简要总结
Retrograde intrarenal surgery (RIRC) is used as standard treatment for stones less than 2 cm. In some cases, the ureteral access sheath cannot be placed due to ureteral stricture. In this case, a double j stent (DJ) is placed to passively dilate the ureter, and the RIRC is postponed for post-dilatation. The aim of the study is to determine the optimal time for RIRC operation in cases where a double j stent was placed for passive dilatation.
