[Interventional sonography after kidney transplantation]

In cases of urinary fistulae as well as lymphoceles the only ultrasound-guided percutaneous nephrostomy has led to a good result. In cases of ureterostenosis and distal fistulae the renal function could be preserved by percutaneous nephrostomy. The anterograde pyelography was exact in demonstrating localization of the stenosis which led to a better operative procedure. The interventional ultrasound therefore represents an important option in the treatment of operative complications after kidney transplantation.
