The technique of the "our renal stone extraction" in elastic impression material clods is described. This coagulum theoretically incorporated within itself all free calculi or fragments regardless of size or location. They are removed on withdrawal of the perfect mold of the pelvic cavity through the intrarenal pyelotomy incision. The main points are as follow: l)The substance is injected into the renal pelvis by standard techniques, coagulates are formed uniformly and completely within a short period of time and visualized by X-ray films. 2)The properties of the elastic impression materials (Surflex F and Flexicon) are chemically and physically inert, non-allergenic and non-carcinogenic, cause no foreign body reaction, and are easily sterilized. 3)After the intrarenal pyelolithotripsy, large stones are removed with forceps and undemonstrable fragments are easily removed without any trauma of the renal parenchym. 4)The elastic impression materials are very cheap and easily obtained. This method has been utilized in the renal stone extraction on 5 cases of artifical renal stones and two patients with a staghorn calculus. The results were excellent.
