Technique, minimal requirements and fragmentation strategies in RIRS.

Flexible ureteroscopy is a highly resolving surgery which is able to solve most renal lithiasis of any Urology Department, with very low economic impact. It is a technique that has helped to continue treatment when SWL couldn't, and also has reduced the number of percutaneous renal surgeries that we currently perform. In this paper, we try review three important features of the operation: Technique, minimal requirements that we need to perform this surgery in a Urology Department, and the different possibilities to treat the lithiasis with holmium laser. We want to show how to perform the surgery successfully and advise what instruments and other surgical materials we really need to purchase. It is totally proved that this is a minimal invasive technique, with reasonably low cost and highly effective.
