The new stent removing snare is designed to streamline indwelling ureteral stent removal in the office, with new access, increased convenience and minimal anesthesia. The design’s goal is ease of use and minimizing set-up time and patient discomfort by eliminating the cystoscopy. The 18 F snare is designed to work best in the male urethra. The snare should not be advanced beyond the bulbous urethra. The snare is also available in a smaller size 16 F, which works better removing a stent from the female bladder, as it may require more manipulation.
The Stent Removing Snare allows for the non-visual removal of indwelling ureteral stents, without the use of cystoscopy. The instrument is designed to be passed over a guide wire if clinically needed.
Method of UseClick to Expand
Men (18F Snare should be used) – When the ureteral stent is inserted, the attached string should be left connected to the stent and a 2 cm diameter loop should be created in the string at the point where the string exits the urethra (see figure 1). The loop can be locked in place by placing several knots.
The snare enters the bladder and is directed towards the side of the stent. A finger in the vagina can help with localization of the snare and the stent itself. The snare may grab the stent itself or one of the string loops. If the stent itself is engaged, a proprioceptive feedback tug will be felt. If the snare misses, repeat passes can be made. Cystoscopic removal is the fallback option.

The design of the snare has a conical appearance with increasing size between 16-18 F. The snare element at the base of the cone is a groove 3 mm wide, which can hook the stent or the string attached to it. The design of the head allows for non-traumatic travel through the urethra. This conical configuration also allows this instrument to be used as a dilator, when passed over a guide wire, as a way to avoid a false passage with blind dilatation.
