title: [Echo-assisted percutaneous nephrolithotomy in the supine position. Technical notes].
abstract: The adoption of supine position in percutaneous nephrolithotomy and the routine use of echography during the procedure allow for a reduction of surgical time, radiological exposure of patient and surgeons, and of anaesthesiological risks; moreover, it permits a combined anterograde-retrograde approach to the kidney in case of very complex lithiasis. The urologist's knowledge and experience of echography devices allows for a high lowering of the learning curve time.
