Types of Catheters

Straight Catheter

• Single lumen with small open.

• Urine drains from the tip, through the lumen and into the receptacle.

• Can be performed by the patient.

• Common in patient who have incomplete bladder emptying:

  • Neurogenic conditions

  • Post anesthetic

  • Post-op certain urinary surgeries or vaginal hysterectomy

• To obtain sterile sample “in and out”

Indwelling or “Foley” Catheter

• Retained for longer periods of time.

• Retained by small balloon which anchors it against the bladder neck.

Coude Tip

• Male patient with an enlarged prostate which obstructs the urethra.

• Less traumatic during insertion.

• Stiffer and easier to control.

• Maintain unobstructed flow

• Bag below level of bladder

• Separate measuring receptacle for each patient

• Routine peri-care.
