Flexible ureteroscopy
Unlike traditional rigid sheaths, FANS features a deflectable tip that can be guided into specific calyces, allowing for synchronized suction and active fragment evacuation. Conversely, Direct In-Scope Suction (DISS) utilizes a sheathless approach, where suction is integrated directly into the ureteroscope. While DISS avoids potential ureteral trauma associated with access sheaths, FANS is often associated with shorter operative times due to its superior irrigation-aspiration efficiency
