Experimental study with the Scurasil ureteral prosthesis.

The latest generation of Scurasil (dimethylpolisoxane) ureteral prosthesis was used in six dogs as a model for internal urinary diversion in patients with metastatic disease. It was found to cause minimal reaction but carried a high complication rate, including stone formation, end-stage pyelonephritis, and hydronephrosis. Although technically easy to use, modifications in design are necessary prior to use in humans.
