This is a two arm, double blind RCT comparing the use of a single dose ciprofloxacin prior to SWL to saline alone. The multicenter trial will be conducted with a pragmatic emphasis including both high volume and low volume sites internationally.
This is a two arm, double blind randomized controlled trial (RCT) comparing the use of a single dose ciprofloxacin prior to shock wave lithotripsy (SWL) to placebo. The multicenter trial will be conducted with a pragmatic emphasis including both high volume and low volume sites internationally.
Eligibility criteria include patients older than 18 years presenting for SWL who do not meet one of the pre-defined exclusion criteria (outlined below).
Eligible patients will provide written informed consent. Patients will undergo central randomization, which will be accessed by phone or internet. Un-blinding will occur only once statistical analysis is complete.
Patients will undergo SWL using standard procedures at the participating center. Participants will asked to provide a pre-procedure study questionnaire, a modified International Prostate Symptom Score (IPSS) questionnaire and a urine sample for analysis prior to SWL and follow-up. Follow-up questionnaires and a requisition for urine culture will be provided in a pre-stamped, self-addressed envelope along with instructions to return both culture and questionnaires to their participating center at 7-14 days post-SWL. If the follow-up questionnaire has not been received by post-operative day 10 patients will receive a reminder phone call. A second envelope will be sent containing a requisition for urine culture and follow-up questionnaire when necessary.
Alternatively, if a 2 week follow-up is conducted at the participating site then data-forms can be completed and collected at that time. In the event that a urine culture was not submitted 7 days post-operatively, one can be collected up to 14 days post-op. Additional clinical parameters such as presence of double J, stone characteristics and renal insufficiency will be recorded at the time of SWL by the dedicated research staff at the participating center. Data acquisition and occurrence of outcomes will be monitored continuously with scheduled audits.
Primary and secondary outcomes are outlined below.
The power calculation for this protocol was performed using Stata v.10.1 (StataCorp, College Station, TX). The investigators used the American Urological Association Best Practice Statement on antibiotic prophylaxis to estimate a 60% relative risk reduction with treatment arm. Therefore to achieve a power of 90% with a significance level of p<0.05, 661 patients will need to be recruited in each arm for a total of 1,322 patients. Accounting for 10% loss to follow-up, the total required will be 1454, or approximately 1500 patients. Assuming that 25% of patients screened will either refuse to be randomized or will meet one of the pre-defined exclusion criteria, a minimum of 2000 patients will need to be screened in order to randomize 1500 patients.

| Change in International Prostate Symptom Score (IPSS) total score (0-35, higher score indicates worse outcome) | Change in total value of IPSS score will be assessed as a continuous variable with a range from 0-35 with higher scores indicating more severe symptoms. This score is calculated by summation of individual component scores (0-5) across 7 domains | 14 days post-shockwave lithotripsy |
