Introduction & Objectives: Post-traumatic urethral strictures are usually accompanied by infections of the lower urinary tract. The development of infection of the prostate in urethral strictures remains unclear. Our research is geared towards the study of the infectious factor of the prostate before urethral stricture surgery. Material & Methods: We studied 60 patients between the ages of 28 and 45 years with post traumatic urethral strictures prospectively. We carried out bacteriological analysis of the urine of all subjects, prostatic secretion (EPS) of 40 men and we performed transrectal biopsy (PB) for the remaining 20 patients with obliteration of the urethra for bacteriological investigations before surgery. Results: In all cases we isolated bacterial pathogens from urine, EPS and PB. The average level of bacteriuria was 106 colony forming units (CFU)/ml. Infectivity of the EPS and PB was CFU 104 /ml in both cases. In the urine and PB enterobactereacae LQFOXGLQJ(VFKHULFKLDVSSSUHGRPLQDWHGEXWLQWKH(36ದJUDPSRVLWLYHᚐRUD1RQ clostridial anaerobes (Propionibacterium sp., Peptostretococcus species) were seen PRUHIUHTXHQWO\ S LQ3%  DQG(36  FRPSDUHGWRXULQH   %DFWHULDOPL[HGLQIHFWLRQZDVVHHQLQRIFDVHVLQWKHXULQHRI(36 and 80% of PB.

1009 MULTI-RESISTANT PSEUDOMONAS AERUGINOSA OUTBREAK IN AN ENDOUROLOGY UNIT Dasgupta R., French G., Glass J.M. Guys Hospital, Dept. of Urology, London, United Kingdom Introduction & Objectives: There has been recent interest in the emergence of antibiotic resistance, which can have disastrous consequences for a high turnover specialty such as endourology. In our tertiary referral unit, which performed over 750 ureteroscopies in a 12 months period, we describe an outbreak of multiresistant Pseudomonas aeruginosa which infected 19 patients and caused one death. The control of such an outbreak and subsequent monitoring of infected individuals is of paramount importance, particularly in the context of a virulent organism that is resistant to common antibiotics. Material & Methods: We review the fate of 19 individuals who developed LGHQWLFDOVWUDLQFLSURᚐR[DFLQDQGJHQWDPLFLQUHVLVWDQW3VHXGRPRQDVDHUXJLQRVD urosepsis, with 24-month microbiological and radiological follow-up.
