3 도뇨관의역사 Painful urinary retention 은기원전 3000 년에도있었다. 당시사용한것들 : straw, rolled up palm leaves, hollow tops of onions, as well as, gold, silver, copper, brass, and lead 11 세기 : 굽혀지는금속 catheter, 주로굽히기쉬운은제품 18 세기고무로만든 catheter ; 너무열에약함, Debris Latex rubber 제품 : 1935 년 www. URO Today.com

4 Frederic E.B. Foley( ) St. Paul urologist introduced the latex balloon catheter at a urologic meeting in 1935 Foley type catheter (0.33 mm = 1 French [Fr]) 초창기에는 male penis, female labia 에묶거나고정

5 Foley type urinary catheter

6 Catheter fever Open drainage system The urinary catheter was originally an open system with the urethral tube draining into an open container

7 Closed drainage system 1950 년대이후 closed bag 도입

8 다른방법들 생각해봅시다.

9 Bladder irrigation: 방광세척 여러가지로씻어보기 Normal saline KMNO4 Antibiotics Povidone iodine Prophylactic bladder irrigations using antibiotics, hydrogen peroxide or povidone-iodine are not helpful. J Hosp Infect. 1992;21:223 9, N Engl J Med. Colonization or infection with more resistant organisms.

10 요도구를매일소독해주기 Routine daily meatal care 혼합항생제크림 : Infect Control Hosp Epidemiol Mar;12(3): % Betadine meatal care vs no care: 간호학회지 1989 chlorhexidine gluconate or povidone iodine: J Hosp Infect 2004 Mar;56(3):236-8 meatal disinfectants and antibacterial urethral lubricants are ineffective no benefits with routine daily periurethral cleaning using normal saline, soap, or an antiseptic or with the addition of antiseptics to the drainage bag

11 정기적으로교체해주기 7 일 14 일 21 일 28 일 There are no strong recommendations to date as to the time at which routine catheter changes have to be made. Most guidelines agree that catheters should not be changed routinely. Some advocate change if there is presence of obstruction, before urine sampling for culture or before treatment initiation for symptomatic UTI.

12 특별한카테터 Silver coated catheter Antibiotic coated catheter Antibiotic-coated catheters have been shown to prevent or delay the onset of catheter-associated bacteriuria. However, there is no evidence to suggest that they decrease symptomatic infection or demonstrate any clinical benefit. Nitrofurazone-impregnated catheters had significant effect on biofilm formation and bacterial growth. In the former, this was significant for only the initial 5 days of catheterization.

13 14 일이내사용하는경우 Types of indwelling urethral catheters for short-term catheterization in hospitalized adults. Cochrane Database Syst Rev Silver alloy-coated catheters were not associated with a statistically significant reduction in symptomatic CAUTI, and are considerably more expensive. Nitrofurazone-impregnated catheters reduced the risk of symptomatic CAUTI and bacteriuria, although the magnitude of reduction was low and hence may not be clinically important. However, they are more expensive than standard catheters. They are also more likely to cause discomfort than standard catheters.
