Trial Purpose

Researchers want to find out if a drug called Cipro® XR (ciprofloxacin extended-release) can help people with a complicated urinary tract infection caused by a kind of bacteria called Pseudomonas aeruginosa. The study doctor will give Cipro XR to some people to see if it is safe and works to treat complicated urinary tract infections caused by Pseudomonas aeruginosa. The study doctor will also gather information about using Cipro XR to treat complicated urinary tract infections caused by other bacteria. About 500 people with complicated urinary tract infections who are 18 years old and older will join this study. Cipro XR is approved by the U.S. Food and Drug Administration (FDA) for the treatment of complicated urinary tract infections and acute uncomplicated pyelonephritis (inflammation of the kidney). The dose of Cipro XR used in this study (1000 mg a day for 7 to 14 days), has been shown to be safe and effective. This study is being done to gather more information on using this dose of Cipro XR for complicated urinary tract infections caused by Pseudomonas aeruginosa, as well as by other bacteria.

Inclusion Criteria

 -- If more than 1 pathogen is identified, each should be present at a colony count >= 100000 CFU/mL (>= 10000 CFU/mL for S. saprophyticus) to be included in the analysis
 -- For catheterized patients two or more pathogens (>= 100000 CFU/mL) (>= 10000 CFU/mL for S. saprophyticus) isolated from a baseline urine culture will be considered contaminants unless simultaneous blood culture yields the same pathogen(s)
 -- The causative pathogen must be susceptible to ciprofloxacin on in vitro susceptibility testing5. Enrollment and start of treatment is permitted prior to the availability of the culture report
