What type of devices facilitate the elimination of urine?

Answer

Elimination is a basic human function of excreting waste through the bowel and urinary system.  The process of elimination depends on many variables and intricate processes that occur within the body.  Urinary catheterization is the insertion of a catheter tube into the urethral opening and placing it in the neck of the urinary bladder to drain urine.  There are several types of urinary elimination devices, such as indwelling catheters, intermittent catheters, suprapubic catheters, and external devices.  An indwelling catheter, often referred to as a "Foley catheter," refers to a urinary catheter that remains in place after insertion into the bladder for continual collection of urine.  It has a balloon on the insertion tip to maintain placement in the neck of the bladder.  The other end of the catheter is attached to a drainage bag for the collection of urine.

There are two common types of bags that may be attached to an indwelling catheter.  During inpatient or long-term care, larger collection bags that can hold up to 2 liters of fluid are used.  These bags should be emptied when they are half to two-thirds filled to prevent traction on the urethra from the bag.  Additionally, the collection bag should always be placed below the level of the patient's bladder so that urine flows out of the bladder and urine does not inadvertently flow back into the bladder.  A second type of urine collection bag is a leg bag.  Leg bags provide discretion when the patient is in public because they can be worn under clothing.  However, leg bags are small and must be emptied more frequently than those used during inpatient care.  

Irrigation catheters are typically used after prostate surgery to flush the surgical area.  These catheters are larger in size to allow for larger amounts of fluid to flush.  

Suprapubic catheters are surgically inserted through the abdominal wall into the bladder.  This type of catheter is typically inserted when there is a blockage within the urethra that does not allow the use of a straight or indwelling catheter.  Suprapubic catheters may be used for a short period of time for acute medical conditions or may be used permanently for chronic conditions.  

A condom catheter is a noninvasive device used for males with incontinence.  It is placed over the penis and connected to a drainage bag.  This device protects and promotes healing of the skin around the perineal area and inner legs and is used as an alternative to an indwelling urinary catheter.
