[Pre- and postoperative clearance studies in the individual kidneys in juvenile kidney surgery].

In 1978 43 patients have been operated in the Department of Pediatric Surgery, Krankenhaus München-Schwabing, because of recurrent urinary-tract infections with ureterovesical reflux or obstructive urinary-tract diseases. In all patients a split whole body clearance-study with a method modified after the method of Mühle with 131J-Hippuran was carried out pre- or postoperatively, respectively. In 78,5% of these cases the clearance-results were corresponding to the results of x-ray examination; 6 of the remaining patients had a worse clearance result and 3 had a better result than the x-ray findings would have suggested.
