Evaluating Postoperative Pain After Ureterorenoscopy.

Prospective Randomized Study on the Necessity of Postoperative Stenting After Ureteroscopy (URS) for Ureteral Stones.

Comparison of routine postoperative stenting versus no stenting after ureterorenoscopy for ureteral stones to assess the necessity and impact on complication risk.

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.

Inclusion Criteria:

• Age 18 years or older
• Patients with ureteral stones scheduled for ureteroscopy (URS) and stone removal
• Previous pre-stenting
• Informed Consent as documented

Exclusion Criteria:

• Complex ureteral conditions (e.g., known ureteral strictures)
• Impacted stones
• Solitary kidney
• Patients with significant renal stones (>3mm)
• Previous ureteral surgeries (except endoscopic stone treatments)
• Pregnancy or suspected pregnancy
