Evaluation of intrarenal pressure stability at different lithotripter suction settings in a porcine kidney model

Strittmatter, F., Nagele, U., Schachtner, J. et al. Evaluation of intrarenal pressure stability at different lithotripter suction settings in a porcine kidney model. World J Urol (2021).


Intrarenal pressure levels with different suction levels were evaluated for Storz® Nephroscopes MIP-M and MIP-L in combination with Swiss LithoClast® Trilogy probes in an ex vivo porcine kidney model. 

Stone clearance times with mini-percutaneous nephrolithotomy: Comparison of a 1.5 mm ballistic/ultrasonic mini-probe vs. laser.

Timm B., et al. Canadian Urological Association Journal vol. 15,1 (2021): E17-E21.

Mini-percutaneous nephrolithotomy (Mini-PCNL) is a minimally invasive endoscopic procedure that requires a specific technique, as it utilizes relatively small instruments within restricted diameter access (to even 5 French or smaller). Treating renal calculi through the narrow working lumen of mini-nephroscopes represents the major challenge when conducting mini-PCNL.

Case report: the end of “cutting for stone”? Using the Swiss LithoClast® Trilogy for cystolitholapaxy on a 4 cm bladder stone per urethra.

Sninsky B. C. et al. Urology Case Reports vol. 26 (2019) 100964.


The gold standard for managing extremely large or multiple bladder stones is still open cystolithotomy. In general, open surgical procedures are associated with more frequent complications than endoscopic ones. A traditional approach may be very challenging, especially in individuals with specific anatomical or physiological restrictions such as contractures or poor wound healing. Another aspect that has to be taken into account when treating patients with comorbidities is the type of energy used to fragment stones. When using a holmium laser, fragmentation and removing large bladder calculi may require a considerable amount of procedural time and the need for prolonged general anesthesia. Dual-energy lithotripters, on the other hand, present a better efficiency profile. Therefore, Swiss LithoClast® Trilogy - a single-probe device that combines electromagnetic impactor with ultrasonic energy and suction may serve as the best treatment solution in complex cases. 

Initial Clinical Experience with Swiss LithoClast® Trilogy during Percutaneous Nephrolithotomy

Nottingham C. U. et al. Journal of Endourology, vol. 34,2 (2020): 151-155.

Study background 

Percutaneous nephrolithotomy (PCNL) is a gold standard treatment in patients with renal stones >20 mm in diameter. Several in vitro and laboratory model studies provided robust evidence on Swiss LithoClast® Trilogy efficiency. This modern, single-probe device delivers both ultrasonic energy and electromagnetic ballistic impact with a simultaneous suction capability.

A prospective comparative study of mini‑PCNL using Swiss LithoClast® Trilogy or Thulium Fiber Laser with suction

Abhijit Patil, Rohan Sharma, Darshit Shah, Ankit Gupta1, Abhishek Singh, Arvind Ganpule, Ravindra Sabnis, Mahesh Desai, Department of Urology, Muljibhai Patel Urological Hospital, Nadiad, India “A prospective comparative study of mini-PCNL using Trilogy®  or Thulium Fiber Laser with suction.” World Journal of Urology, 10.1007/s00345-021-03881-5. 28 Nov. 2021.

This prospective study aimed to evaluate and compare the efficiency of Swiss LithoClast® Trilogy and Thulium Fiber Laser in Mini-PCNL.

EMS Lithoclast Trilogy: an effective single-probe dual-energy lithotripter for mini and standard PCNL

Sabnis R. B. et al. World Journal of Urology vol. 38,4 (2020): 1043-1050. 

Providing fast, easy, and safe percutaneous nephrolithotomy (PCNL) appears to be one of the most challenging issues in modern urology. In order to break the stones more effectively, a combination of different energy sources is needed. Swiss LithoClast® Trilogy is an all-in-one-probe, dual-energy lithotripter that combines electromagnetic impactor and ultrasonic vibration with suction capability. This study describes the initial clinical use of Swiss Lithoclast® Trilogy in patients who underwent Mini or Standard PCNL for stone evacuation.

Comparative evaluation between one ultrasonic and two single-probe dual energy lithotripters: in vitro and in vivo experiment in a porcine model

M.Lattarulo et. al

Swiss LithoClast®️ Trilogy has been designed to provide powerful fragmentation and more efficient stone removal for shorter PCNL procedural time. Scientific research proves this effectiveness, in comparison to other, existing lithotripters, as well as in actual OR cases.
In a new study, Lattarulo et al. tested the Swiss LithoClast Trilogy in vitro and in vivo in porcine model, and concluded that the device is twice as fast on both soft and hard stones as compared with best competitors.
