“…The table lists demographic characteristics of the 116,115 patients with a mean age of 50.8 years (range 18 to 101) who comprised the OKSC. 15 The mean age of patients treated with SWL, URS and PCNL was 50.4 (range 18 to 96), 50.8 (range 18 to 101) and 54.6 years (range 18 to 94), respectively. During the study period the rate of kidney stone procedures performed per year increased steadily by approximately 48% from 85/100,000 to 126/100,000 population.…”

INTRODUCTIONFollowing the initial description of the holmium: yttrium-aluminum-garnet (HoYAG) laser for the treatment of kidney stones in the mid 1990's, endourologic management of kidney stones has seen a renaissance of sorts. [1][2][3] This is in large part due to the fact that the HoYAG laser has been shown to reliably fragment stones of all compositional varieties while maintaining an appropriate margin of safety. 4 It is not surprising, then, that surgical techniques such as ureteroscopy and percutaneous nephrolithotomy (PCNL), procedures which both commonly utilize the HoYAG laser, are being increasingly performed relative to shockwave lithotripsy for the management of kidney stones. 5,6 Current practice guidelines advocate PCNL as the preferred treatment for large renal stones. 7,8 Traditional methods of lithotripsy during PCNL have relied upon ultrasonic, ballistic, or a combination of these energy delivery devices. As the power of HoYAG lasers has increased, use of this technology during PCNL as a means to fragment renal stones has been suggested as a safe and effective alternative treatment modality. 9 Recognizing this potential, several urologic device manufacturers have developed novel instruments, known as laser-suction handpieces (LSHP), that couple the HoYAG laser with suction for use during PCNL.Since these devices are fundamentally different than the traditional lithotrites familiar to urologists, ergonomics and ease of use will be important factors impacting their widespread adoption, an area that has not been studied.Recognizing this, we tested three LSHP at the time of PCNL in a porcine model. In particular, we focused on the ergonomic aspects of these devices and the ease that they can be manipulated by using a questionnaire completed by the operating surgeon. We also assessed the general effectiveness of stone fragmentation and suction as well as safety of the three LSHP. METHODS Tested devicesThree LSHP were tested in this study. These included the LASER Suction Tube (Karl Storz ® , Germany) and LithAssist™ (Cook ® Medical, USA), both of which are currently commercially available, as well as the Suction HP (Lumenis ® , Israel), a new device awaiting FDA approval (Figure 1). Each device couples laser energy with suction, allows the surgeon to precisely control the length of exposed fiber, and is introduced through a typical rigid nephroscope working channel. The devices are of comparable length and diameter. The device lengths were 40cm, 38cm, and 40cm and outer diameter of the suction tubes were 12F, 11.6F, and 11.3F for the LASER Suction Tube, LithAssist, and Suction HP, respectively. We tested the Suction HP at a 3:1 frequency relative to the LASER Suction Tube and LithAssist as this device is a prototype. Reverse PCNL procedure and lithotripsyAfter obtaining study approval from the Animal Research Committee at Methodist Hospital (Indianapolis, Indiana), reverse PCNL was performed in 4 adult, female domestic farm pigs. Pigs were anesthetized and intubated by a certified animal technician...
