About this study

Urinary calculus is a globally recognized urological condition, with prevalence rates ranging from 1% to 13% across different geographical regions (1) Therapeutic approaches for renal calculi encompass extracorporeal shock wave lithotripsy (ESWL) and minimally invasive endoscopic surgical techniques, such as percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). Treatment plans depend on the characteristics of calculi, patient factors, surgeon experience and the condition of medical centers. According to the guidelines of American Urologic Association (AUA) and European Association of Urology (EAU), patients with a burden of less than 20 mm in kidney calculi can choose RIRS as the frst-line surgical treatment with good stone-free rate (SFR). (2, 3) The application of RIRS for urinary stones has increased signifcantly, and the indications have expanded due to developments in minimally invasive technology and equipment. (4) With the development of stone retrieval devices and miniaturized fexible ureteroscopes, RIRS is more widely used for treating renal calculi, even for high burden stones. (5, 6) The application of ureteral access sheath (UAS) in RIRS can improve surgical vision, reduce intrarenal pressure (IRP), and decrease postoperative infectious complications. (7-9) Several reports have demonstrated the superiority of suctioning UAS, including shorter operation time, higher SFR and lower incidence of infectious complications compared with traditiona…
