A new spin on the entrapped ureteral calculus.
We describe ureteroscopic lithotripsy using a revolving 1.5F tipless basket. After passing a laser fiber alongside the basket and performing lithotripsy, one uses a rotary wheel at the base of the basket handle to spin the stone to a different area for further fragmentation. This allows complete stone fragmentation, in contrast to traditional laser baskets, which bore a hole through the center of the stone. Irrigation flow testing demonstrated significant advantages with the 1.5F basket with or without a laser fiber alongside the basket compared with traditional baskets.
