title: Extracorporeal shock wave lithotripsy. Use of antibiotics to avoid postprocedural infection.
abstract: Extracorporeal shock wave lithotripsy (ESWL) has the potential to revolutionize the treatment of urolithiasis, but its success depends in part upon minimizing potential sequelae. Although ESWL is safe, effective, and relatively economical, one complication can be urosepsis, resulting from liberation of bacteria when the stones disintegrate. Patients who are at increased risk of infection are those who have existing urinary tract infection; perioperative urologic manipulation; infected stones; predisposition for infectious endocarditis; or multiple, large, or complex stones. If urosepsis occurs, it usually requires prolonged hospitalization, which obviates any cost-benefits that can be accrued from ESWL. Prophylactic use of an antibiotic before ESWL is rational and cost-effective. Ideally, the antibiotic should possess a spectrum of activity against the most likely bacteria to be encountered, require a limited number of doses, and offer the flexibility of sustained coverage in the event that the procedure is delayed. Our experience at Presbyterian Hospital of Dallas supports the use of a long-acting cephalosporin for the prevention of infections following ESWL.
