Simplified ureteral stent placement with the assistance of a ureteral access sheath.

Journal Article (Journal Article)

PURPOSE: When using a ureteral access sheath following a ureteroscopic procedure, placement of an internal ureteral stent can be simplified by inserting the stent through the sheath without the need to reinsert the cystoscope. MATERIALS AND METHODS: An indwelling ureteral stent with the pull string attached is inserted over the guide wire into the access sheath followed by the pusher. The guide wire is partially withdrawn allowing the stent to form a coil in the renal pelvis, using the pull string to adjust the stent position. The fluoroscopy unit is then focused onto the bladder and the guide wire is slowly withdrawn until its tip is at the level of pubic symphysis. The pusher and guide wire are then removed and the pull string is cut at the urethral meatus. RESULTS: Among 71 cases studied 60 required ureteral stent placement. In 43 of the 60 cases (72%) the ureteral access sheath greatly facilitated ureteroscopy, and a stent was placed through the access sheath in 34 (79%). Stent placement through the access sheath was successful in all cases, with an average time saving of 2.3 minutes per case, compared to placing the stent by reinserting a cystoscope. CONCLUSIONS: If an access sheath has already been placed during a ureteroscopic procedure and stent insertion is deemed necessary, the stent can be easily placed through the access sheath under fluoroscopic guidance without the need to reinsert the cystoscope. Our experience suggests that all urologists who routinely perform ureteroscopic procedures can easily master this timesaving technique.
