After many years of persistent writing and discussion on Hunner's part, American urologists have come to believe that stricture of the ureter is a fairly common lesion, and year by year additional case reports have substantiated Hunner's ideas.
Hunner's method of dilating the ureter is by means of wax bulbs molded by hand, and, before the advent of the solid bulb, was the best method available. As all solid bulbs are imported and consequently expensive, I conceived the idea of molding wax bulbs by machine made molds. If one has a set of dies, these bulbs, after a little practice, can be quickly and cheaply made.
When the wax bulb is used for ureteral dilation, the McCarthy cysto-urethroscope is preferable, as it has none of the disadvantages of the female air cystoscope of Kelly, the
