[Evaluation bacteriological analysis of urine in patients with long-term bladder drainage].

INTRODUCTION: The experience of comparative evaluation of the effectiveness of various types of urethral catheters in prevention of catheter-associated infection is described in this article. MATERIALS AND METHODS: The study included 69 patients treated at the CCH n.a. S.I. Spasokukotsky in the period from December 2017 to March 2018. The average age of patients was 67.5 years. In all patients, the bladder was drained by a two-way Foley catheter No. 16-18 Ch (100% silicone). In the 1st group (n=18), the bladder was drained with a standard urethral uncoated catheter, in the 2nd (n=16) - with a silver impregnated urethral catheter, in the 3rd (n=15) - with an urethral catheter coated with nitrofuran, in the 4th (n=20) urethral catheter with the possibility of controlled irrigation of the bladder and urethra with antiseptic solutions and (a new model of the urethral catheter developed during cooperative work of the Moscow State University of Medicine and Dentistry n.a. A.I. Evdokimov Urology Department and National Medical Research Center of Obstetrics, Gynecology and Perinatology n.a. V.I. Kulakov). RESULTS: The bladder was drained by Foley urethral catheter for more or equal 15 days. A microbiological study of urine (on the example of clinical isolates of conditionally pathogenic microorganisms) with preparation of an inoculum, inoculation of nutrient media, counting cultures of pathogenic bacteria and determining the sensitivity of pathogenic bacteria to antibiotics was carried out. The study showed the effectiveness of the new urethral catheter model in patients with long-term bladder drainage. CONCLUSIONS: Conducting multicenter studies evaluating the effectiveness of the proposed urethral catheter model with the inclusion of a larger number of patients will reduce the economic costs, associated with treating patients with prolonged bladder drainage in the long term by reducing the number of nosocomial infection cases and reducing postoperative day.

RELEVANCE: and goals. The evaluation of the results of the primary introduction into clinical practice of two new models of the urethral catheter. Considering the advisability was evaluated the efficiency of using new models of urinary catheter for the prevention and treatment of postoperative complications after radical prostatectomy, as well as in the treatment of major pathological conditions accompanied by the infectious-inflammatory complications MATERIALS AND METHODS: The study included 25 patients who underwent radical prostatectomy (the first group) or transurethral resection of the bladder / prostate (the second group). After surgery, the bladder was installed specially designed urethral catheter with controlled filling the balloon is located in the area formed by the anastomosis (the first group) and urinary catheter irrigation urethra drugs (the second group). In the control group (n=22) in the bladder has been established a standard two-way silicone Foley urinary catheter. RESULTS: Hypersensitive of the new model of the urethral catheter none of the patients were observed. The average period when the urinary catheter in the main and control groups, exactly as the incidence of dysuria did not differ. After removal of the urethral catheter in all patients in the study and control groups restored self urination. CONCLUSIONS: The preliminary data showed a good tolerability the new models of the urethral catheter. Evaluation of the effectiveness of distant occupy additional time and will require inclusion in the study a larger number of patients.
