Effects
of Percutaneous Placement of J-J Catheter
Placement of J-J would be able to relieve
obstruction and enable urine flow.

Candidates for Percutaneous Placement of J-J
Catheter
Ideal
candidates are patients who are diagnosed with
kidney stones.

Your Consultation
The
doctor would need to get the patient's clinical
history, examination and imaging, usually in the
form of X-rays or a CT scan.

The
Percutaneous Placement of J-J Catheter Procedure
There
are times when it is necessary to insert a
hollow plastic tube into the urinary tract prior
to lithotripsy. This tube is called a J-J stent.
One end of the stent coils up in the kidney, and
the other coils up in the urinary bladder. If
the urologist at the Center inserts a J-J stent,
the patient and the referring urologist will be
informed of its placement. It is absolutely
mandatory that this stent be removed by the
referring urologist.

Recovery
This
procedure does not require any surgery so
recovery is relatively quick and easy.

Risks
Prolonged JJ stent placement was associated with
return of intrapelvic pressure to normal but
persistent changes in both renal and ureteric
motility and also calculus transit time.
Frequently Asked Questions
Q:
What is a kidney stone?
A:
Kidney (renal) stone is a mixture of salt or
crystals and minerals can that come together and
grow as stones in a solution (i.e. urine in this
case).
Q: What causes
kidney stones?
A:
There are no definite answers but it appears
that there is a mix of genetic factors (the risk
of stones tends to run in families) and
environmental factors such as a hot climate or
your dietary intake.
Stones
tend to occur in the 20-40's age group and are
three times as common in men as compared to
women. Other factors include abnormalities of
the urinary tract system, recurrent urinary
tract infections and some metabolic disorders.
Q:
What is the treatment for kidney stones?
A:
Treatment varies according to size and position
of the stone within the urinary tract. The size
of the stone can range from a small pinhead to
the size of a walnut, completely filling the
kidney collecting system. Smaller stones may
pass spontaneously, however if the stone is too
big, intervention may be necessary.
The
actual treatment will depend on your clinical
history, examination and imaging, usually in the
form of X-rays or a CT scan. Nowadays, with the
advent of advanced instruments and telescopes,
the stone can usually be removed without making
any incisions.
Other
methods of treating stones include percutaneous
nephrolithotomy (PCNL), which is a form of
keyhole surgery, or dissolution therapy where
the stone can be dissolved by changing the
acidity of the urine. In some instances,
lithotripsy can be used to shatter the stone
using a focused, magnified, sound wave.
Your
surgeon will discuss with you the best options
for stone removal at your consultation.
Q: What happens
after a J-J stent is placed?
A:
In
situ JJ stents impair upper urinary tract
motility and experimental calculus transit time
and may delay passage of ureteric calculi or
calculus fragments following extracorporeal
shock wave lithotripsy.
Q:
What happens when a stent is left inside for a
long time?
A:
Stents that are allowed to remain in place for
an extended period can become covered with
calcium and require other surgical procedures to
remove them. Sometimes the urologist inserting
the stent will choose to leave a string on the
stent. This makes it easier to remove at a later
time by the referring urologist.
