Modified telescopic sheath method for exchange of luminally encrusted ureteral stents.

ABSTRACT

A novel telescopic access sheath technique has been described to maintain access to the ureter in cases of stent encrustation, placing a suture on the externalised distal end of the stent followed by advancing a sheath over to peel off encrustations and maintain access in the ureter, as well as application of this technique in a child. Herein we present a modification of the telescopic sheath technique that allows exchange of luminally encrusted stents without requiring passage of the sheath into the ureter or ureteroscopy alongside the stent.
