Resectoscope sheath obturator-follower
RESECTOSCOPE
SHEATH OBTURATOR-FOLLOWER

During transurethral surgery the urethra is dilated with metal sounds before introducing a suitable resectoscope sheath. When a stricture, diverticulum, or irregular urethra impedes the passage of the sound, a filiform is manipulated through the urethra, followed by followers of
converting the obturator into an obturatorfollower. After dilating the urethra with filiform and followers, the follower is detached, leaving the filiform in the urethra. The resectoscope sheath with its obturator-follower is screwed to the

varying sizes. At times, when follower and filiform are withdrawn, an attempt to introduce the resectoscope sheath fails. A simple modification of the resectoscope sheath obturator has proved valuable in overcoming the occasional failure and is described here. An adaptation of the Council1 stylet, it is made by fitting a threaded end to the top of an obturator. The end of a metal follower is sawn off approximately 3 mm. proximal to the threaded tip. A 3-mm. hole is drilled in the tip of the obturator. The threaded follower tip is soldered in the hole,

filiform and follows it through the urethra and into the bladder with minimum trauma to the urethra. The obturator-follower is then withdrawn with the attached filiform, leaving the resectoscope sheath in place ready to receive the working element of the resectoscope (Fig. 1). The obturator-follower, made in our hospital workshop, should stimulate its manufacture by commercial instrument makers. The principle may be applied to any obturator that reaches the tip of a cystoscope, such as the panendoscope. Beirut, Lebanon ACKNOWLEDGMENT.
