It is almost impossible to extract all the stone fragments from the renal collecting system during retrograde intrarenal surgery (RIRS) [1]. The process of self-elimination is a timeconsuming process that may cause renal colic, residual stone fragments may cause haematuria in the process of selfelimination [2]. Usually, a ureteric access sheath (UAS) is placed under the pelvi-ureteric junction (PUJ) in RIRS [3]. This causes the irrigation fluid in the kidney to pass through the PUJ to enter the UAS. The PUJ is relatively narrow and acts as a functional valve between the renal pelvis and proximal ureter [3].
