The removal of stones from low in the ureter; a report on an improved method.
Extraction of stones from the lower part of the ureter can be facilitated by use of a long filiform which permits the attachment and introduction of dilating Phillips catheters of increasing caliber and of various stone extractors. The filiform must be left in place, with the tip superior to the stone, until the ureter has been successfully dilated, the stone extracted and a drainage catheter inserted. The filiform serves to guide the instruments up the ureter. Smooth muscle relaxation, or "tone paralysis," is achieved by leaving each dilating catheter in the ureter for at least ten minutes.A combination of spinal and local anesthesia is used, and this contributes further to the desired ureteral relaxation. This simple method was used successfully in 34 of 35 consecutive cases to remove a stone in the lower part of the ureter.
