Management of Ureteral Stent-Associated Spasm

First-Line Treatment Options

The American College of Physicians and other guideline societies recommend NSAIDs as first-line treatment for ureteral spasm due to their ability to decrease ureteral smooth muscle tone and ureteral spasm, with a strength of evidence based on clinical guidelines 1
European Urology guidelines recommend diclofenac, ibuprofen, and other NSAIDs for renal colic and can be applied to stent-related pain, with the recommendation to use the lowest effective dose to minimize cardiovascular and gastrointestinal risks 2

For patients with contraindications to NSAIDs, such as renal insufficiency, GI bleeding risk, or cardiovascular disease, the European Urology guidelines suggest starting with alpha-blockers, with a consideration for individual patient risk factors 2
In cases of severe, refractory pain not responding to medical therapy, early stent removal may be considered if clinically appropriate, based on clinical judgment and patient-specific factors 3

Regular assessment of symptom control and medication side effects is essential, with a recommendation for ongoing monitoring and follow-up to ensure optimal patient outcomes 2
If symptoms worsen despite medical therapy, evaluation for complications such as stent migration, encrustation, or infection is necessary, with consideration for imaging studies such as CT scan if obstruction or perinephric stranding is suspected 2, 3
