B-mode ultrasound and color Doppler evolution of the transplanted kidney

Abstract

Introduction: chronic kidney disease is a progressive damage of the kidney, its most advanced and irreversible manifestation is the terminal chronic kidney disease, with the consequent need of renal replacement therapy. Objective: to describe the evolution by B-mode ultrasound and color Doppler of the transplanted kidney. Methods: a descriptive, longitudinal and prospective development research was carried out. The study population was conformed by all the patients who received as substitute renal treatment a transplant of a new organ from April 2016 to October 2017 in the Hospital "Arnaldo Milián Castro" of Villa Clara. The sample was constituted in a non-probabilistic way by 39 patients. Results: patients with normal echogenicity of renal parenchyma, good cortical-medullary relationship, acute rejection, increased resistance index and drop of diastole predominated. Perirenal collection was the most frequent complication. At the end of the study there were 28 patients left, 11 lost the transplanted organ. Conclusions: ultrasound, due to its wide availability, its sensitivity, its innocuousness and its low cost, is the study of choice in the follow-up of patients with renal transplant because it allows characterizing, in an adequate way, the complications of renal transplant and it is a determining part in the evolution of the graft and the recipient.
