Primary Outcome Measures

Name	Time	Method
Main Objective: The primary goal of our study is to evaluate the impact of antibiotic prophylaxis on the rate of bacteriuria, symptomatic UTI, pyelonephritis and urosepsis among patients with sterile urine undergoing SWL. ;Secondary Objective: Secondary goal is to determine pre-procedural characteristics that can define patient subgroups with the greatest benefit from prophylactic antibiotics. ;Primary end point(s): Primary outcome will be a composite endpoint comprised of:<br>•Positive post-SWL urine culture (= 105 CFU/ ml), symptoms of cystitis (defined as new onset burning sensation or pain with voiding, frequency, urgency), or pyelonephritis or urosepsis (hospital admission with fever =38.5 C).<br>;Timepoint(s) of evaluation of this end point: 7-14 days post-SW

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): Our secondary outcomes will be:<br>•Bacteriuria at 7-14 days post-SWL (=105 cfu/ml)<br>•Symptoms of cystitis (new onset burning sensation or pain with voiding, frequency, urgency)<br>•Pyelonephritis or urosepsis (hospital admission with fever =38.5C)<br>•Change in IPSS score at 2 weeks (reported as a numerical value);Timepoint(s) of evaluation of this end point: 7-14 days post-SW
