Conclusion
Despite the low incidence of postoperative renal hematoma following
kidney transplantation, it can have serious complications affecting the
outcome of the graft and even the patient. When the renal hematoma is
subscapular with a mass effect on the renal parenchyma and intrarenal
hyperpressure, CDUS can show a falsely elevated RI, that can mimic ATN.
The mainstay of the treatment would be the emergent evacuation of the
hematoma with postoperative imaging control.
