title: [Clinical experience using polyurethane ureter endoprostheses and studies of the incrustation tendency].
abstract: The advantages of internal urinary drainage by using ureteral splints have often been discussed during the last years. Using this technique in our clinic for 17 years nearly 2000 ureteral splints have been applied in 650 patients. Since 1978, in 164 patients ureteral splints made of polyurethane (PUR) were used. The indications are listed. The complication-rate is very low. Ureteral splints which had been removed after varying periods were examined by scanning electron microscopy. Results of these studies are shown.
