Abstract
Cystourethroscopy is today becoming an important means of diagnosis of lower urinary tract disorders; through direct visualization of its anatomy and macroscopic pathology. Although cystoscopy has now become a common, safe and well tolerated out – patient urologic procedure, significant infectious complications as bacteremia,bacteriuria,oxacerbation of lower U.T.I and acute pyelonephritis may follow. The problems of infection and its control confronting the endoscopist are as great as ever before and even greater than during the pre- antibiotic era. This owes to change in patterns of infection in the hospital community, the dilema of antibiotic resistant strains of bacteria and may be due to the rising number of therapeutic and diagnostic endoscopic maneuvers performed daily. The present study aimed at determining the rate of UTI following diagnostic urologic endoscopic procedures and detecting the possible predisposing factors of post endoscopic UTI. 200 patients undergoing diagnostic cystoscopy or cystoscopy with minimal intervention at Alexandria Main University Hospital [Urology Department and out-patient clinic] and at a private hospital were involved in this work. A full relevant information sheet was fulfilled for each of them. Pre-cystoscopic urine samples were collected from all patients and follow–up post–cystoscopic ones were collected from the 123 patients who attended for follow-up within one week. Smears were taken from the cystoscope before and after introduction into each patient. On 63 occasions, samples were collected from Cidex basin, rinsing water basin, irrigation fluid (Glycine 1.5) and from the content of lubricant gel tube). All urine samples were subjected to direct microscopic examination, quantitative and qualitative culture on CLED, blood and Mac Conckey agar. Overnight incubation at 37oC under aerobic conditions was followed by full identification of isolates according to methods described by Bailey and Scott’s. The identified isolates were subjected to antibiotic susceptibility test described by Kirby and Bauer. Samples from Cidex, rinsing water, glycine, lubricant gel and from the cystoscope were all cultured on blood and Mac Conkey agar. After overnight incubation at 37oC aerobically, isolates were fully identified.
