SUMMARY
E x t r a c o r p o real shock wave lithotripsy or ure t e ro l i-
thotripsy for the treatment of calculi in the lower ure-
ter.
Two therapies, ureterolithotripsy (URL) and extracorpo -
real shock wave lithotripsy (ESWL) can be used in the
t reatment of lower ureteral calculi. In a re t ro s p e c t i v e
analysis ure t e rolithotripsy and extracorporeal shock
wave lithotripsy for lower ureteral calculi were compa -
red to evaluate morbidity. During a 3 year period 161
patients treated with ure t e rolithotripsy and 71 who
u n d e rwent extracorporea l shock wave lithotripsy
(Siemens Lithostar) were analysed as to the success rate,
effectiveness quotient, complication rate and length of
hospitalization.
Followup consisted of ultrasound and a plain film of the
kidneys, ureteres and bladder 1 day and 1 to 3 months
p o s t o p e r a t i v e l y. Complete removal of all stone frag -
ments was achieved in 95.5% of the patients tre a t e d
e n d o u rologically with a 1.2% re t reatment rate. In the
group treated with extracorporeal shock wave lithotrip -
sy success rate was 82.1% with a 19.6% re t re a t m e n t
r a t e . Among the patients who underwent ure t e ro s c o p y
and stone removal 16.1% had complications compared
to 10.7% in the ESWL group. The mean stone diameter
was 0.8 cm in the endourological group and 0.7 cm in
the ESWL group. Stone size was not a determining fac -
tor for the stone free rate and effectiveness quotient in
the patients treated endourologically. Indeed, in patients
who underwent ESWL for large stones the stone-fre e
rate and effectiveness quotient decreased to 78.9% and
57.7%.Ureterolithotripsy will continue to have a prima -
ry role in the management of lower ureteral stones. A s
e x t r a c o r p o real shock wave lithotripsy is an effective
noninvasive procedure, requiring no anesthesia and hos -
pitalization as routine, it may be considered an alterna -
tive either primarily or after failed ureteroscopy.
