Objectives:
To identify risk factors for sepsis following urinary extracorporeal shock wave lithotripsy (ESWL).
Design:
Retrospective case-control study with two control groups.
Setting:
A rural, 570-bed, regional referral center.
Results:
Six cases (four bacteremias and two fungemias) were compared with two sets of 18 controls. Cases had a higher frequency and number of urinary tract infections prior to the procedure and tended to have larger stone size.
Conclusions:
Patients undergoing ESWL who are at high risk for infectious complications may be identified by preprocedure evaluation. Such patients may require alternative prophylactic regimens and close postprocedure follow-up.
