The document discusses catheters and catheterization. It defines a catheter as a thin, flexible tube inserted into the body for draining fluids or injecting substances. The main types of catheters discussed are Foley catheters, red rubber catheters, and Malecot catheters. Common indications for urethral catheterization include urine retention, neurogenic bladder, and before certain surgeries. The methodology section outlines best practices for catheter insertion including using aseptic technique, lubrication, and inflating the balloon once in the bladder. Complications from catheterization can include urinary tract infections if asepsis is not followed.

3. What is catheter ?
(मूत्र ननस्सारक नली ) ?
The word catheter (Gr. Katheter ) means “something inserted.”
“A tube passed into the body for evacuating fluids or injecting them into body
cavities. It may be made of elastic, elastic web, rubber, glass, metal or plastic”.
(Taber’s Medical Dictionary)

Catheters are thin flexible tubes
Soft hollow tube
Inserting into urinary bladder to
drain urine
CATHETERIZATION
“Passage of a catheter into a body
canal or a cavity”

•Gibbon’s Catheter
• For male & female (have 2 different size)
• Made of plastic, gives rigidity to catheter, aids it passage
• Its 2 ribbons fix it to genitalia
• Lesser irritant to urethra

•Malecot’s Catheter
• Self retaining,
• Red rubber tube like
• Tip bulbous/winged
• Stretched the bulb & inserted inopening that having narrow os
than catheter bulbous tip.
• Use – for drainage in Suprapubic cystostomy, gastrostomies,
cholecystostomies, thoracotomy, close drainage of any cavity

14. Indication of Urethral Catheterization
22-09-2020Catheter & catheterization- Dr Mahesh Kumar 14
 Urine retention- Acute & chronic
 Chronic retention of urine with overflow.
 Urethral stricture
 Urinary incontinence/unable to hold urine
 Neurogenic bladder.
 Before major surgery
 Surgery related with UB & prostate
 Patient going to pelvic surgery
 Patient going to perineal surgery
 For Managemnt of incomplete urethral rupture
 GeneralAnaethesia

To drain urine from UB

15. Indication of Urethral Catheterization
Medical conditions- Bed ridden patient, Commatous patient, spinalcord injury, multiple
sclerosis, dementia.

When wants to measure urine output e.g. in Acute renal failure(ARF).
For urography/cystography investigations
To measure residual urine, bladder capacity, urodynamic

To drain urine from UB

16. Method of Catheterization
Be careful
- First of all find actual indication
- Selection of catheter depends on situation in patients, temporary(plain) or for long
time being (Foley, Gibbon),
- Size of catheter chosen on – size of external meatus of urethra, or by own
experience/hit & trial base. On basis of male, female, childhood,
adult.
- Check the balloon of Foley catheter before insertion,
22-09-2020Catheter & catheterization- Dr Mahesh Kumar 16

17. Method of Catheterization
22-09-2020Catheter & catheterization- Dr Mahesh Kumar 17
Be careful
- Always follow aseptic measures as chances of introducing urinary
tract infection during catheterization
- Use with general rule “ NOTOUCHTECHNIQUE”.Take
assistance from staff.

18. Material required
22-09-2020Catheter & catheterization- Dr Mahesh Kumar 18
Antiseptic solution
Catheter
Surgical gloves of
appropriate size
Anaesthetic &
lubricating agent
Lignoacine jelly
Dressing material -Cut
sheet, cotton, gauze
piece
Clean area/ space-
Minor OT
One Assistance

19. Methodology
• Clean the local part/ external genitalia with antiseptics
• Draped the patient, only local part exposed
• Clean skin of penis, retract foreskin/prepuce/clean smegma gently
• Push lignocaine jelly 10 ml in penis, close the meatus, gentle rub on undersurface
of penis towards root, wait for a minute.
• Lubricate catheter and insert in urethra gently (hold the penis erect)
• Don’t force, if there is no obstruction it, passes smoothly.
• The urine came from catheter when it reached to UB, push the catheter down and
then start to inflate the bulb of catheter with saline/water.
• Attach the catheter to UROBAG/close container.

20. Complication of Urinary Catheterization
• SOME OTHER
• Burning sensation at urethral
• Fever, with /without Chills, rigours
• Headache
• Pus in urine/cloudy urine
• Foul smelling of urine.
• Urine leakage /from side of catheter
• hematuria
22-09-2020Catheter & catheterization- Dr Mahesh Kumar 20
Serious complication
• Urethral Haemorrhage/Bleeding
• False tract
• Infection (Ascending, iatrogenic)
