Overview
Comparison of routine postoperative stenting versus no stenting after ureterorenoscopy for ureteral stones to assess the necessity and impact on complication risk.
Description
After a ureteroscopy (URS) for the removal of ureteral stones, a double-J stent is routinely placed. Among other measures, this is intended to prevent pain caused by ureteral swelling, small residual fragments, blood clots, and potential drainage obstructions, which could lead to colic or fever. However, the evidence supporting the benefit of this practice is limited. At the same time, many patients report discomfort due to the stent (e.g., flank pain, dysuria, frequent urination, hematuria), which can significantly impact their quality of life.
