URINARY STONE & SWL
Urolithiasis is a condition which results in
complete or partial, acute or chronic, continuous or
intermittent blockage of the urinary tract due to abnormal
collection of mineral salts (often calcium).
Urinary calculi have plagued men for centuries
(men develop stones twice as often as women) and affect some
individuals according to predisposing inherited biochemical or
anatomic factors and environmental influence.
Roughly 2% to 3% of the world
population suffers from kidney or urethral stones during their
The consequences of urinary calculi are
responsible for 10% of urological hospital admissions
worldwide. Although urinary calculi may be eliminated
naturally by the body, natural elimination is frequently
accompanied by considerable pain and very often by serious
complications, such as obstruction and infection of the
Urinary stones may consist of several
The most frequently found are:
• calcium oxalate and phosphate
magnesium ammonium phosphate (struvite)
• uric acid
Urinary stones may be located in
different places inside the urinary tract in the renal
cavities (the calyces and the pelvis), in the ureter, in
the bladder or the urethra.
The stones form most frequently in one
of the kidneys, from where, following the flow of urine,
they tend to migrate along the ureter towards the
bladder. From the bladder they move along the urethra
towards the outside.
Urolithiasis may also occurs with
various inherited and metabolic disorders and following
urinary tract infections.
When not treated, urinary obstruction can
become very serious and in addition to its negative impact on
quality of life, can lead to a dilation of the urinary tract
and eventual loss of functioning renal tissue.
PREVENTION OF UROLITHIASIS
The primary way to try to prevent kidney
stones is to drink plenty of fluids, ideally water. This high
volume of fluid moving through the urinary tract keep small
crystals moving through the kidneys and decrease the
likelihood for a stone to develop.

majority of cases, surgical manipulation is not
necessary, but exact identification of stone and
rigorous patient selection is important for an accurate
treatment of the disease.
Extracorporeal Shock Wave
Lithotripsy (ESWL) is a non-invasive technique for
disintegration of urinary calculi. Since its
introduction in clinical practice nearly 20 years ago,
SWL has become the standard treatment for urinary
calculi. This solution reduces stones to fragments using
shock waves and is the most common way to treat stones
that will not pass on their own. As a non-surgical
procedure this technique, not requiring any analgesia
without hospital stay, is an ideal treatment alternative
for patients suffering from urolithiasis.
