Urinary Diversion
You do not need
to have a bladder in order to live, but it is critical to
maintain an uninterrupted flow of urine from the body. Fortunately,
this flow can be accomplished with a urinary diversion.
What happens
under normal conditions?
The urinary tract is similar to a plumbing system, with special
pipes that allow water and salts to flow through them. The
urinary tract includes the kidneys, two ureters, the bladder
and the urethra.
The kidneys act
as a filter system for the blood, cleansing it of poisonous
materials and retaining valuable glucose, salts and minerals.
Urine, the waste product of the filtration, is produced in
the kidneys and trickles down 24 hours a day through two 10-
to 12-inch long tubes, called ureters, which connect the kidneys
to the bladder. The ureters are about one-fourth of an inch
in diameter, and their muscular walls contract to make waves
of movement to force the urine into the bladder. The bladder
is expandable and stores the urine until it can be conveniently
disposed of. It also closes passageways into the ureters so
that urine cannot flow back into the kidneys. The tube through
which the urine flows out of the body is called the urethra.
What is
urinary diversion?
Urinary diversion is a term used when the bladder is removed
or the normal structures are being bypassed and an opening
is made in the urinary system to divert urine. The flow of
urine is diverted through an opening in the abdominal wall.
Individuals who might require urinary diversion are those
whose bladders were nonfunctional or had to be removed because
of either cancer or injury.
What are
the types of urinary diversion?
Urinary diversions may be divided into two types, continent
and non-continent. Non-continent urinary diversions involve
connecting the ureters to a segment of intestine and then
bringing the intestine to the surface of the abdomen. The
patient then wears an ostomy bag into which the urine continuously
drains, but he or she is still able to participate in strenuous
physical activity in addition to daily routines.
The second form
of urinary diversion — continent urinary diversion —
is subdivided into two basic types: those that have a surgical
opening brought out of the abdomen and those in which a replacement
bladder is made from part of the intestine. Those patients
with a new bladder are able to urinate spontaneously, whereas
those patients with a surgical opening need to place a tube
into the opening periodically to drain the accumulated urine.
The advantage of the two types of continent urinary diversions
is that no permanent ostomy bag needs to be worn.
What can be expected after
a urinary diversion?
Problems with urinary diversions may include alterations in
fluid and/or salt balance; difficulties in inserting the tube
in those with surgical openings in the abdomen; problems with
the skin growing over the surgical opening, and general complications
that might occur as a result of the abdominal operation —
bowel obstruction, urine leakage and bowel leakage. In general,
however, urinary diversions are tolerated extremely well.
Patient satisfaction is very high, and most patients are rehabilitated
to normal activity and a normal lifestyle.
Can I wear normal clothing if I have an ostomy bag?
Most individuals are able to wear clothes from their entire
wardrobe.
Will I be
on a special diet?
Yes, probably. Follow your doctor's orders regarding nutrition
at each stage of your adjustment.
