[Surgical management of ureteral evacuation disorders using a surgical gama camera]

By means of the radionephrogram it is possible to discover a disturbance of the excretion of the upper urinary tract at an early stage. Since there can be no pathological function of the urinary excretion without negative effect on the renal function, measures must be taken in order to prevent this from happening. By conventional surgical methods the eventual success of an operation can be judged only at a postoperative stage, sometimes an additional operation will prove necessary. A continuous intraoperative registration of a sequential scintigram, using a gammascintillation camera that has beem modified into an operation table, enables the control of method and extention of the operation. This method permits an optimal surgical result and we may save the patient from the strain of a possible second correcting operation. The method is being described by means of a case.
