title: Importance of sonography with furosemide in continuing dilatation after pyeloplasty.
abstract: The continuance of collecting system dilatation after plastic repairing of the ureteropelvic junction in children progressed hydronefrosis may have two causes, the first one is a great progress of the process, that do not allow to repair the dilatation, the second one is to be a failure with the operation. Another treatment depends on differentiating there two causes. Authors used ultrasonography with furosemide test. By comparing sonogram before and after giving furosemide. They described whether the continuance of collecting system dilatation can be caused by a urodynamic obstruct. The result is that the ultrasonography with furosemide is a simple of orientation noninvasive method, which can be used several times without risks for the children. According to experience of the authors more precise is the method with oral furosemide application that the intravenous. It is a method of orientation which can be filled by dynamic scintigraphy in case of suspicion on bad evacuation with furosemide. Then if the obstruction is confirmed, we can indicate the excretory urography with furosemide.
