신이식 후 조기 수술적 합병증의 99mTc-MAG3 신스캔

Abstract

The purpose of this study is to evaluate the usefulness of 99mTc-Mag3 renal scan in the diagnosis of early surgical complication of renal transplantation, compared with ultrasonography. Two hundred three cases of renal transplantations, from January 2000 to December 2004, were studied retrospectively. 99mTc-MAG3 renal scan and ultrasonography were routinely performed for evaluation of allograft kidney at postoperative day 3, 7, 14, and 21 or 28. There were 13 early surgical complications (6.4%) from 203 recipients during the first one month after transplantation. And six cases of urological complications, six cases of hematoma, and one case of lymphocele were noticed. 99mTc-MAG3 renal scan showed abnormality in 10 cases (76.9%) of 13 early surgical complications. 99mTc-MAG3 renal scan detected all six urologic complication (100%), four of six hematomas (66.7%), but did not one lymphocele. Ultrasonography showed abnormal findings in eight cases of 13 early surgical complications (61.5%): one of four urine leakages (25%), all two urinomas (100%), and one lymphocele (100%). 99mTc-MAG3 renal scan is more sensitive than ultrasonography for the detection of early surgical complications following renal transplantation.
