NCT07274943
This study will compare two standard ways of stitching the kidney artery to the iliac artery in adults receiving a living donor kidney transplant. The two techniques are interrupted suturing and continuous suturing. The study will review past transplant cases and follow new patients at Assiut University Urology Hospital. For each patient, the team will record details of the operation, blood flow in the kidney artery, kidney function, and any surgical or vascular complications during the first three months after surgery. The main goals are to see whether one suturing pattern shortens cold ischemia time and improves early blood flow measurements, and to explore how these techniques affect early graft function, complication rates, and short-term graft and patient survival.
NCT07234630
The aim of this research is to measure fibrinolytic activity in neoplastic pathologies in order to provide preliminary data on which to base a future, larger-scale study to determine predictive markers of complication in order to improve patient management. Primary purpose: measure plasminogen concentration on day 1 in subjects diagnosed with malignant hematological disease, solid tumors, or septic shock, with coagulopathy. Secondary purpose: * Estimate the difference in plasminogen concentration at D1 in patients with coagulopathy between subjects with a diagnosis of haematological malignancy and those with solid tumor * Estimate the difference in plasminogen concentration at D1 in patients with coagulopathy between subjects with a diagnosis of haematological malignancy and those with septic shock * Estimate the difference in plasminogen concentration on Day 1 in patients with coagulopathy between subjects with a diagnosis of solid tumor and those with septic shock. In the 3 groups, subjects with a diagnosis of haematological malignancy, solid tumor, septic shock, presenting with coagulopathy: * Evaluate the correlation between the concentration of circulating plasminogen active on Day 1 and the occurrence of a bleeding complication within 28 days of admission to critical care. * Evaluate the correlation between the concentration of circulating plasminogen active on Day 1 and the occurrence of a thrombotic complication, within 28 days of admission to critical care. * Evaluate the predictive performance of circulating active plasminogen concentration on Day 1 in the need for extra renal purification within 28 days of admission to critical care. * Estimate the differences at each time point (D1, D3, D7) in haemostasis markers and markers of fibrinolytic activity and its regulation. Assess the link between fibrinolytic activity and : * The diagnosis of disseminated intravascular coagulation (DIC), * The risk of haemorrhage * Risk of organ failures * Thrombotic risk * Risk of organ failure * Neutrophile activation and circulating NETs levels
