to assess the impact of pregnancy and delivery on renal transplant recipient outcome after one-to-one propensity score (PS) matching for 12 variables including serum creatinine at one year post-transplant between the parous group and the nulliparous group. The outcomes were kidney graft survival and patient survival. Results In all patients before PS matching, 75 (18.7%) of the 401 patients died and 137 (34.2%) of the 401 patients lost their kidney grafts during the follow-up period. In the multivariate analysis, pregnancy and delivery was not a significant risk factor for death (adjusted HR 0.662 [95%CI, 0.265-1.656], p-value 0.378) and for death-censored graft survival (adjusted HR 1.224 [95%CI, 0.683-2.196], p-value 0.497). In the PS matched population, 14 (17.5%) of the 80 patients died and 31 (38.8%) of the 80 patients lost their grafts. In the multivariate analysis, pregnancy and delivery was not a significant risk factor for death (adjusted HR 0.611 [95%CI, 0.180-2.072], p-value 0.430) and for death-censored graft survival (adjusted HR 1.308 [95%CI, 0.501-3.416], p-value 0.584). Conclusion Pregnancy and delivery after kidney transplantation was not associated with poor kidney transplant outcome in recipients with adequate and stable graft function.

All Cause Mortality

Abstract Background Sclerostin is a hormone contributing to the bone-vascular wall cross talk and has been implicated in cardiovascular events and mortality in patients with chronic kidney disease (CKD). We analyzed the relationship between sclerostin and mortality in renal transplant recipients. Methods 600 stable renal transplant recipients (367men, 233 women) were followed for all-cause mortality for 3 years. Blood and urine samples for analysis and clinical data were collected at study entry. We performed Kaplan–Meier survival analysis and Cox regression models considering confounding factors such as age, eGFR, cold ischemia time, HbA1c, phosphate, calcium, and albumin. Optimal cut-off values for the Cox regression model were calculated based on ROC analysis. Results Sixty-five patients died during the observation period. Nonsurvivors (n = 65; sclerostin 57.31 ± 30.28 pmol/L) had higher plasma sclerostin levels than survivors (n = 535; sclerostin 47.52 ± 24.87 pmol/L) (p = 0.0036). Kaplan–Meier curve showed that baseline plasma sclerostin concentrations were associated with all-cause mortality in stable kidney transplant recipients (p = 0.0085, log-rank test). After multiple Cox regression analysis, plasma levels of sclerostin remained an independent predictor of all-cause mortality (hazard ratio, 1.011; 95% CI 1.002–1.020; p = 0.0137). Conclusions Baseline plasma sclerostin is an independent risk factor for all-cause mortality in patients after kidney transplantation.
