The valency of sequence scintiscanning with 131-I-Hippurat as seen in 530 examinations at transplanted kidneys for recognizing the shedding reaction and judging anuric kidneys

Within the framework of this work, 530 examinations were carried out on 50 patients. The course of 16 anuric kidneys was correctly reflected in 15 cases. Out of 45 sheddings, 38 were recognized, 7 were not. 312 examinations were carried out at stable kidneys. 288 were correctly negative, 24 were falsely positive. It could be seen in the wrong diagnosis: fiever, long time to the preexamination, obstruction, thrombosis, increase in leucocytes, renal rupture, medicamentous influences; clinical shedding symptoms already in the first postoperative examination. In 12 of the 24 falsely positive results, the cause of the mistake could not be found. It was found out that the 1st postoperative examination is of a prognostic value. Furthermore it was shown at 2 cases that a kidney which remains dumb on the functional scintiscanning is not in all cases an indication of a nephrectomy. The functional scintiscanning with 131I-Hippurat was found to be a valuable examination in the course control of a transplanted kidney, especially for the diagnosis of the shedding. (orig./MG)
