Urology Laser Technology Has Emerged As an Effective Non-Invasive Procedure
The laser has attracted the
attention of the doctors as well as the patients for a long time. A lot of
lasers are being used in different medical fields today. A lot of lasers have
also been adopted by urology. Urology uses many different lasers including KTP laser, Diode
laser, Thulium laser & Holmium laser. Ophthalmology and dermatology used
the oldest known therapeutic lasers. A medical laser is a non-invasive and
effective light source for tissue treatment that provides rapid cure without
scarring or discoloration.
The evolution of lasers in urology
Over the last five decades, laser
technology has evolved into a highly specialized entity, finding a niche market
in the urology field as well. Lasers obtained from various lasing devices have
also been tested for urological applications, generating intensified light of
different wavelengths.
Currently, these lasers are most
widely used as intracorporeal lithotripters in the surgical treatment of benign
prostatic hyperplasia. Such applications include the ablation of various
urological tumors and the incising of upper and lower urinary tract strictures.
The technology is undergoing a relentless process of evolution, resulting in
surgical lasers getting safer, more effective, and more affordable.
What is a urology laser and what role does it have in modern-day urology?
The term laser is derived from
the first letters of the words of the phrase "Light Amplification by
Stimulated Radiation Emission". It is a monochromatic light-emitting
device. The light source may also include crystal, gas, dye, or semiconductor.
Urology laser surgical equipment
is used for incision and soft tissue resection and ablation of tumors. Laser
therapy is a medical treatment that uses a direct beam of light to cut, burn or
destroy tissues. Therapeutic lasers can be used in many medical treatment
areas. Ophthalmology and dermatology used the oldest known therapeutic lasers.
A medical laser is a non-invasive and effective light source for tissue
treatment that provides rapid cure without scarring or discoloration.
Laser therapies have become an
extremely popular treatment method for patients with benign prostatic
hyperplasia, urolithiasis, bladder tumors, and strictures of the urinary tract
or external genitalia lesions over the last two decades. Nowadays, due to the
advancement of equipment, a better understanding of the needs of urologists on
the part of producers, and a growing experience of laser treatment operators,
this is a favorable option for conventional urology surgical procedures. Easy
accessibility to the appropriate equipment, a relatively short learning curve,
and promising therapeutic effects have led to a higher interest in these
methods.
Prevalence of kidney stone diseases and subsequently increasing demand for urology laser technology
In the present era, the
prevalence of kidney stone disease has increased due to the effects on urinary
stone development of increased obesity, diabetes and improvements throughout
dietary habits. While minimally invasive therapies remain the pillar of
treatment in this new stone-affected generation, the use of ureteroscopy (URS)
has increased significantly, so that URS is now the most common surgical
therapy for upper urinary tract stones.
One explanation for the change
toward URS in practice was the widespread availability of the holmium laser,
which allows for lithotripsy in all stone locations, irrespective of stone
composition. With the proliferation of more efficient higher watt holmium
systems and developments in laser technology, possibilities for laser settings
and techniques for breaking down stones have increased for surgeons. The
surgical method for treating upper urinary tract stones with URS generally
consists of either fragmentation and successful basket retrieval or
fragmentation leading to small fragments left in place for spontaneous passage,
which is also known as the dusting technique.

laser for urolithiasis
Advanced urology laser techniques
are an essential tool for treating urolithiasis patients. The progress of the
ureteroscopes of the new generation and the increasing power of the lasers make
the lithotripsy of larger concretions shorter. More than 90 percent of lithotripsy
procedures are mostly successful. The effectiveness and protection of laser
lithotripsy have been demonstrated in numerous studies on symptomatic ureteral
stones at all sites, care of pregnant women, overweight/obese patients and
children of all ages.

Urology
laser for bladder tumors
Laser methods have also found a
place in the treatment of urinary bladder tumor patients. Nowadays, laser
resection procedures for bladder tumors are returning with the introduction of
new devices. Some reports suggest that the laser approach is preferable to
TURBT because it appears that cancer recurrence after laser treatment is not
more common than after TURBT and complication rates tend to be lower with
current laser procedures compared to TURBT. Laser vaporization is suitable as
an outpatient procedure because general anesthesia is not required.

Urology
laser for hyperplasia
Laser BPH treatment has evolved
from clotting to enucleation. Compared with transurethral resection and open
prostatectomy, blood loss is significantly reduced. Visual laser ablation of the
prostate triggers coagulative necrosis with secondary ablation and interstitial
laser coagulation. Long postoperative catheterization, unpredictable results
and high rates of reoperation have limited the use of these technologies. With
the marketing of new high-powered 80-W KTP and 100-W Ho lasers,
ablative/vaporizing techniques have once again become prevalent. Vaporization
removes tissue obstruction immediately. Short-term results are promising, but
there is a lack of large series, long-term outcomes, and randomized trials.
Holmium laser enucleation (HoLEP) permits the removal of whole prostate lobes,
mimicking the index finger operation of open prostatectomy.
Where does the industry lack?
When using lasers, protection is
very critical. To prevent severe injuries, all intra-operative personnel have
to wear proper protection. Although lasers with holmium: YAG (Ho: YAG) do not
penetrate as deeply, if they are aimed at the unprotected area, they can cause
defects. Suitable draping should be used for all lasers to protect outside
areas, with wet towels, draped over cutaneous lesions. Preferably, reflective
surfaces have to be kept away from the treatment field; nevertheless, the
treatment field should be draped with wet drapes if this is not feasible. In
fact, if oxygen is in use anywhere in the operational area, it is very risky to
use a laser as this can result in a laser fire and serious burns.
To conclude
The urology laser market has witnessed a rapid prominence in the
treatment of various diseases. Further, the growing need for non-invasive
treatments is a significant factor that drives the growth of the market. Laser
procedures have several benefits over conventional surgeries. First is more
accuracy and precision. Secondly, laser procedures are much less invasive,
laser energy heat-seals blood vessels, with less bleeding, swelling, pain, or
scarring. Second, laser procedures are a great alternative for high comorbidity
patients who may not be suited to open operations.
In comparison, laser treatment
and hospitalization time may be shorter, and more procedures may be conducted
in outpatient environments. Laser techniques are flexible urological devices.
Their use in prostate disease patients is particularly significant. Promising
therapeutic effects of laser treatments tend to show their use in treating
patients with other illnesses.
