Abstract:
[Objective] To compare the clinical efficacy and safety of flexible ureteroscope lithotripsy (FURL) combined with flexible vacuum-assisted urethral access sheath (FV-UAS) and traditional UAS in the treatment of 1-2 cm lower renal calyceal stones, so as to provide reference for clinical practice. [Methods] Clinical data of 157 patients with 1-2 cm lower renal calyceal stones treated with FURL during Mar.2021 and Oct.2023 were retrospectively analyzed, including 80 treated with traditional UAS, and 77 with FV-UAS.General and clinical information of the two groups were compared. [Results] The immediate stone-free rate (SFR) (84.4% vs.67.5%, P=0.013) and final SFR (88.3% vs. 75.0%, P=0.032) of the FV-UAS group were significantly higher than those of the traditional UAS group, with significant difference.The incidence of postoperative complications such as fever, renal colic, and perirenal hematoma was significantly higher in the traditional UAS group than in the FV-UAS group (15.0% vs.5.2%, P=0.042). After treatment with anti-infective and analgesic drugs, both groups were improved, and no severe sepsis or septic shock occurred after surgery.The hospitalization expenses of the FV-UAS group were significantly lower than those of the traditional UAS group [ (18 341±1519)yuan vs.(19 152±1826)yuan, P=0.003]. [Conclusion] Compared to the traditional UAS, the combination of FURL and FV-UAS for the 1-2 cm lower renal calyceal stones has a high SFR and low incidence of complications.Patients experience less pain, recover faster and spend less.It's a new treatment option for inferior calyceal calculi.
