BACKGROUND: There has been a great deal of discussion regarding the necessity of the prophylactic use of antibiotics in transurethral procedures. In order to clarify this complicated issue, a randomized prospective study was performed for patients undergoingurethrocystoscopy or urethrocystography. PATIENTS AND METHODS: Patients who underwenturethrocystoscopy or urethrocystographyand did not have pyuria and bacteriuria were included and divided randomly into 2 groups, either receiving a prophylactic antibiotic or no antibiotic. For antibiotic prophylaxis, 200 mg of sparfloxacin or fleroxacin were administered within a 1-hour period before the urethrocystoscopic or urethrocystographic examination, respectively. Analyses were performed on patients who were seen within 1 month after the examination, using the appearance of pyuria, bacteriuria, or a febrile infection as the endpoint. RESULTS: Of 47 patients undergoing urethrocystoscopy, 45 were eligible for analysis, and of these, sparfloxacin was administered to 21 patients. Thirty-three of 37 patients undergoing urethrocystography were eligible for analysis with fleroxacin administered to 16 patients. There were no significant differences in the background factors between the 2 groups undergoing either transurethral examination. None of the patients in either group developed pyuria, bacteriuria or a febrile infection after the examination. CONCLUSIONS: Prophylactic administration of antibiotics is not necessarily essential in urethrocystoscopy or urethrocystography in patients with sterile urine.
