The combination of FANS-UAS and FURL is a safe and effective method for treating upper urinary tract infectious stones. Its advantages include a higher immediate stone-free rate, lower hospitalization costs, reduced need for postoperative adjuvant therapy, a lower incidence of sepsis, and faster postoperative recovery, while achieving a long-term stone-free rate comparable to FURL alone. This approach represents a viable new treatment option.
