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.

Background

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.

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.
