For the introduction of various medicinal substances into the urethra I have devised, and have been employing for some time, a series of tubes modeled after the pattern of the Ultzmann instillation syringe. These tubes are made of sterling silver, and range in size from 14 F. to 24 F. In shape they follow the curve of the classical urethral sound, and all have capped ends with threads suitable for the attachment of the universal hypodermic syringe. By means of adaptors they can readily be adjusted to fit all glass and record syringes.
There is also a sound handle, which is likewise adjustable, so that each tube can easily be converted into a urethral sound. In addition, another attachment is supplied in the way of a short silver tube, much like the ordinary glass irrigating nozzle, but having an adjustable small end for attachment to the tubes, to be used
