Objectives of the study were to investigate impact of ischemic preconditioning (Ipre) and sulforaphane (SFN) and combination of them on nuclear factor 2 erythroid related factor 2 (Nrf2) gene and its dependent genes, heme oxygenase-1 (HO1) and NADPH-quinone oxidoreductase1 (NQO-1) and inflammatory cytokines TNF-alpha, IL1beta, and intercellular adhesion(More)
OBJECTIVES To report a high-volume institution experience with salvage techniques for vascular accidents during live donor renal allotransplantation. METHODS Between March 1976 and January 2011, 2208 recipients underwent live donor renal allotransplantation. A retrospective review of recipients with vascular accidents - renal artery thrombosis and renal(More)
OBJECTIVES This prospective study was designed to develop a steroid and calcineurin inhibitor-free regimen for kidney transplants using alemtuzumab. MATERIALS AND METHODS A single dose of alemtuzumab (30 mg) was given preoperatively. Phase 1: Twenty-one patients were randomized into 2 groups; the tacrolimus (n=11) and the sirolimus groups (n=10). Steroids(More)
PURPOSE To analyse the long-term outcome in relation to multiple graft arteries (MGA) in live-donor renal transplantation, and assess its effect on graft and patient survival. PATIENTS AND METHODS Between March 1976 and November 2009, a total of 2100 live-donor renal transplants were carried out at our centre. Patients were stratified according to the(More)
OBJECTIVES We report on the long-term follow-up of managing allograft stones at a single tertiary referral institution and review the relevant literature. MATERIALS AND METHODS A retrospective analysis of renal allograft recipient charts was performed to identify patients who developed allograft lithiasis between 1974 and 2009. Patient and stone(More)
Activation of Nrf2 by Ischemic Preconditioning and Sulforaphane in Renal Ischemia/Reperfusion Injury: A Comparative Experimental Study By Ahmed A. Shokeir*, Nashwa Barakat*, Abdelaziz M. Hussein†, Amira Awadalla*, Ahmed Harraz*, Shery Khater*, Kamel Hemmaid $ , Ahmed I. Kamal* From *Urology and Nephrology Center, †Physiology Department, Faculty of Medicine,(More)
Urolithiasis in the context of renal transplant is a quite rare event that requires keeping a higher index of suspicion and vigilance. Donors with incidentally discovered asymptomatic renal stones "donor gifted lithiasis" are potentially considered for donation should they are not recurrent stone formers and in the absence of active biochemical disorders.(More)
PURPOSE There is a lack of a standardized reporting methodology for surgical complications of pediatric renal transplantation. We applied Martin criteria and the modified Clavien-Dindo classification in pediatric renal transplantation. MATERIALS AND METHODS We retrospectively reviewed the charts of 447 patients 20 years or younger who underwent renal(More)
INTRODUCTION To determine risk factors for and the effects of impaired perfusion (IP)-"reduced or non-perfusion"-of graft areas supplied by an accessory artery on allograft function. OBJECTIVES One hundred five consecutive grafts with multiple renal arteries were prospectively evaluated using Doppler ultrasound (US) to detect the perfusion of allograft(More)
BACKGROUND Increasing the living-donor pool by accepting donors with an isolated medical abnormality (IMA) can significantly decrease the huge gap between limited supply and rising demand for organs. There is a wide range of variation among different centres in dealing with these categories of donors. We reviewed studies discussing living kidney donors with(More)
