Use of the one-stick introducer system set in the pyelostomy as a 1st stage of pyelo-uretero-lithotripsy (PUL)

In the last few years there has been an increasing diffusion of endoscopic percutaneous trans-lumbar lithotripsy as a treatment for kidney stones. This technique requires an adequate pyelostomic approach. The authors at this purpose suggest the utilisation of the "One Stick Introducer System Set", that has been created for the biliary tree catheterism as this set is easy to use and rarely traumatic for the patient.
