title: Replacement of the early-control IVU after ureteral reimplantation by ultrasonography.
abstract: Many intravenous urographies (IVU) are still made shortly after ureteral reimplantation as a routine procedure to evaluate the function of both kidneys and to exclude a severe distal ureteral obstruction known as a complication of the operation (Broaddus et al., 1978). By studying two groups of patients we present an evaluation of the use of this IVU and the possible replacement by ultrasonography (US). The first group consisted of 119 cases with 155 reimplanted ureters. All of the patients underwent an IVU within two weeks and again three months after the operation. The second group included 35 patients, who underwent 55 reimplantations: US of the kidneys was performed within two weeks and three months and also one year after operation. In the first group three patients needed a second reimplantation because of a developed distal ureteral stenosis after three months. The second IVU showed severe dilatation in all of them. In two patients of the second group we also saw an increase in dilatation during follow-up within three months, for which a ureteral reimplantation was indicated. There was not a single case in which the outcome of the early IVU or US gave rise to a serious change in postoperative management. Our conclusion is that the early postoperative IVU, should be replaced by US of the kidneys, the result of which should function as a baseline for further follow-up studies.
