“…The Ho:YAG laser fragments all stone compositions and produces less stone migration (retropulsion) during treatment than the short pulsed lasers [10][11][12][13][14]. The dominant mechanism in Ho:YAG laser lithotripsy is photothermal along with minor effects of acoustic emission [15].…”

“…For minimally invasive surgery, pulsed laser light is delivered to the urinary system through an optical fiber in conjunction with an ureteroscope. Among many laser lithotriptors, Ho:YAG laser is considered to be the most efficient and versatile tool since it can fragment all compositions of urinary calculi and causes less retropulsive motion than the short pulsed lasers [4][5][6]. The fragmentation during Ho:YAG laser lithotripsy is initiated through direct pulse energy absorption in a calculus.…”

Background and Objectives: We tested Ho:YAG and Er:YAG laser ablation of human urinary calculi to determine if Er:YAG is a more efficient lithotripsy device. Study Design/Materials and Methods: Ablation efficiency of Ho:YAG and Er:YAG lasers was tested at varying energy settings, ranging from the damage threshold to clinical energy setting associated with Ho:YAG laser. Stones of known composition (calcium oxalate monohydrate (COM), cystine, and uric acid (UA)) were irradiated. Crater width, depth, and ablation volumes were determined using an optical coherence tomography (OCT). Results: For all stones and energy settings, the Er:YAG laser produced deeper craters and larger ablation volumes than Ho:YAG laser. The Ho:YAG laser created wider craters during the multiple pulse process and the shape of craters was irregular. Conclusions: The Er:YAG laser is more efficient than the Ho:YAG laser for lithotripsy. The deeper craters produced by the Er:YAG laser is attributed to the high absorption of energy at its wavelength.

“…Lasers can accomplish lithotripsy by having a photoacoustical/photomechanical effect (laser-induced shockwave lithotripsy) or a predominantly photothermal effect. Of the lasers commonly used in lithotripsy, the 1-μsec pulsed-dye laser is the most popular shockwave laser and has been extensively studied (12)(13)(14). This device is based on the excitation of coumarin dye to produce the monochromatic light that fragments the calculi (14).…”

“…This device is based on the excitation of coumarin dye to produce the monochromatic light that fragments the calculi (14). At 504 nm, a green light that is absorbed largely by the yellow-colored urinary calculi is produced, which allows it to be safely used without causing much damage to surrounding tissues (13). As the stone absorbs the energy from the laser, the excited ions that are released form a quickly expanding and pulsating cloud around the stone, creating a shock wave that then breaks the calculus into fragments (15).…”

“…Thus in the appropriate environment, fluid absorbs the energy and is heated as a result. A cloud of vapor is produced, parting the water and allowing the remaining portion of the laser light to directly contact the calculus surface, drilling holes into it and leading to its fragmentation (13). A study conducted by Cimino et al demonstrated that Ho:YAG laser lithotripsy is a more efficacious endoscopic technique for the treatment of ureteral stones with higher stone fragmentation rates compared to pneumatic lithotripsy, and a review conducted by Teichman concluded that this laser is safe, effective, and works just as well if not better than other modalities, and that it may also be used for biliary stones (20,21).…”

In modern medicine, lasers are increasingly utilized for treatment of a variety of pathologies as interest in less invasive treatment modalities intensifies. The physics behind lasers allows the same basic principles to be applied to a multitude of tissue types using slight modifications of the system. Multiple laser systems have been studied within each field of medicine. The term "laser" was combined with "surgery," "ablation," "lithotripsy," "cancer treatment," "tumor ablation," "dermatology," "skin rejuvenation," "lipolysis," "cardiology," "atrial fibrillation (AF)," and "epilepsy" during separate searches in the PubMed database. Original articles that studied the application of laser energy for these conditions were reviewed and included. A review of laser therapy is presented.Laser energy can be safely and effectively used for lithotripsy, for the treatment of various types of cancer, for a multitude of cosmetic and reconstructive procedures, and for the ablation of abnormal conductive pathways. For each of these conditions, management with lasers is comparable to, and potentially superior to, management with more traditional methods.
