title: Ureteromat. Method to facilitate ureterorenoscopy and avoid dilatation.
abstract: The history of rigid ureterorenoscopy and the development of the Ureteromat are briefly described. The technical principles of the Ureteromat, the technique for its use, and the basic principles for performing ureterorenoscopy aided by this irrigation system are described. In our experience, the average operating time diminished from 66 to 22 minutes with the Ureteromat, severe complications dropped from 4 to 0.9 per cent, and the success rate for calculi in the ureter increased from 72 to 98 per cent. Furthermore, the Ureteromat facilitates other procedures (flexible ureteroscopy and flexible percutaneous nephrolithotomy). No complications ascribable to the Ureteromat were observed.
