Graft survival and postoperative complications following orthotopic renal transplantation.

The iliac fossa is the most commonly used site to place the graft in renal transplantation in adults. However, iliac fossa may not be used in various conditions. Thus, orthotopic renal transplantation becomes a viable alternative for these selected patients. Given the technically challenging surgery and limited number of patients, data on the long-term outcomes on this regard are scarce. This narrative review serves as an update on the clinical outcomes after orthotopic renal transplantation, focusing on overall recipient survival and renal graft survival, as well as postoperative complications. We found that studies to date showed a comparable survival rate in both recipients and renal grafts in the postoperative follow-up period after orthotopic renal transplantation with a lower complication rate compared to the published data on heterotopic renal transplantation. The results of our review may encourage transplant centers to reevaluate their policies to consider orthotopic renal transplantation as an alternative technique in cases where heterotopic kidney transplantation is not possible.

Triglyceride glucose index reflects the unfavorable changes of left ventricular diastolic functions and structure in uncomplicated newly diagnosed hypertensive patients.

INTRODUCTION: Left ventricular (LV) diastolic dysfunction and structural abnormalities are common cardiac changes in hypertension (HTN), and several factors other than high blood pressure (BP) may play a role in these changes. The aim of this study was to reveal the relationship between triglyceride glucose (TyG) index, a novel parameter for insulin resistance (IR), with LV diastolic function and structure in hypertensive patients. MATERIAL AND METHOD: A total of 119 newly diagnosed, untrated hypertensive patients free of diabetes and/or cardiovascular complications were included in this study. IR was estimated with the TyG index calculated from ln [fasting TG (mg/dL) × fasting blood glucose (mg/dL)/2]. Two-dimensional and Doppler echocardiographic examinations were performed to assess LV diastolic functions and structure. RESULTS: Based on median TyG index, 51 patients was assigned as group I (<8.7) and 68 patients as group II (>8.7). In patients with high TyG index, left atrial volume index (LAVi) (p < .001) LV mass index (LVMI) (p = .016), E/e' ratio (p < .001) increased, and e' velocity (p < .001) and E/A ratio (p = .028) decreased. There was a statistically significant correlation between TyG index and these parameters (all p > .05). Stepwise multiple regression analysis demonstrated that the relationship of TyG index with LV diastolic function and structure was independent of potential confounders (all p < .001). CONCLUSION: This study suggest that a high TyG index is related to LV diastolic functional impairment and structure abnormality in newly diagnosed hypertensive patients in the absence of diabetes or CVD.
