- Some surgeons continue to place ureteral stents in patients undergoing extracorporeal shockwave lithotripsy (ESWL), despite 2 decades of guidelines discouraging this practice.
Why this matters
- A ureteral stent offers "no perceivable advantage" in reducing postoperative emergency department visits or reoperation after ESWL, say researchers.
- Researchers analyzed treatment data from 4 states for patients who underwent ESWL either with or without ureteral stent placement (N=128,040).
- Funding: None disclosed.
- Surgeons performed stent placement during ESWL in 20,800 (16.2%) patients, most commonly in patients who:
- Were older: OR, 1.003 per year (95% CI, 1.002-1.004).
- Had higher comorbidity: OR, 1.10 (95% CI, 1.09-1.11).
- Had higher incomes: OR, 1.13 (95% CI, 1.08-1.19).
- Had private insurance: OR, 1.05 (95% CI, 1.008-1.10).
- Patients who received stents were more likely to visit the emergency department within 30 days after ESWL (8.9% vs 7.3%; P<.0001 or to need reoperation within days of eswl vs p>
- The study was retrospective.
- Specific reasons for stent placement were not available, nor were data on stone sizes, locations, or densities.
