As many as 5 percent
of all Americans will be affected by urinary stones
during their lifetime. Men have an increased risk
compared to women. The recurrence rate can be as
high as 50 percent up to five years after the
initial stone episode.
Depending on stone
size, up to 85-90 percent of stones are passed
spontaneously without intervention (surgery or other
procedure), although some treatment may be required
for symptomatic relief such as IV fluid and pain
medications. Current surgical treatments for stones
are far less invasive than fifteen to twenty years
ago. At that time, many stone had to be retrieved
through open incisions. Currently we reserve open
surgical stone removal for very large stone cases.
Extracorporeal shock
wave lithotripsy (ESWL) is currently the preferred
treatment for many urinary stones and is usually
effective in eliminating the offending stone from
the urinary tract. This technology utilizes the
imoact of focused sound waves on the stone to crack
it into small passable fragments. Another option
for larger stones is percutaneous ultrasonic
lithotripsy (PUNL) that places a small "straw" into
the kidney from the back and allows direct
visualization and breaking-up of stones using
ultrasound. Removal of stones in the ureter is done
under direct vision using specialized endoscopes,
called ureteroscopes. We can use laser energy to
break the stones into small fragments that can be
retrieved with baskets. ESWL and ureteroscopy are
typically performed in an outpatient setting.
The physicians at
Central Arizona Urologists have expertise in all
areas treatment and evaluation of urinary tract
stone disease. We will discuss all of the various
options for an individual's presentation and arrive
at the best treatment option.
