[Percutaneous, transrenal balloon catheter dilatation. A possibility for the treatment of uretero-enteral implantation stenoses].

In contrast to the undisputed position of percutaneous translumenal balloon catheter dilation of arteriostenoses, the use of this method on strictures of the efferent urinary tract is hardly known. Encouraged by initial promising reports, we present our own application of this method in a cases of bilateral recidive implantation stenoses with progressive hydronephrosis following operative revision of a Bricker conduit. Balloon dilation (Grüntzig catheter) was performed several times antegradely via previously made bilateral percutaneous pyelonephrostomies. The follow-up period was 12 months. Clinical consolidation of the patient's state with an initial unilateral morphological confirmation of improvement in the drainage of urine is an encouragement to repeat the procedure. If the late result is also good and when we have more experience, this method could be an acceptable alternative in the very difficult decision between terminal insertion of a pyelo-nephrostomy and the strain of a repeated reconstruction operation, especially in patients at high risk for operations or generally.
