Introduction
Intracorporeal lithotripsy provides a minimally invasive
means of stone management. Unlike extracorporeal shock
wave lithotripsy (ESWL), contemporary intracorporeal
lithotripters are used under direct visualization, allowing
for real-time confirmation of stone treatment. Use of the
various modalities of intracorporeal lithotripters has now
all but eclipsed open surgical methods of treating urinary
calculi. Indeed, intracorporeal lithotripsy is now recom-
mended by both the AUA and EAU as the preferred treat-
ment option for percutaneous nephrolithotomy and is
increasingly used and recommended for the management
of ureteral and bladder calculi [1, 2]. This review aims to
provide an overview of the various types of intracorporeal
lithotripters. This will include a discussion of the mechan-
ics of each instrument and/or a comparison of their uses
and effectiveness of action. One way of classifying these
lithotripters is by mechanism of action. They can be cat-
egorized into mechanical, ultrasonic, combination, electro-
hydraulic, and laser lithotripters.
Mechanical lithotripters
Mechanical lithotripters include ballistic lithotripters as
well as the manually operated bladder calculus fragmenters
which were the first lithotripters to be developed. The his-
tory of lithotripsy began in the early 1800s with physicians
attempting intravesical means of treating stones. Franz
von Gruithuisen developed the first model of a function-
ing lithotrite, the Steinbohrer or stone drill in 1813. It was
designed to drill holes into bladder calculi [3]. The term
lithotrite was coined by Jean Civiale who developed the
Abstract
Purpose Intracorporeal lithotripsy is becoming the most
commonly used surgical method of stone treatment in Urol-
ogy. The five major types of intracorporeal lithotripters are
ultrasonic, ballistic, and combination lithotripters as well as
laser and electrohydraulic lithotripters. The advantages and
disadvantages of choosing each of these treatment modali-
ties are reviewed.
Methods Extensive review of literature was performed to
identify the types of intracorporeal lithotripters. An inves-
tigation was undertaken of the early development of each
modality of intracorporeal lithotripsy and/or the mechanism
of action. Challenges of each technique were identified and
presented. Finally, a determination was made of how these
lithotripters compare on the basis of effectiveness of action
and cost based on information provided in primary litera-
ture as well as previous reviews of these modalities.
Results Contemporary lithotripters have found widespread
use in the management of urinary lithiasis. Holmium laser
lithotripsy has become one of the most commonly used
tools for intracorporeal lithotripsy.
Conclusion There is a wide variety of intracorporeal
lithotripters which can be chosen based on the characteris-
tics of each modality and the requirements of the urologist.
