Primary Outcome Measures:
  • Bacteriological Response (bacteriuria vs. no bacteriuria) [ Time Frame: 10-14 days after last dose of study med ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Clinical Response (patients without clinical symptoms or signs of bacteriuria vs. patients with clinical symptoms or signs of bacteriuria) [ Time Frame: 10-14 days after last dose of study med. ] [ Designated as safety issue: No ]
  • Incidence of post-procedure GU tract infections other than bacteriuria [ Time Frame: any time after the TRNBP ] [ Designated as safety issue: No ]

Study Start Date: April 2004
Study Completion Date: October 2004
Arms Assigned Interventions
Experimental: Arm 1 Drug: Ciprofloxacin single dose
Patients randomized to this regimen will receive a single-dose of ciprofloxacin MR 1000 mg PO approximately 2 to 3 hours prior to the TRNBP. Patients will also receive two doses of matching placebo approximately 24 hours prior to and approximately 24 hours after the TRNBP.
Experimental: Arm 2 Drug: Ciprofloxacin triple dose
Patients randomized to this regimen will receive three doses of ciprofloxacin MR 1000 mg PO. The doses will be approximately 24 hours prior to the TRNBP, approximately 2 to 3 hours prior to the TRNBP, and approximately 24 hours after the TRNBP.
