Ultrasonography was performed to detect postoperative complications in ten cases of renal transplantation.
Lymphocele was detected in three cases, in which ultrasonographic examination proved to be useful in determining the treatment guide line of lymphocele.
On the other hand, acute rejection was observed in nine cases. Our main ultrasonographic findings at the time of acute rejection were prominent pyramids, increase of the parenchymal thickness and increased parenchymal echogram which became similar to that of the central portion. In mild rejection cases, no positive finding or prominent pyramids were detected. In a moderate rejection case, renal parenchyma was thickened. In a severe rejection case, the boundary between parenchymal and central echoes became indistinct.
Acute tubular necrosis (ATN) occurred in one case, in which ultrasonographically positive finding was not detected.
In conclusion, ultrasonography is useful in detection and follow-up of lymphocele and would be one of the tools for the diagnosis of rejection crisis in renal transplantation.
