1. A device for the dissolution of urinary calculi in patients affected by urinary calculosis, comprising:

  • a tubular sleeve adapted for insertion in a urinary cavity of a patient; and

    two or more electrodes connectable to a source of electricity so as to form an electrolytic circuit for electrolytic calculus dissolution;

    said two or more electrodes comprising at least one slideable electrode which is slidably accommodated inside said tubular sleeve between;

    a first position in which said at least one slideable electrode is substantially completely accommodated inside said tubular sleeve for facilitating the insertion of the tubular sleeve inside the urinary cavity of the patient; and

    a second position in which said at least one slideable electrode protrudes outside of said tubular sleeve once said tubular sleeve has been inserted inside the urinary cavity of the patient for making contact with a calculus located in the urinary cavity of the patient for electrolytic dissolution of the calculus upon formation of said electrolytic circuit of said two or more electrodes.
