Taking The Guesswork
Out of Ureteral Stent Size Selection
28cm
The current technique when selecting ureteral stent length relies upon a correlation between patient height and anatomy to approximate required stent length.
​
Dr. Larry Lykins has found a solution to this problem, the Lykins Indicator Urological Marker Stylet. Illustrated below are the variations of a standard procedure placing a double J-stent, which the Lykins Indicator seeks to reexamine:
-
Short - Possible loss of stent within ureter, resulting in need to utilize retrieval techniques upon removal
-
Optimal placement
-
Long - Excessive length leading to irritation of bladder
Short
Optimal
Long
The Lykins Indicator Marker Stylet solves this issue by providing visual feedback via cystoscope directly to the physician for determining each patient's specific ureter length. The 0.035"(0.89mm) x 150cm (59.0") hydrophilic coated NiTi stylet with its 5cm tapered tip easily passes through the ureteral orifice and ureter, into the ureteral pelvic junction.
The white, black, and green polymer sections of the stylet, combined with the distal radiopaque marker, designate ureter length and the corresponding stent required. The 22, 24, 26, and 28cm distances, respectively, become apparent as the stylet passes through the ureteral orifice and the radiopaque marker comes to rest in the ureteral pelvic junction.

28cm = proximal black
The Lykins Indicator is the ideal stylet to simplify the task of determining ureteral stent length, based on Dr. Lykins's patent pending visual marker system.
