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.
