A Multicenter Randomized Controlled Trial of Antimicrobial Prophylaxis to Prevent Urinary Tract Infections after Shockwave Lithotripsy for Urolithiasis: The APPEAL Trial

A single dose of ciprofloxacin reduced the risk of post-SWL pyelonephritis, with a modest absolute benefit. The patient importance of this reduction depends on individual preferences in weighing a small absolute reduction in risk against the potential harms and resistance-related implications of antibiotic use. Results from the APPEAL trial will inform global practice and support evidence-based decision-making for patients undergoing SWL.
