Catheter Selection
Consider:
• Reason for catheterisation
• Time catheter to remain in situ
• Appearance of urine
• Sex of patient
• Will dictate - size, length, material & type
of catheter
![Page 12: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/12.jpg)
Catheter Selection
Materials:
Short term (up to 7 days)
• PVC (plastic)
• Plain latex
• Silicone treated
![Page 13: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/13.jpg)
Catheter Selection
Materials:
Medium term (up to 28 days)
• Teflon (PTFE) coated
smoother than plain latex
lessens irritation to urethral mucosa
coating lessens absorption of water by
latex
![Page 14: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/14.jpg)
Catheter Selection
Materials:
Long term (up to 12 weeks)
• hydrogel coated
• silicone elastomer coated
• 100% silicone
• Silver coated
• Antibiotic impregnated
![Page 15: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/15.jpg)
Catheter Selection
Guage:
• FG or CH
• One Charriere (CH or FG) unit =
1/3mm, so that a 12CH is 4.0mm in
diameter.
• select smallest size that will drain
adequately
• large bore causes urethral
irritation/damage
• bypassing - smaller NOT larger gauge
![Page 16: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/16.jpg)

![Page 21: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/21.jpg)
Asymptomatic bacteriuria v CAUTI
• Bacteriuria (presence of ≥105 bacteria/ml in absence of symptoms) is not the same as UTI.
• Prevalence of asymptomatic bacteriuria with short-term(<7days) catheterisation is 10-20% but symptomatic UTI develops in only 2-6%
• In patients’ catheterised long term (>30days), prevalence of bacteriuria is almost 100%
• Bacteraemia, most commonly Gram-negative, develops in 1-4% of patients with UTI and has a mortality of 13-30%
• Symptomatic bacteriuria or CAUTI is characterised by≥ 2 symptoms of UTI i.e. fever (temp >38•C), dysuria, urgency, frequency, new incontinence, supra pubic tenderness, loin pain, and change in cognitive status.
• ONLY TREAT SYMPTOMATIC BATERIURIA
![Page 22: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/22.jpg)
Bladder
UTI
• Causative factors

![Page 44: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/44.jpg)
Supra-pubic catheterisation
• Catheter is inserted directly into the bladder via
the anterior abdominal wall
• First introduction currently always carried out by
Urologist or Urology Nurse Practitioner (local or
general anaesthetic)
• Only instance when a large bore foley catheter
is used long term
• Can be changed by nurse as soon as first
routine change (> 2 weeks since insertion)
![Page 45: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/45.jpg)
Supra Pubic - suitable for:
• Those experiencing problems related to urethral
catheters
• Disorders of the genitalia
• Surgical or acquired urethral closure/trauma/ stricture
• Sexually active patients
• TWOC - catheter can be clamped rather than removed
• Long term disability (especially female)
• ANY age group
![Page 46: Catheter Management in the Community - Primary Care … · Catheter Management in the Community Fiona Sexton, RN, BSc, SPQ, MSc Urology Nurse Specialist President BAUN](https://reader030.fdocuments.in/reader030/viewer/2022040622/5d2d6eb288c99351148c0d92/html5/thumbnails/46.jpg)
Supra Pubic catheterisation
