Safety of low-dose cyclosporine therapy before transplantation in kidney allograft recipients.

Introduction: Graft dysfunction immediately posttransplantation can vary from subtle slowing of the expected decrease in creatinine concentration to frank oliguria requiring dialysis therapy for days to weeks. Risk factors for slow and delayed graft function include prolonged preservation, older donor age, and high plasma renin activity in the recipient. Cyclosporine (CsA) nephrotoxicity is another cause of early kidney allograft dysfunction.

Can Doppler ultrasonographic indices of the renal artery predict the presence of supernumerary renal arteries?

Background: Variations of the renal arteries, including the presence of supernumerary renal arteries, are important to be identified prior to renal transplant. Angiography has been the gold standard test for the pretransplant evaluation of the renal vasculature. However, this modality is expensive and invasive.

Color Doppler findings in transplanted kidneys and remnant kidneys of donors 6 to 12 months after kidney transplantation.

Objectives: Ultrasonography and color Doppler have been used extensively in the evaluation of transplanted kidney. The aim of this study was evaluation and comparison of color Doppler sonography findings in the remnant kidney of living donors and the transplanted kidney at 6 to 12 months after kidney transplantation.

Methods: In a cross-sectional study we evaluated ultrasonographic (US) and color Doppler findings in 20 kidney allograft recipient and donors.
